Knee replacement surgery, also known as knee arthroplasty, replaces joints in the knee that are damaged or worn. Total knee replacement surgery is a procedure in which damaged cartilage and bones of the knee are removed and replaced with artificial metal joints and plastic spacers. Depending on the extent of the damage to the knee, the kneecap may also be resurfaced and covered with a protective plastic button.
