This less invasive surgery for hip replacement allows exposure from the front of the hip joint as opposed to the side (lateral) or to the back (posterior). In the anterior approach, the hip is replaced through a natural interval between muscles. The important muscles for hip function, the gluteal muscles that attach to the posterior and lateral pelvis and femur, are left undisturbed.

Lack of disturbance of the lateral and posterior soft tissues also accounts for immediate stability of the hip and low risk of dislocation. It is normal for patients undergoing posterior incisions to follow strict precautions that limit hip motion for the first two months after surgery. Most importantly, they are instructed to limit hip flexion to no more than 60 degrees. These limitations complicate a patient's simple daily activities such as sitting in a chair or on the toilet or just getting in a car.

Following the anterior approach, however, patients are immediately allowed to bend their hip freely and to avoid these cumbersome restrictions. Additionally, if patients are sexually active before surgery, there are no limitations on resumption of normal sexual activity after surgery.

The anterior approach for total hip replacement is less invasive, is easier on the tissues and allows the procedure to be performed through a smaller soft tissue "window." With this approach, muscles are not cut. Instead, they are separated naturally which results in a far quicker recovery period and far less activity restrictions than traditional hip replacement surgery.

The payoff for patients is far less pain and a much faster recovery.
