Arthritis is a term often used to mean any disorder that affects joints. Symptoms generally include joint pain and stiffness. Other symptoms may include redness, warmth, swelling, and decreased the range of motion of the affected joints. In some types, other organs are also affected. Onset can be gradual or sudden.

There are over 100 types of arthritis. The most common forms are osteoarthritis (degenerative joint disease) and rheumatoid arthritis. Osteoarthritis usually occurs with age and affects the fingers, knees, and hips. Rheumatoid arthritis is an autoimmune disorder that often affects the hands and feet. Other types include gout, lupus, fibromyalgia, and septic arthritis. They are all types of rheumatic disease.

Types of Arthritis

There are several diseases where joint pain is primary and is considered the main feature. Generally, when a person has “arthritis” it means that they have one of these diseases, which include:

  • Osteoarthritis
  • Rheumatoid arthritis
  • Gout and pseudo-gout
  • Septic arthritis
  • Ankylosing spondylitis
  • Juvenile idiopathic arthritis
  • Still’s disease

Joint pain can also be a symptom of other diseases. In this case, the arthritis is considered to be secondary to the main disease; these include:

  • Psoriasis (Psoriatic arthritis)
  • Reactive arthritis
  • Ehlers-Danlos Syndrome
  • Hemochromatosis
  • Hepatitis
  • Lyme disease
  • Sjogren’s disease
  • Hashimoto’s thyroiditis
  • Celiac disease
  • Non-celiac gluten sensitivity
  • Inflammatory bowel disease (including Crohn’s disease and ulcerative colitis)
  • Henoch–Schönlein purpura
  • Hyperimmunoglobulinemia D with recurrent fever
  • Sarcoidosis
  • Whipple’s disease
  • TNF receptor-associated periodic syndrome
  • Granulomatosis with polyangiitis (and many other vasculitis syndromes)
  • Familial Mediterranean fever
  • Systemic lupus erythematosus

Undifferentiated arthritis is arthritis that does not fit into well-known clinical disease categories, possibly being an early stage of definite rheumatic disease.

Symptoms of Arthritis

Extra-articular features of the joint disease
  • Cutaneous nodules
  • Cutaneous vasculitis lesions
  • Lymphadenopathy
  • Edema
  • Ocular inflammation
  • Urethritis
  • Tenosynovitis (tendon sheath effusions)
  • Bursitis (swollen bursa)
  • Diarrhea
  • Orogenital ulceration

 

 

Pain, which can vary in severity, is a common symptom in virtually all types of arthritis. Other symptoms include swelling, joint stiffness and aching around the joint(s). Arthritic disorders like lupus and rheumatoid arthritis can affect other organs in the body, leading to a variety of symptoms. Symptoms may include:

  • Inability to use the hand or walk
  • Stiffness, which may be worse in the morning, or after use
  • Malaise and fatigue
  • Weight loss
  • Poor sleep
  • Muscle aches and pains
  • Tenderness
  • Difficulty moving the joint

It is common in advanced arthritis for significant secondary changes to occur. For example, arthritic symptoms might make it difficult for a person to move around and/or exercise, which can lead to secondary effects, such as:

  • Muscle weakness
  • Loss of flexibility
  • Decreased aerobic fitness

These changes, in addition to the primary symptoms, can have a huge impact on quality of life.

In-Depth Report of Arthritis

Osteoarthritis, also known as degenerative joint disease, is the most common form of arthritis. In this disorder, a joint loses cartilage, the slippery material that cushions the ends of bones, over time.

Osteoarthritis is a chronic disease of the joint cartilage and bone, often thought to result from “wear and tear” on a joint. Joints appear larger, are stiff and painful, and usually feel worse with increased use throughout the day.Exercise, such as weightlifting, helps build muscle that is usually lost with age and puts stress on bones, helping keep them strong and healthy. Rheumatoid arthritis is a body-wide (systemic) autoimmune disease that initially attacks the synovium, a connective tissue membrane that lines the cavity between joints and secretes a lubricating fluid.

As a result, the bone beneath the cartilage changes and develops bony overgrowth. The tissue that lines the joint can become inflamed, the ligaments can loosen, and the muscles around the joint can weaken. The patient feels pain and movement limitations when using the joint.

Joints of affected Arthritis

Joints provide flexibility, support, stability, and protection. Specific parts of the joint: the synovium and cartilage, provide these functions.

