Knee replacement surgery is also termed knee arthroplasty which is a surgical procedure that requires resurfacing of the bones. Basic steps for a knee replacement surgery include

Resurfacing the patella- The knee cap is also known as the patella. The undersurface of it is cut and replaced with a plastic button. In many cases, resurfacing of the knee cap is not required.
