Knee replacement. Knee replacement, also known as knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability. It is most commonly performed for osteoarthritis,[1] and also for other knee diseases such as rheumatoid arthritis and psoriatic arthritis.
These terms refer to the portion of the replacement that is attached to the tibia. When fixed-bearing implants are used, a metal component is inserted into the tibia and a polyethylene (plastic) tray is locked into place on top of it.ip and Knee Implants With a history of excellent surgical technique and outcomes, the focus of new development in this area is on the use of enabling technology to improve preparation and component positioning in hip and knee replacement surgery.