  • Synovium –The synovium is the tissue that lines a joint. Synovial fluid is a lubricating fluid that supplies nutrients and oxygen to cartilage.
  • Cartilage  The cartilage is a slippery tissue that coats the ends of the bones. Cartilage is composed of four components:
  • Water –  Cartilage is composed mostly of water, which decreases with age. About 85% of cartilage is water in young people. Cartilage in older people is about 70% water.
  • Chondrocytes – Chondrocytes, the basic cartilage cells, are critical for joint health.
  • Proteoglycans – These large molecules bond to water, which keeps high amounts of water in cartilage.
  • Collagen – This essential protein in cartilage forms a mesh to give the joint support and flexibility. Collagen is the main protein found in all connective tissues of the body, including the muscles, ligaments, and tendons.

The combination of collagen mesh and water forms a strong and slippery pad in the joint. This pad cushions the ends of the bones in the joint during muscle movement.

Osteoarthritis Disease Progress

Deterioration of Cartilage. Osteoarthritis develops when cartilage in a joint deteriorates. The process is usually slow.

  • In the early stages of disease, the surface of the cartilage becomes inflamed and swollen. The joint loses proteoglycan molecules and other tissues. This joint then begins to lose water. Fissures and pits appear in the cartilage.
  • As the disease progresses and more tissue is lost, the cartilage starts to get hard. As a result, it becomes increasingly prone to damage from repetitive use and injury.
  • Eventually, large amounts of cartilage are destroyed, leaving the ends of the bone within the joint unprotected.

Complicating the process are abnormalities in the bone around arthritic joints. As the body tries to repair damage to the cartilage, problems can develop:

  • Clusters of damaged cells or fluid-filled cysts may form around the bony areas or near the fissures in the cartilage.
  • Fluid pockets may also form within the bone marrow itself, causing swelling. The marrow, which runs up through the center of the bone, is rich in nerve fibers. As a result, these injuries may cause pain in many patients with osteoarthritis.
  • Bone cells may respond to damage by multiplying, growing, and forming dense, misshapen plates around exposed areas.
  • At the margins of the joint, the bone may produce outcroppings, on which new cartilage cells (chondrocytes) multiply and grow abnormally.

Location of Osteoarthritis

Unlike some other types of arthritis, such as rheumatoid arthritis, osteoarthritis is less likely to involve many joints around the body or migrate around one joint to another. Rather, it affects one or several joints, often joints that have received extra wear. Osteoarthritis affects joints differently depending on their location in the body.

  • It is common in joints of the fingers, feet, knees, hips, and spine.
  • It sometimes occurs in the wrist, elbows, shoulders, and jaw, but it is not common in these locations.

Causes of Arthritis

The exact causes of osteoarthritis are not known. Scientists think that osteoarthritis likely develops from a combination of factors, including genetic susceptibility to joint injury.

Aging cells

  • The body’s ability to repair cartilage deteriorates with increasing age. Although osteoarthritis generally accompanies aging, osteoarthritic cartilage is chemically different from normal cartilage of the same age. As chondrocytes (the cells that makeup cartilage) age, they lose their ability to make repairs and produce more cartilage. This process likely plays an important role in the development and progression of osteoarthritis.

Genetic factors

  • Osteoarthritis tends to run in families. Genetic factors may be involved in about half of osteoarthritis cases in the hands and hips and in a somewhat lower percentage of cases in the knee. Several genes that might contribute to an inherited risk are under investigation.

Inflammatory response

  • The inflammatory response is an overreaction of the immune system to an injury or other assault in the body, such as an infection. This response causes specific immune factors, called cytokines, to gather in injured areas and cause inflammation and damage to body tissue and cells. The inflammatory response plays an important role in rheumatoid arthritis and other muscle and joint problems associated with autoimmune diseases.
  • Inflammation probably plays at most a minor role in the formation of osteoarthritis and is more likely to be a result — not a cause — of the disease. However, inflammation may play an important role in the progression of osteoarthritis and in its chronic nature. The effects of the inflammatory response in osteoarthritis are likely to be different, and less severe, from those in rheumatoid arthritis.

Joint injury 

  • Joint damage from injuries or recurrent stress to the joint is the starting point in the osteoarthritis disease process. Osteoarthritis sometimes develops years after a single traumatic injury to or near a joint. Patients with knee injuries may be up to five times more likely to have osteoarthritis in the injured knee than those without injuries, and patients with hip injuries may be more than three times more likely to develop arthritis in the injured hip. Proper treatment of injuries, such as surgical repair of ligament tears in the knee with a strong rehabilitation approach, may help prevent the development of osteoarthritis.

