Total knee replacement removes damaged cartilage and bone from the knee joint and replaces it with an artificial implant, relieving pain and restoring function for patients with severe arthritis or joint damage. It is one of the most successful orthopedic procedures, helping patients return to daily activities with significantly reduced pain.
Knee replacement is generally recommended when arthritis or joint damage causes significant pain and disability that has not improved with medication, physiotherapy, or injections, and when X-rays show substantial cartilage loss.
