The anterolateral approach in the supine position provides excellent visualization of the acetabulum. The main advantage of
the approach, a low dislocation rate, has been demonstrated in the literature, while the purported disadvantage of abductor
dysfunction has not been clearly delineated in the literature. The technique requires meticulous attention to preservation
of the gluteus medius and minimus tendons. Impingement and dislocation are avoided by careful attention to the preparation
of acetabulum, critical assessment of the implanted components, and intraoperative trialing. Leg lengths are assessed through
direct palpation of the malleoli. Routine use of postoperative hip precautions is not necessary when this approach is utilized.
The anterolateral approach in the supine position allows for a reproducible result with a low dislocation rate.