Others medical condition that can causes arthritis

Other causes of osteoarthritis include

  • Bleeding disorders that cause bleeding in the joint, such as hemophilia
  • Disorders that block the blood supply near a joint, such as avascular necrosis
  • Complications of persistent, inflammatory arthritic conditions, particularly chronic gout, pseudogout, or rheumatoid arthritis
  • Conditions that cause iron build-up in the joints, such as hemochromatosis

Symptoms of Arthritis

The pain of osteoarthritis typically begins gradually after age 40 and progresses slowly over many years. Younger people with the condition may have no symptoms at all. Osteoarthritis is commonly identified by the following symptoms:

  • Pain that worsens during activity and gets better during rest. This is the most common symptom of osteoarthritis. As the disease advances, the pain may occur even when the joint is at rest.
  • Pain is generally described as aching, stiffness, and loss of mobility. The symptoms are often worse when resuming activities after periods of no activity.
  • The pain may be intermittent, with bad spells followed by periods of relative relief.
  • Pain seems to increase in humid weather.
  • Some people have muscle spasm and contractions in the tendons.
  • Some people feel a grating sensation when the joint is used. Osteoarthritis in the knee may cause a crackling-like noise (called crepitus) when the affected knee is moved.

Symptoms by Location of Arthritis

Hand  Osteoarthritis of the hand occurs most often in older women and may be inherited within families. The following joints are most frequently affected:

  • Distal interphalangeal (DIP) joint  The first joint below the fingertips is the most common location of osteoarthritis of the hand. These joints can develop bony growths known as Heberden’s nodes.
  • Carpometacarpal (CMC) joint – The joint at the base of the thumb, where the thumb joint connects with the wrist, is the second most common location.
  • Proximal interphalangeal (PIP) joint – The middle joints of the fingers can also develop osteoarthritis. These joints may develop small, solid lumps (nodules) known as Bouchard’s nodes.

Osteoarthritis of the hand may predict the later development of osteoarthritis in the hip or knee.

  • Knee –  Osteoarthritis is particularly debilitating in the weight-bearing joints of the knees. The meniscus, the cartilage pad between the joint formed by the thighbone and the shinbone, plays an important role in protecting this joint. It acts as a shock absorber. The joint is usually stable until the disease reaches an advanced stage when the knee becomes enlarged and swollen. Although painful, the arthritic knee usually retains reasonable flexibility.

 

arthritis

  • Hips – About 1 in 4 people develop hip arthritis over the course of their lifetime. Being obese increases the risk. Osteoarthritis frequently strikes the weight-bearing joints in one or both hips. Pain develops slowly, usually in the groin and on the outside of the hips, or sometimes in the buttocks. The pain also may radiate to the knee, confusing the diagnosis. Those with osteoarthritis of the hip often have a restricted range of motion (particularly when trying to rotate the hip) and walk with a limp, because they slightly turn the affected leg to avoid pain.
  • Spine  Osteoarthritis may affect the cartilage in the disks that form cushions between the bones of the spine, the moving joints of the spine itself, or both. Osteoarthritis in any of these locations can cause pain, muscle spasms, and diminished mobility. In some cases, the nerves may become pinched, which also produces pain. Advanced disease may result in numbness and muscle weakness. Osteoarthritis of the spine is most troublesome when it occurs in the lower back or in the neck, where it can cause difficulty in swallowing.
  • Shoulder- Osteoarthritis is less common in the shoulder area than in other joints, but it may develop in the shoulder joint (the glenohumeral joint). In such cases, it is most often associated with a previous injury, and patients gradually develop pain and stiffness in the back of the shoulder. Osteoarthritis also can develop in the acromioclavicular (AC) joint, which is between the shoulder blade and the collarbone. However, it rarely causes symptoms in this location.

Risk Factors

In the U.S., osteoarthritis affects about 27 million Americans age 25 years and older.

Age

  • Osteoarthritis can affect people of any age, but it is much more common in older people. It rarely occurs in people younger than age 40.

Gender

  • In people younger than 45, osteoarthritis occurs more frequently in men. After age 45, it develops more often in women. Some research suggests that women may also experience greater muscle and joint pain, in general, than men.

Obesity

  • Obesity, defined as being 20% over one’s healthy weight, places people (particularly women) at increased risk for osteoarthritis. It also worsens osteoarthritis once deterioration begins. This higher risk is due to increased weight on the joints.

Work and leisure factors

  • Because injuries can trigger the disease process, people whose work or leisure activities place them at risk for muscle and joint injuries may face a higher risk for osteoarthritis later on.
  • Workers at Higher Risk  Certain occupations with repeated stressful motions (such as squatting or kneeling with heavy lifting) can contribute to the deterioration of cartilage. People with jobs that require kneeling or squatting for more than an hour a day are at high risk for knee osteoarthritis. Jobs that involve lifting, climbing stairs, or walking also pose some risk.
  • Exercise –  There has been some question about the role of strenuous exercise in osteoarthritis. Sports that definitely pose a higher risk for osteoarthritis have a repetitive or direct joint impact (such as football), joint twisting, or both (baseball pitching, soccer). The increase in exercise intensity by young girls, including increased incidence of significant injuries, has raised concerns that we may see an increase in the incidence of future osteoarthritis.
  • Regular and moderate exercise –  however, is important for everyone and does not increase the risk for osteoarthritis. Recreational weight-bearing exercise (walking, jogging), done by middle-aged and elderly people, neither prevents osteoarthritis nor increases risk. Furthermore, many factors associated with a sedentary life (such as muscle weakness and obesity) are associated with a higher risk for osteoarthritis.

