Direct Anterior Hip Replacement Surgery
Potential for less pain, faster recovery and improved mobility
The Anterior Approach for total hip replacement is a tissue-sparing alternative to traditional hip replacement surgery that provides the potential for less pain, faster recovery and improved mobility because the muscle tissues are spared during the surgical procedure. The technique allows the surgeon to work between the patient?s muscles and tissues without detaching them from either the hip or thighbones?sparing the tissue from trauma.
Keeping the muscles intact may also help to prevent dislocations. With the Anterior Approach, the surgeon uses one small incision on the front (anterior) of your hip as opposed to the side or back. Since the incision is in front, the patient avoids the pain of sitting on the incision site.
Anterior Approach Incision
The Anterior Approach procedure for total hip replacement has been gaining popularity recently due to its potential benefits:
Possible accelerated recovery time because key muscles are not detached during the operation. (Some other procedures require cutting or disturbing the important muscles at the side or back of the leg.) The Anterior Approach is known as a tissue-sparing procedure because it avoids cutting these key muscles and tissues and therefore minimizes muscle damage.
Potential for fewer restrictions during recovery. Although each patient responds differently, this procedure seeks to help patients more freely bend their hip and bear their full weight immediately or soon after surgery.
Possible reduced scarring because the technique allows for one relatively small incision. Potential for stability of the implant sooner after the surgery, resulting in part from the fact that the key muscles and tissues are not disturbed during the operation.
The Anterior Approach differs in multiple ways from other surgery techniques:
The hip is exposed in a way that does not detach muscles or tendons from the bone. A high-tech operating table is often used to help improve access Intraoperative x-ray or computer navigation is typically used to confirm implant position and leg length.
Larger, heavier patients may be candidates for minimally invasive hip surgery with this technique. The Anterior Approach enters the body closer to the hip joint, with far less tissue between the skin and the bones of the hip, so more patients may be candidates.
Every surgical approach has risks and benefits. The way a hip replacement will perform depends on age, weight, activity level and other factors. There are potential risks and recovery takes time. If patients have conditions that limit rehabilitation, they should not have this surgery. Only an orthopaedic surgeon can tell a patient if hip replacement is right for them.
Patients' doctors will tell them what restrictions they will have after surgery. Every surgeon has his or her own set of precautions for their patients to follow.
