Osteoarthritis

Explore the available health information, treatment context, and integrative evidence for Osteoarthritis.

Background
  • Osteoarthritis (OA), also called degenerative joint disease (DJD) or osteoarthrosis, occurs when the cartilage in the joints begins to break down. The cartilage serves as a cushion between bones, allowing the joint to move without pain. Therefore, individuals with osteoarthritis experience pain and reduced mobility in their joints where cartilage is degrading. Osteoarthritis may affect any joint in the body.
  • The term arthritis literally means joint inflammation or swelling. More than 100 different disease fall under the general category of arthritis. Arthritis conditions affect the joints, the tissues surrounding the affected joints, and other connective tissues. Common forms of arthritis include rheumatoid arthritis, osteoarthritis, and periarthritis.
  • As the disease progresses, crevices and bone spurs, called oseophytes, may develop within the affected joint, increasing pain and decreasing mobility.
  • According to the Arthritis Foundation, more than 20 million Americans and 70-90% of persons older than 75 years are affected by osteoarthritis. Although symptoms of osteoarthritis occur earlier in women (around the ages of 50-55), the prevalence among men and women is equal in older ages. In addition to age, risk factors include joint injury, obesity, and mechanical stress (such as joint stress when pitching a baseball or playing tennis).
Signs and Symptoms
  • Because osteoarthritis develops slowly, many individuals do not experience symptoms until several years after cartilage breakdown begins. Common symptoms include joint pain, swelling and/or stiffness in a joint (especially after use), joint discomfort before or during a change in the weather, bony lumps on the fingers, and loss of joint flexibility. The joints that are most often affected by osteoarthritis include the fingers, spine, and weight-bearing joints, such as the hips, ankles, feet, and knees. Stiffness in the joint may occur after inactivity, such as upon rising in the morning or after a long car ride.
  • Once symptoms develop, they are generally the worst during the first year of the disease. Pain often is described as a deep ache and is confined to the affected joint, called localized pain. In most cases, pain increases with use of the joint and subsides with rest. However, as the disease progresses, pain may become persistent. Osteoarthritis may cause pain at night that interferes with sleep.
  • If individuals overuse the affected joints and do not receive treatment, the cartilage in the joints may wear down completely. When this happens, the bone may rub against bone, causing severe pain and joint damage.
Diagnosis
  • General: Once individuals are diagnosed with osteoarthritis, they should visit their healthcare providers regularly, at least once a year. Individuals should stay in close contact with their doctors to ensure that their symptoms are managed and joint damage is monitored
  • X-ray: X-rays are often the first test performed if a patient has symptoms of osteoarthritis. If the patient has osteoarthritis, the x-ray images will often show loss of cartilage in the affected joints, narrowing of the space between bones, and bumps called nodules.
  • Arthrocentesis: A procedure called arthrocentesis may also be performed at a healthcare provider's office. During the procedure, a needle is inserted into the affected joint, and a small sample of fluid is removed. The fluid is then analyzed to rule out other conditions, such as gout or infection. This test may also temporarily relieve some pain and inflammation in the joint.
  • Arthroscopy: A surgical procedure called arthroscopy may also be performed. During the surgery, a small incision is made into the affected joint. Then a tube called an arthroscope is inserted into the joint. This tube has a small light and camera, which allows the healthcare provider to see the inside of the joint. If abnormalities, including cartilage or ligament damage are seen, the individual is diagnosed with osteoarthritis.
Complications
  • Cosmetic concerns: Osteoarthritis may cause small bumps, called nodules, to form on bones. These bumps can occur on any joint, but they are most common in the hands. These nodules may be disfiguring and painful in some individuals.
  • Depression: Some osteoarthritis patients may suffer from depression. This may happen if the arthritis interferes significantly with the patient's lifestyle. Individuals should consult their healthcare providers if they experience feelings of sadness, low self-esteem, loss of pleasure, apathy, and sometimes, difficulty functioning for two weeks or longer, with no known underlying cause. These may be signs of depression.
  • Joint damage: In some cases, osteoarthritis can lead to severe joint damage. In such cases, surgery, such as a joint replacement, may be necessary. Individuals should have annual checkups with their healthcare providers to monitor health conditions.
  • Limited mobility: Patients with arthritis may have limited mobility in the joints, such as limited movement of the knee or shoulder. Joint mobility decreases as the joint becomes more damaged. If osteoarthritis is not properly managed with medications such as steroids and nonsteroidal anti-inflammatory drugs (NSAIDs) or surgery, arthritis may interfere with the individual's daily life.
  • Pain: Osteoarthritis may cause severe pain. Individuals should stay in close contact with their healthcare providers to ensure that their medications are properly managing the pain. In some cases, the medication or dosage may need to be changed.
