Knee Replacement.

Total Knee Replacement (pronunciation: /ˈtoʊtəl niː rɪˈpleɪsmənt/), also known as Total Knee Arthroplasty (pronunciation: /ˈtoʊtəl niː ɑːrˈθrɒpləsi/), 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, and also for other knee diseases such as rheumatoid arthritis and psoriatic arthritis.

Etymology

The term "Total Knee Replacement" originates from the English words "total" (meaning whole or entire), "knee" (the joint between the thigh and the lower leg in humans), and "replacement" (meaning to take the place of). The term "Arthroplasty" comes from Greek words "arthro-" (joint) and "-plasty" (formation).

Procedure

In Total Knee Replacement, the damaged cartilage and bone from the surface of the knee joint is removed and replaced with artificial components made of metal and high-grade plastics. The procedure is performed under anesthesia.