Physical Deformities

  • Some people are born with anatomical abnormalities, such as mismatched surfaces on the joints, which could be damaged over time. Legs of unequal length or skewed feet can cause jerky movement and may cause osteoarthritis.

Treatment of Arthritis

Osteoarthritis itself is not life-threatening, but a person’s quality of life can significantly deteriorate as a result of pain and lost mobility. No treatment can cure osteoarthritis, and none can alter its progression with certainty, but many available treatments can relieve symptoms and significantly improve the quality of life.

The goals of osteoarthritis treatment are to reduce pain and improve joint function. Treatment approaches include:

  • Lifestyle Changes Lifestyle modifications and non-drug therapies are an important first step for treatment and are used in combination with other treatment modalities. Lifestyle measures include exercise, weight loss, hot and cold therapies, and pain management techniques.
  • Medications  For mild pain relief, doctors recommend acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), and topical ointments. Patients with more severe pain may require stronger narcotic pain medication, corticosteroid injections, or visco-supplementation with injections of hyaluronic acid drugs.
  • Surgery –For severe osteoarthritis that is not helped by other treatments, surgery such as joint replacement may be considered.

Diagnosis of Arthritis

Osteoarthritis is often visible in x-rays. Cartilage loss is suggested by certain characteristics of the images:

  • The normal space between the bones in a joint is narrowed.
  • There is an abnormal increase in bone density.
  • Bony projections, cysts, or erosions are visible.

If the doctor suspects other conditions, or if the diagnosis is uncertain, additional tests are necessary.

It is important to note that a negative x-ray does not rule out osteoarthritis. Likewise, some people may have minimal symptoms even though an x-ray clearly shows they have arthritis.

An MRI exam of an arthritic joint is generally not needed, unless the doctor suspects other causes of pain.

Physical Examination

The affected joint in patients with osteoarthritis will generally be tender to pressure right along the joint line. Joint movement may cause a crackling sound. The bones around the joints may feel larger than normal. The joint’s range of motion is often reduced, and normal movement is often painful.

Blood tests

Blood test results may help identify other causes of arthritis (if present) besides osteoarthritis. Some examples include:

  • Elevated levels of rheumatoid factor (specific antibodies in the synovium) are usually found in patients with rheumatoid arthritis
  • The erythrocyte sedimentation rates (ESR, or “sed rate”) indicates inflammatory arthritis or related conditions, such as rheumatoid arthritis or systemic lupus erythematosus.
  • Elevated uric acid levels in the blood may indicate gout.

A number of other blood tests may help identify other rheumatological illnesses.

Test of the synovial fluid

If the diagnosis is uncertain or infection is suspected, a doctor may attempt to withdraw synovial fluid from the joint using a needle. There will not be enough fluid to withdraw if the joint is normal. If the doctor can withdraw fluid, problems are likely, and the fluid will be tested for factors that might confirm or rule out osteoarthritis:

  • Cartilage cells in the fluid are signs of osteoarthritis.
  • A high white blood cell count is a sign of infection, gout, pseudogout, or rheumatoid arthritis.
  • Uric acid crystals in the fluid are an indication of gout.
  • Other factors may be present that suggest different arthritic conditions, including Lyme disease and rheumatoid arthritis.
  • In people with known osteoarthritis, researchers may look for certain factors in synovial fluid (sulfated glycosaminoglycan, keratin sulfate, and link protein) that can suggest a more or less severe condition.

Ruling out conditions with similar symptoms

Numerous conditions cause symptoms of joint aches and pains. Something as simple as sleeping on a bad mattress or as serious as cancer can mirror symptoms of osteoarthritis. Other problems that can cause aches and pains in the joints include physical injuries, infections, tendinitis, and poor circulation.

Osteoarthritis can generally be distinguished from other joint diseases by considering several factors together:

  • Osteoarthritis usually occurs in older people and is located in only one or a few joints.
  • The joints are less inflamed than in other arthritic conditions.
  • Progression of pain is usually gradual.

Below are a few of the most common disorders that can be confused with, or may even accompany, osteoarthritis.