Treatment
  • General: Osteoarthritis is managed with medications that reduce pain and inflammation. In severe cases, surgery may be necessary to repair damage.
  • In order to properly manage pain and prevent joint damage, individuals should take their medications exactly as prescribed by their healthcare providers. Individuals with osteoarthritis should also tell their healthcare providers if they are taking any other drugs (prescription, over-the-counter, or dietary supplements) because they may interfere with treatment.
  • Antidepressants: Some individuals with arthritis may also suffer from depression. Commonly prescribed anti-depressants for arthritis patients include the tricyclic antidepressants amitriptyline (Elavil®), nortriptyline (Aventyl®, Pamelor®), and trazodone (Desyrel®). Side effects of tricyclic antidepressant medications include drowsiness, fatigue (excessive tiredness), constipation, dry mouth, and blurred vision.
  • Arthroscopic lavage and/or debridement: In some cases, individuals with osteoarthritis may suffer from severe joint damage. In such cases, surgical procedures called arthroscopic lavage and/or arthroscopic debridement may be recommended. During the surgery, a small incision is made near the joint. A small tubular instrument called an arthroscope is then inserted. The arthroscope has a small light and camera attached to it, allowing the surgeon to see inside the joint. During arthroscopic lavage, the surgeon squirts saline into the joint. The saline is then removed along with any blood, fluid, or loose debris inside the joint. During arthroscopic debridement, loose fragments of bone or cartilage are removed from the joint. In some cases, built up scar tissue may also be removed.
  • Both of these procedures may provide temporary pain relief and improved joint function. However, recent studies suggest that they may not be effective in some individuals with osteoarthritis. Therefore, individuals should discuss the potential risks and health benefits of the procedure with their healthcare providers.
  • Corticosteroids: Corticosteroids, such as prednisone (e.g. Deltasone®) and methylprednisolone (Medrol®), are occasionally used to reduce inflammation and pain and slow joint damage caused by osteoarthritis. These drugs are generally very effective when used short-term (weeks to a few months). However, if these drugs are used for six months or longer, they may become less effective and serious side effects may develop. Side effects may include easy bruising, thinning of bones, cataracts, weight gain, a round face, and diabetes.
  • Corticosteroids are usually prescribed for a certain amount of time, and then the individual is gradually tapered off the medication. Individuals should not stop taking corticosteroids suddenly or change their dosages without first consulting their healthcare providers.
  • Cool compress or ice pack: Applying a cool compress or ice pack to the affected joint may help reduce swelling and pain.
  • Heat: Applying a hot pack to affected joints may help reduce pain, relax muscles, and increase blood flow to the joint. It may also be an effective treatment before exercise. Alternatively, individuals may take a hot shower or bath before exercise to help reduce pain.
  • Fusing bones: If there is serious joint damage, the bones of a joint, such as the ankle, may be surgically fused together in a procedure called arthrodesis. This surgery helps increase stability and reduces pain. Although the joint may be pain-free after bone fusing, the joint no longer has any flexibility and cannot bend or move, which may limit an individual's ability to move around easily.
  • Joint replacement surgery: In some cases, individuals with osteoarthritis suffer from permanent joint damage. In such instances, joint replacement surgery may be necessary. During the procedure, the damaged joint is surgically removed, and it is replaced with a plastic or metal device called a prosthesis. The most commonly replaced joints are the hip and knee, but other joints, including the elbow, shoulder, finger, or ankle joints, can be replaced.
  • Joint replacement surgeries are generally most successful for large joints, such as the hip or knee. Researchers estimate that hip or knee replacements last at least 20 years in 80% of patients. After a successful surgery and several months of rehabilitation, individuals are able to use their new joints without pain.
  • As with any major surgery, there are risks associated with joint replacements. Patients should discuss the potential health risks and benefits of surgery with their healthcare providers.
  • Lifestyle adjustments: Many lifestyle changes, including regular exercise, weight management, and healthy diet, may help reduce symptoms of osteoarthritis. A healthcare provider may recommend a physical therapist or nutritionist to help determine the best treatment plan for the individual. Healthcare professionals recommend removing inflammatory foods from the diet, including dairy products, wheat, and nightshade plants (such as potatoes, peppers, eggplant, tomatoes, and tobacco). Patients should also remove or decrease consumption of all animal products other than fish and, if possible, eat a raw food vegetarian diet (vegetarian plus elimination of all animal products, especially dairy). Besides green vegetables, the diet should include: carrots, avocado, sea weeds, spirulina, soy products, whole grains (such as brown rice, millet, oats, wheat, and barley), seeds (sesame, flax, and pumpkin), and cold-water fish (such as salmon, herring, and tuna). It is best to avoid the following foods: alcohol, coffee, refined sugars, saturated fat, hydrogenated fat (margarine), excess salt, spinach, cranberries, plums, buckwheat, and nuts.
