In most of the medical cases related to knee damage, the surgeon usually suggests a minimally invasive total knee surgery. The only difference is that the surgery is done by making a small incision and within a smaller surgical area than in the traditional knee replacement surgery. The surgery requires only a small incision of 3 to 6 inches as against the 8 to 122 inch cut in the traditional method. In the minimally invasive surgery, a surgeon just pushes the kneecap aside whereas in the traditional surgery, knee is turned over 180 degrees so that surgery could be performed easily. The only risk involved during the minimally invasive knee replacement surgery is that the surgeon has limited access to the knee joint and that may increase the complications during the surgery.