Rheumatoid Arthritis  Osteoarthritis can be confused at times with milder forms of rheumatoid arthritis, particularly when osteoarthritis affects multiple joints in the body. It normally occurs earlier in life than osteoarthritis, often striking people in their 30s and 40s. Rheumatoid arthritis affects many joints, and often occurs symmetrically on both sides of the body. People with rheumatoid arthritis generally have morning stiffness that lasts for at least an hour. (Stiffness from osteoarthritis usually clears up within half an hour.) Although osteoarthritis can occasionally cause swollen, red joints, this appearance is much more typical of rheumatoid arthritis and other types of inflammatory arthritis. In addition to blood tests, x-rays can help show differences between rheumatoid arthritis and osteoarthritis.

Chondrocalcinosis (Pseudogout) –  Chondrocalcinosis (pseudogout syndrome) is a disease in which a certain type of calcium crystals known as CPPD (calcium pyrophosphate dihydrate) accumulate in the joints. This condition affects about 25% of the population and can accompany and even worsen osteoarthritis. Chondrocalcinosis is also called pseudogout or pseudo-osteoarthritis, the latter particularly when it affects the knees. A doctor can usually differentiate between the two disorders because chondrocalcinosis usually damages other joints (such as wrists, elbows, and shoulders) that are not normally affected by osteoarthritis.

Charcot’s Joint – Charcot’s joint occurs when an underlying disease, usually diabetes, causes nerve damage in the joint, which leads to swelling, bleeding, increased temperature, and changes in bone. There may be a loss of sensation that leads to an increased risk of injury from overuse.

Lifestyle Changes

Lifestyle changes can help reduce stress on affected joints.

Occupational Changes

Patients with osteoarthritis should reduce shock to the affected joint. Hammering away at deteriorating cartilage may speed up the degeneration. People in occupations with repetitive and stressful movement should find ways to reduce trauma. Adjusting the work area or substituting tasks that produce less stress on joints helps reduce shock.

Exercise

Joints need motion to stay healthy. Long periods of inactivity cause the arthritic joint to stiffen and the adjoining tissue to atrophy (waste away). A moderate exercise program that includes low-impact aerobics and power and strength training has benefits for patients with osteoarthritis, even if exercise does not slow down the disease progression. Exercise helps:

  • Reduce stiffness and increase flexibility. It may also help improve the strength and elasticity of knee cartilage.
  • Promote weight loss.
  • Improve strength, which in turn improves balance and endurance.
  • Reduce stress and improve feelings of well being, which helps patients cope with the emotional burden of pain.

Exercise especially helps patients with mild-to-moderate osteoarthritis in the hip or in the knee. Many patients who begin an aerobic or resistance exercise program report less disability and pain. They are better able to perform daily chores and remain more independent than their inactive peers. Older patients and those with medical problems should always check with their doctor before starting an exercise program.

Three types of exercise are best for people with osteoarthritis

  • Strengthening exercise
  • Range-of-motion exercise
  • Aerobic, or endurance, exercise

Strengthening Exercise – Strengthening exercises include isometric exercises (pushing or pulling against static resistance). Isometric training builds muscle strength while burning fat, helps maintain bone density, and improves digestion. For patients with arthritis in the hip or knees, exercises that strengthen the muscles of the upper leg are important.

Range-of-Motion Exercise  These exercises increase the amount of movement in joints. In general, they are stretching exercises. The best examples are yoga and tai chi, which focus on flexibility, balance, and proper breathing.

Aerobic Exercise Aerobic exercises help control weight and may reduce inflammation in some joints. Low-impact workouts also help stabilize and support the joint. Cycling and walking are beneficial, and swimming or exercising in water is highly recommended, for people with arthritis. (Patients with osteoarthritis should avoid high-impact sports, such as jogging, tennis, and racquetball.)

Physiotherapy

In addition to exercise, treatment of muscles and joints by a trained therapist may be helpful. If patients fail to improve on a home program, a referral to a physical therapist may be beneficial

Weight Reduction

Overweight patients with osteoarthritis can lessen the shock on their joints by losing weight. Knees, for example, sustain an impact three to five times the body weight when descending stairs. Losing 5 pounds of weight can eliminate 20 pounds of stress on the knee. The greater the weight loss, the greater the benefit.

Heat & Ice

Ice – When a joint is inflamed (particularly in the knee) applying ice for 20 – 30 minutes can be helpful. If an ice pack is not available, a package of frozen vegetables works just as well.

Heat Treatments Soaking in a warm bath or applying a heating pad may help relieve pain.

Mechanical aids

A wide variety of devices are available to help support and protect joints. They include splints or braces, and shoe inserts or orthopedic shoes. A commonly used brace for knee osteoarthritis that involves only one side of the knee joint is called an offloading brace.

