Osteoarthritis is a progressive, degenerative joint disease characterized by chronic inflammation of the joint lining. People with osteoarthritis usually have joint pain and limited movement of the affected joint.

Healthy cartilage is a cushion between the bones in a joint. With osteoarthritis, the cartilage wears away over a long period of time, causing bones to rub together. The exact cause is unclear, but it may be a combination of genetics and environment.
Factors that may increase your chance of osteoarthritis include:
- Increasing age
- Excess body weight—risk of osteoporosis increases with increasing body weight
- Family history of osteoarthritis
Certain endocrine, metabolic, or neuropathic disorders,
- Having an injury or surgery to the joint surface, especially the cartilage
- Having an occupation or doing physical activities that put stress on joints
Osteoarthritis usually affects the hands, feet, spine, hips, and knees. Common symptoms include:
- Mild-to-severe pain in a joint, especially after overuse or long periods of inactivity, such as sitting for a long time
- Creaking or grating sound in the joint
- Swelling, stiffness, limited movement of the joint, especially in the morning
- Deformity of the joint
Your doctor will ask about your symptoms and medical history. A physical exam will be done.
Tests may include:
to evaluate bones and joints
- CT scan
to look at the extent of the arthritis
to rule out other causes of arthritis
- Blood tests to rule out other causes of arthritis
There is no treatment that stops cartilage loss or repairs damaged cartilage or bones of the joint. When cartilage wears away, bone on bone friction causes pain and inflammation. The goal of treatment is to reduce joint pain and inflammation, and to improve joint function.
Options may include:
can lessen the stress on joints affected by osteoarthritis. The more weight lost, the greater the benefit.
Consider talking to a dietitian who can help you with meal planning.
Strengthening the muscles supporting an arthritic joint (particularly the knee, lower back, and neck) may decrease pain and absorb energy around the joint. For example, if you have arthritis in the knee, exercise and
can also help improve knee function.
Swimming and water aerobics are good options. They do not put stress on the joint.
Another option is transcutaneous electrical nerve stimulation (TENS). With TENS, you are connected to a machine. The machine sends electrical signals through the skin to nerves. This type of therapy may decrease pain in some people.
If you have knee osteoarthritis, manual therapy, including
and manipulation, may be helpful.
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
- Cyclooxgenase-2 (COX-2) inhibitors
- Topical pain medications that are applied to the skin
- Opioids and similar medications
- Viscosupplementation injection
- Corticosteroid injection
Applying heat with hot water bottles, warm soaks, paraffin, or heating pads helps joints and muscles move more easily. It can also lessen pain. Using ice packs after activity can also help.
are two commonly used supplements. But, research has shown that these are not beneficial for most people with osteoarthritis. Talk with your doctor before taking any herbs or supplements.
Shoes with shock-absorbing
soles may provide some relief while you are doing daily activities or exercising. Splints or braces help to properly align joints and distribute weight. Knee and wrist joints may benefit from elastic supports.
walkers, and orthopedic shoes can help with advanced osteoarthritis in the lower body.
If you are having difficulty getting around due to arthritis pain, your doctor might recommend that you install handrails and grips throughout your home. These are useful in the bathroom and shower. You may need elevated seats, including
toilet seats, if you're having difficulty rising after sitting.
Surgery may be needed for joints with severe damage. It may be done to remove loose pieces of bone or cartilage from joints or reposition bones to redistribute stress on the joint. Some may need to have the joint replaced with an artificial joint.
To help reduce your chance of osteoarthritis:
- Maintain a healthy weight.
- Do regular, gentle exercise, such as walking, stretching, swimming, or yoga.
- Avoid repetitive motions and risky activities that may contribute to joint injury, especially after age 40.
- With advancing age, certain activities may have to be stopped or modified. It is important to continue to be active, so find an activity that suits you.
