Knee Arthritis

There are many different forms of arthritis, but the most common types are Osteoarthritis and Rheumatoid Arthritis.

Osteoarthritis is caused when the knee joint and the cartilage start to wear away and over time the pain becomes worse as the cartilage separating the bones disappears and bone begins to rub on bone.

Rheumatoid Arthritis affects the synovial membrane that encloses the knee joint. If you are suffering from rheumatoid arthritis, the synovial membrane swells up and causes stiffness and pain. Surgical solutions include arthroscopy, cartilage grafting, total or partial knee replacement, osteotomy or synovectomy.