Treatment of pain

Relaxation techniques such as guided imagery and breathing exercises may help some patients better cope with chronic pain.

Acupuncture & Massage

Some patients use acupuncture to reduce osteoarthritis pain. The technique is painless and involves the insertion of small fine needles at select points in the body. Some studies have found that acupuncture can help provide short-term pain relief.

Transcutaneous electric nerve stimulation (TENS)

Transcutaneous electric nerve stimulation (TENS) uses low-level electrical pulses to suppress pain. A variant (sometimes called percutaneous electrical nerve stimulation, or PENS) applies these pulses through a small needle to acupuncture points. A review of trials reported that both methods were better than placebo (sham treatments) in treating osteoarthritis of the knee, although additional well-designed studies are needed.

Massage therapy may also help provide short-term pain relief. It is important to work with an experienced massage therapist who understands how not to injure sensitive joint areas.

Herbal  and Dietary Supplements

Glucosamine and Chondroitin – Glucosamine hydrochloride and chondroitin sulfate are natural substances that are part of the building blocks found in and around cartilage. For many years, researchers in the U.S. have been studying whether these dietary supplements really work for relieving osteoarthritis pain. Earlier studies indicated a potential benefit from these supplements.

However, several recent high-quality studies involving large numbers of patients have indicated that, in general, glucosamine and chondroitin do not seem to provide any more help than a placebo for the symptoms of osteoarthritis. Some doctors recommend a trial period of three months to see if glucosamine and chondroitin work. If the patient does not experience any benefit, the supplements should be discontinued.

S-adenosylmethionine (SAMe) S-adenosylmethionine (SAMe, pronounced “Sammy”) is a synthetic form of a natural byproduct of the amino acid methionine. It has been marketed as a remedy for arthritis, but scientific evidence supporting these claims is lacking.

Generally, manufacturers of herbal remedies and dietary supplements do not need FDA approval to sell their products. Just like a drug, herbs and supplements can affect the body’s chemistry, and therefore have the potential to produce side effects that may be harmful. There have been several reported cases of serious and even lethal side effects from herbal products. Always check with your doctor before using any herbal remedies or dietary supplements.

Medications

Acetaminophen

Acetaminophen (Tylenol) is the first choice for treating osteoarthritis. (Acetaminophen may be less effective than NSAIDs in reducing moderate-to-severe pain.) Because acetaminophen has fewer side effects, most doctors suggest trying this drug first, then switching to an NSAID if acetaminophen does not provide sufficient pain relief.

Side Effects – Acetaminophen is inexpensive and generally safe. It poses far less of a risk for gastrointestinal problems than NSAIDs.

It does have some adverse effects, however, and the daily dose should not exceed 4 grams (4,000 mg). Patients who take high doses of this drug for long periods are at risk for liver damage, particularly if they drink alcohol and do not eat regularly.

Nonsteroidal anti-inflammatory drugs (NSAIDs)

Nonsteroidal anti-inflammatory drugs (NSAIDs) block prostaglandins, the substances that dilate blood vessels and cause inflammation and pain. There are dozens of NSAIDs available:

  • Over-the-counter NSAIDs NSAIDs include aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve, Naprosyn), ketoprofen (Actron, Orudis KT).
  • Prescription NSAIDs include flurbiprofen (Ansaid), diclofenac (Voltaren, Cataflam), tolmetin (Tolectin), ketoprofen (Orudis, Oruvail), nabumetone (Relafen), dexibuprofen (Seractil), indomethacin (Indocin), meloxicam (Mobic, generic).
  • Topical NSAIDs are gels, creams, or patches that are available either by prescription or over-the-counter. It is not clear how effective they are for osteoarthritis.

Oral NSAIDs should be used only for a short period of time. Long-term use of NSAIDs does not actually delay the progression of osteoarthritis and can increase patients’ risk of side effects.

Patients should use only the lowest effective dose because high dosages of NSAIDs can cause heart problems (such as increased blood pressure and risk of heart attack), kidney problems, and stomach bleeding. Patients who are at increased risk of stomach bleeding and ulcers should either switch to another type of pain reliever, or take the NSAID along with a proton-pump inhibitor drug, such as omeprazole (Prilosec) or esomeprazole (Nexium), or with misoprostol (Cytotec). (Misoprostol can cause miscarriage and should not be used by women who may be pregnant.)

Cox-2 Inhibitors

Coxibs inhibit an inflammation-promoting enzyme called COX-2. This drug class was initially thought to provide benefits equal to NSAIDs but cause less gastrointestinal distress. However, following numerous reports of cardiovascular events, as well as skin rashes and other adverse effects, most COX-2 inhibitors were withdrawn from the market. Celecoxib (Celebrex) is still available, but patients should discuss with their doctors whether this drug is appropriate and safe for them.

