A hip resurfacing is a procedure designed to treat hip arthritis by removing the least amount of bone possible. The hip joint is opened through an incision on the side of the hip. The damaged surfaces of the joint are surgically removed. The joint is then resurfaced with metal parts. The parts are pressed into the socket of the joint (the acetabulum) and cemented onto the ball of the joint (the femoral head). This surgery can only be performed safely on a small number of patients. Not every patient qualifies for a hip resurfacing. The surgery may be performed with a computer navigation system. You are allowed to walk immediately after surgery. The surgery can be performed as an outpatient, or it may require a very short hospital stay.
