At the Surgical centre, the worn-out joint is replaced by using anterior approach, which means a 15 cm (3 in.) long incision is made on the front of the knee. The surgeon then removes the damaged surfaces of the joint and resurfaces the knee with the prosthesis (a U-shaped femoral component and a flat tibial plateau). Bone cement is used to anchor the joint, which enables the patient to place full weight on the operated knee immediately after the surgery, and allows for quick recovery. There is very little post-operative bleeding. Blood transfusion is normally not needed. Directly after the surgery, the patient should start doing passive rehabilitation exercises on Kinetec (an exercise device enhancing joint mobility) along with active exercises. On the fourth post-operative day, you can start walking up and down stairs, and on the fifth day you can check out from hospital.