Capsaicin

Capsaicin is a component of hot red peppers and may bring pain relief when used as a skin cream (Zostrix). This is the only skin preparation that does more than just mask pain or reduce it temporarily. Capsaicin seems to reduce a substance in the body, known as substance P, which contributes both to inflammation and the delivery of pain impulses from the central nervous system. A small amount of capsaicin must be applied to the area of inflammation about four times a day. During the first few days of use, the patient will experience a warm, stinging sensation when the cream is applied. This sensation goes away, and pain relief usually begins within 1 – 2 weeks.

Tramadol

Tramadol (Ultram) is a pain reliever that has been used as an alternative to opioids. It has opioid-like properties but is not as addictive. (Dependence and abuse have been reported, however.) It can cause nausea but does not cause severe gastrointestinal problems, as NSAIDs can. Some patients experience severe itching. A combination of tramadol and acetaminophen (Ultracet) is available.

Narcotics

Narcotics, pain-relieving and sleep-inducing drugs that act on the central nervous system, are the most powerful medications available for the management of moderate-to-severe pain. There are two types of narcotics:

  • Opiates, which are derived from natural opium (morphine and codeine)
  • Opioids, which are synthetic drugs. They include oxycodone (such as Percodan, Percocet, Roxicodone, and OxyContin), hydrocodone (Vicodin), oxymorphone (Numorphan), and fentanyl (Duragesic)

Although the use of narcotics for arthritic pain is controversial, they may have a place in osteoarthritis treatment when milder drugs are not effective or appropriate. These drugs can be highly addictive, and should be prescribed at the lowest possible effective dose.

Common side effects include anxiety, constipation, nausea and vomiting, dizziness, drowsiness, paranoia, urinary retention, restlessness, and labored or slow breathing.

Corticosteroid injection

When pain becomes a major problem and less potent pain relievers are ineffective, doctors may try corticosteroid (steroid) injections, usually by giving the patient a shot in their joint every 3 months. Corticosteroid shots are useful only if inflammation is present in the joint. Relief from pain and inflammation is of short duration, and this treatment is rarely used for chronic osteoarthritis. These drugs may not be as effective for women as they are for men.

Patients are usually advised not to have more than two or three injections a year, since there is some concern that repeated injections over the long term may be harmful. Because long-term use of corticosteroids has many potentially serious side effects, steroid medications are never given by mouth or systemically for the treatment of osteoarthritis.

Hyaluronic acid injection

Injections of hyaluronic acid (such as Hyalgan, Synvisc, Artzal, and Nuflexxa) into the joint — a procedure called viscosupplementation — may provide pain relief for knee osteoarthritis. Relief usually lasts several months. The most common side effects, pain at the injection site and knee pain and swelling, are usually mild and temporary.

Surgery

Different surgical procedures are available as a final measure to relieve pain and increase function in patients with osteoarthritis. Certain surgical procedures can help relieve pain if medications fail. Even with these procedures, however, joint replacement may still be needed later on.

Arthroscopy and Debridement

Arthroscopy is performed to clean out bone and cartilage fragments (debridement) that, in theory at least, may cause pain and inflammation. It is also sometimes used to diagnose osteoarthritis. In this procedure, the surgeon makes a small incision and inserts the arthroscope, a pencil-sized instrument that contains a light and magnifying lens. The arthroscope is attached to a miniature television camera that allows the surgeon to see the inside of the joint.

Research and debate continue on whether arthroscopy provides true benefits for those with osteoarthritis and, if so, which patients may benefit the most from it. Arthroscopy is most likely to benefit people with mild-to-moderate osteoarthritis who have evidence of bone and cartilage fragments in the joint, or patients whose joints lock or catch with movement.

Joint replacement/Arthroplasty

When osteoarthritis becomes so severe that pain and immobility make normal functioning impossible, many people become candidates for artificial (prosthetic) joint implants using a procedure called arthroplasty. Hip replacement is the most established and successful replacement procedure, followed by knee replacement. Other joint surgeries (such as shoulders, elbows, wrists, and fingers) are less common, and some arthritic joints (in the spine, for instance) cannot yet be treated in this manner. When two joints, such as both knees, need to be replaced, having the operations done sequentially rather than at the same time may result in fewer complications.

Candidates  The primary indications for surgery are pain and significant limitations of movement, including walking, that cannot be treated by less invasive therapies.

