The anterior approach surgery procedure is a technique that minimizes the pain and time from surgery to recovery. The anterior approach allows the surgeon to reach the hip joint from the front of the hip as opposed to the lateral (side), or the posterior (back) approach, both of which can cause significant muscular damage. With the anterior approach the hip can be replaced without detachment of muscle from the pelvis or femur during surgery. By way of this anterior approach the surgeon can simply work through the natural interval between the muscles, rather than detaching them. In this way the gluteal muscles that attach to the pelvis and femur are left undisturbed in the anterior approach. Therefore, these muscles do not require a healing process after the surgery.
