Knee Replacement, Total
A total knee replacement (arthroplasty) is a surgical procedure in which the articular surfaces of the tibia, femur, and patella are replaced with prosthetic devices. It is performed to relieve joint pain that has not been controlled by conservative management and/or improve joint mobility in persons with severe arthritis, congenital knee deformity, hemophilic arthropathy, or severe intraarticular injury.
There are a variety of prostheses available. The type most frequently used is the tricompartmental prostheses that has separate femoral, tibial, and patellar components. Fixation of the prostheses is accomplished by using a cement-like agent called polymethylmethacrylate or, if left uncemented, by bone ingrowth into the porous outer surface on the prostheses.
