What is Osteoarthritis (OA) Knee?

Osteoarthritis knee is one of the most common type of arthritis in Singapore. Osteoarthritis knee develops mainly due to degeneration and overuse of knees. It could also be due to repetitive strain injury (RCI). Degeneration occurs when the covering at the bones in the knee underwent wear and tear gradually, resulting in painful bone on bone rubbing and disrupted movement. Deformity is a late stage of the osteoarthritis knee condition and is irreversible.
