Knee osteoarthritis is a common cause of knee pain that usually begins in middle age. It is a progressive degeneration of the joint due to overuse or a previous injury.
Signs & symptoms:

A knee replacement surgery may be required but physiotherapy involving strengthening of the muscles surrounding the knees, increase joint range of motion and reducing pain until such time as surgery is required.
