Knee

A total knee replacement (also called total knee arthroplasty) is a surgical procedure in which a damaged or worn knee joint is replaced with artificial components. The knee joint surfaces at the end of the thigh bone (femur), top of the shin bone (tibia), and sometimes the underside of the kneecap (patella) are resurfaced with metal and plastic components.
The goal of knee replacement surgery is to relieve pain, improve mobility, and restore function when non-surgical treatments are no longer effective.