  • Individuals with osteoarthritis should wear comfortable footwear that properly supports their weight. This may reduce the amount of strain put on the joints during walking.
  • Individuals with osteoarthritis may require canes, walkers, or other devices to help them get around. If the hands are severely affected, braces may be beneficial. Individuals should talk to their healthcare providers about assistive devices that are available.
  • Individuals with osteoarthritis or rheumatoid arthritis should maintain good posture. This allows the body's weight to be evenly distributed among joints.
  • Non-selective Nonsteroidal anti-inflammatory drugs (NSAIDs): Nonsteroidal anti-inflammatory drugs (NSAIDs) have been used to relieve pain and inflammation caused by osteoarthritis. Commonly used over-the-counter NSAIDs include ibuprofen (Advil® or Motrin®) and naproxen sodium (Aleve®). Higher doses of these drugs are also available by prescription. Commonly prescribed NSAIDs include diclofenac (Cataflam® or Voltaren®), nabumetone (Relafen®), and ketoprofen (Orudis®). NSAIDs may be taken by mouth, injected into a vein, or applied to the skin. These medications are generally taken long term to manage symptoms.
  • The frequency and severity of side effects vary with NSAIDs. The most common side effects include nausea, vomiting, diarrhea, constipation, decreased appetite, rash, dizziness, headache, and drowsiness. The most serious side effects include kidney failure, liver failure, ulcers, heart-related problems, and prolonged bleeding after an injury or surgery. About 15% of patients who receive long-term NSAID treatment develop ulcers in the stomach or duodenum.
  • Pain relievers: Prescription pain relievers, including tramadol (Ultram®), have been used to reduce pain caused by osteoarthritis. Although this drug, which is available by prescription, does not reduce swelling, it has fewer side effects than NSAIDs. Tramadol is generally taken as a short-term treatment to reduce symptoms of flare-ups.
  • Narcotic pain relievers, such as acetaminophen/codeine (Tylenol with Codeine®), hydrocodone/acetaminophen (Lorcet®, Lortab®, or Vicodin®), or oxycodone (OxyContin® or Roxicodone®), may be prescribed to treat severe arthritis pain. However, they do not reduce swelling. These medications are only used short-term to treat flare-ups. Common side effects include constipation, drowsiness, dry mouth, and difficulty urinating. Narcotic pain relievers should be used cautiously because individuals may become addicted to them.
  • Selective COX-2 inhibitors: Celecoxib (Celebrex®) has been taken by mouth to reduce pain and inflammation caused by osteoarthritis. Celecoxib is currently the only COX-2 inhibitor that is approved by the U.S. Food and Drug Administration (FDA). Celecoxib is generally taken long term to manage symptoms.
  • COX-2 inhibitors have been linked to an increased risk of serious heart-related side effects, including heart attack and stroke. Selective COX-2 inhibitors have also been shown to increase the risk of stomach bleeding, fluid retention, kidney problems, and liver damage. Less serious side effects may include headache, indigestion, upper respiratory tract infection, diarrhea, sinus inflammation, stomach pain, and nausea.
  • Topical pain relievers: Topical pain relievers are creams, ointments, gels, and sprays that are applied to the skin. Many over-the-counter (OTC) pain relievers may temporarily help reduce the pain caused by osteoarthritis. Products such as Aspercreme®, Sportscreme®, Icy Hot®, and Ben-Gay® may help reduce arthritis pain. Capsaicin cream, which is made from the seeds of hot peppers, may reduce pain in joints that are close to the skin surface, such as the fingers, knees, and elbows. Healthcare providers recommend using capsaicin creams for at least seven to 14 days, as the effects may take time to be seen. The initial burning pain of the hot pepper usually subsides after a few days.
Prevention
  • Individuals who maintain a healthy body weight have a decreased risk of developing osteoarthritis. Eating a healthy and well-balanced diet may help individuals control their weight. The U.S. government issued a revised food pyramid in 2005 in an effort to help Americans live healthier. The new pyramid provides 12 different models, which are based on daily calorie needs, ranging from the 1,000-calorie diets for toddlers to 3,200-calorie diets for teenage boys.
  • Regular exercise may also help individuals control their weight. There are many ways for people to exercise including: gardening, walking, sports activities, and dancing. Individuals who are beginning an exercise program should choose activities that fit their levels of strength and endurance. The type of exercise is not as important as a consistent exercise schedule. Most experts today agree that burning calories should not be the goal of exercise. Exercise that causes extreme pain or discomfort is considered by many experts as unhealthy, and may even cause permanent damage to the body.
