Knee replacement surgery is usually undertaken when osteoarthritis has resulted in the wearing down of the knee joint. In a knee replacement operation the worn out and arthritic parts of the knee joint are removed and replaced with a new, artificial knee joint. The new knee joint is called a prosthesis. More recently, Computer Guided Total Knee Replacements as well as a new technological development called “patient specific instrumentation” or a “custom fit knee” is beeing performed.