Patients who may not be good candidates are those with the following conditions:

  • Severe neurologic, emotional, or mental disorders
  • Severe osteoporosis
  • Other chronic medical conditions
  • Obesity

Surgeons often prefer to delay prosthetic implantation in younger patients, because implants wear out and the patient will need at least one revision procedure later on. Newer, longer-lasting materials, however, may help reduce the rate of revision operations.

Elderly patients with poorly controlled osteoarthritis often do very well after joint replacement surgery. While full recovery may take older patients longer than younger people, the long-term outcome of the surgery is excellent, and leads to significant improvements in pain and quality of life.

Complications  Complications can occur, and, although uncommon, some can be life threatening. In addition to blood loss and infection, deep blood clots in the legs (deep venous thrombosis) are a serious potential complication. These clots can potentially travel to the lungs (pulmonary embolism) and pose a risk for death. Patients who are overweight are at higher than average risk for blood clots.

Recovery and Rehabilitation  Aside from the surgeon’s skill and the patient’s underlying condition, the success rate depends on the kind and degree of activity the joint receives following replacement surgery. Physical therapy takes about 6 weeks to rebuild adjoining muscle and strengthen surrounding ligaments. Patients typically experience considerable pain during this time.

While many patients find that joint replacement eventually provides pain relief and restores some mobility, they need time to adjust to the artificial joint.

Limitations after hip surgery include

  • Usually patients with new hips are able to walk several miles a day and climb stairs, but they cannot run.
  • Prosthetic hips should not be flexed beyond 90 degrees, so patients must learn new ways to perform activities requiring bending down (like tying a shoe).

Limitations after knee surgery include

  • Walking distance improves in 80% of patients after knee replacement surgery, but patients still cannot run.
  • Only slightly more than half of patients report improvement in stair climbing. (Artificial knee joints generally have a range of motion of just 110 degrees.)

Minimally Invasive Arthroplasty – Surgeons are exploring a variety of new techniques for a “minimally invasive” approach to knee and hip arthroplasty. They include using a shorter incision, and new types of smaller specialized instruments. The goal is to give the patient a shorter recovery time and less postoperative pain. However, minimally invasive arthroplasty is still in its early stages. At this time, there is no consensus on which minimally invasive technique works best, or if it actually achieves any additional benefits beyond the recovery period.

Unicompartmental Knee Arthroplasty Unicompartmental knee arthroplasty (also called unicondylar knee arthroplasty) may be a useful procedure in cases of limited knee damage. It is recommended for relatively sedentary patients who are 60 years or older and not obese. It may relieve pain and delay the need for a total knee replacement. The procedure involves a small incision and insertion of small implants. It retains important knee ligaments, which preserve more movement than a total knee replacement.

Hip Resurfacing  Hip resurfacing is a surgical alternative to total hip replacement. It involves scraping the surfaces of the hip joint and femur and placing a metal cap over the bone. The procedure preserves much of the bone, so that a standard hip replacement can be done years later if needed. It may provide more stability, a faster recovery, and greater range of motion, making it a potentially good option for young, physically active patients.

Revision Arthroplasty  A repair procedure called arthroplasty revision may be used in cases where the original transplant fails. The specific procedure depends on whether the bone defects that occurred are contained or uncontained.

  • Contained defects can be repaired with small bone grafts, the use of cement, or oversized cementless implants as required.
  • Uncontained defects are more severe and may require a large bone graft or specially constructed implants to restore bone.

If a second arthroplasty is required, the potential for complications is magnified: more bone is cut, more blood is lost, and the operation takes longer. Patients are also generally older and more vulnerable to complications.

REALIGNING BONES (OSTEOTOMY)

Osteotomy is a surgical procedure used to realign bone and cartilage and reposition the joint. If only a certain section (the medial compartment) of the knee is damaged and deformed by osteoarthritis, the surgeon may choose to perform an osteotomy:

  • The surgeon opens the knee.
  • The surgeon performs a debridement (removal of damaged tissue) in the joint to eliminate the loose or torn fragments that are causing pain and inflammation.
  • The bone is then reshaped to remove the deformity.
  • The procedure may ease symptoms and slow disease progression. It is best used in heavier adults who are under 60 years old.

Hemicallotasis. Hemicallotasis is a procedure for the knee that may be a less invasive alternative to osteotomy. The surgeon attaches the knee with pins to an external frame-like device that lengthens the deformed part of the knee over several weeks. The patient is mobile during this period. Infections at the pin site are the most common complications.

FUSING BONES (ARTHRODESIS)

If the affected joint cannot be replaced, surgeons can perform a procedure called arthrodesis that eliminates pain by fusing the bones together. The patient must understand, however, that fusing the bones makes the movement of the joint impossible. Bone fusion is most often done in the spine and in the small joints of the hands and feet.
