Arthroplasty, knee, condyle and plateau; medial and lateral compartments with or without patella resurfacing (total knee arthroplasty)

AI EXPLANATION: Total knee replacement, or total knee arthroplasty, is an operation to rebuild a severely worn or damaged knee joint. During the procedure, an orthopedic surgeon removes damaged bone and cartilage from the lower end of the thighbone and the upper end of the shinbone, and sometimes resurfaces the underside of the kneecap. The removed tissue is replaced with durable metal and specialized plastic components designed to recreate the smooth gliding surfaces of a healthy knee.
