Frequently Asked Questions |
Arthritis in the knee joint occurs as a result of degeneration of the cartilage in the knee. Osteoarthritis is commonly referred to as “wear- and-tear” arthritis or degenerative arthritis, and may manifest itself as a stiff, painful joint that may occasionally “lock” or “give way” during walking. In osteoarthritis, the cartilage in the knee breaks down over time and the result is a severely damaged joint surface with bone rubbing on bone. This process may occur as a result of previous trauma to the joint, ligament instability, or abnormal stresses to the joint. Rheumatoid arthritis is an inflammatory process that results in erosion of the articular cartilage and subsequent damage to the knee joint surface. Uni-compartmental knee replacement is not indicated in cases of rheumatoid arthritis.
