Drugs such as salicylates (aspirin) and nonsteroidal anti-inflammatory drugs (NSAIDs) are used to relieve pain and reduce inflammation. 

Steroids, which are injected directly into the joint, may also be used. 

Steroids may also be given orally to patients with rheumatoid arthritis, but not to those with osteoarthritis.

Good nutrition and careful weight control are important, especially for patients who are overweight.

Hot and cold treatments ,ultrasound treatments and particularly Short wave diathermy (SWD) are used to relieve pain and improve joint flexibility.

Exercises are prescribed to strengthen the muscles and tissues supporting the joint and to maintain as much joint motion as possible.

The use of crutches, canes, or walkers may be prescribed to protect the joints from stress. Splints are also used to maintain proper joint positions.

Learning less stressful ways to accomplish daily activities and home management are part of the treatment process.

The most common surgical treatment for osteoarthritis is total joint replacement. 

Hip joints are the most commonly and successfully replaced joints, but the elbow, shoulder, knee, and ankle joints can also be replaced. 

With rheumatoid arthritis, the first surgical treatment is removal of the synovium; total joint replacement is a later alternative.

Arthroplasty  the surgical reconstruction or replacement of a painful, broken-down joint.
