What is a total knee replacement?

A knee replacement, also known as knee arthroplasty, is a surgical procedure to replace the damaged or worn surfaces of the knee joint with artificial components. This procedure is typically performed to relieve pain and improve function in individuals with severe knee arthritis or other conditions that affect the knee joint, such as injury or deformity. During the surgery, the damaged parts of the knee joint are removed and replaced with metal and plastic implants designed to replicate the natural movement of the knee.
