Knee inflammation can have many causes, including injury, arthritis, infection, gout and bursitis.
Minor inflammation can usually be treated at home. Ice, elevation and resting your knee may resolve the problem. Exercise or physiotherapy may also help. Your GP may prescribe non-steroidal anti-inflammatory agents (NSAIDs) such as ibuprofen or naproxen to reduce the inflammation.
In cases of continued or increasing pain your GP may refer you to an orthopaedic specialist for diagnosis and treatment.
