Anterior Hip Replacement offers a faster recovery time with few if any mobility restrictions immediately after surgery.
Using a specially-designed surgical table, the surgeon is able to reach and replace the hip joint from the front of the hip with a small incision, as opposed to the side or back of the hip (posterior) with a larger incision. The gluteal muscles, which are the three muscles that attach to the pelvis and femur and make up the buttocks and the most important muscles for hip function, are left undisturbed and do not require healing. Additionally, dislocation risks can be reduced with this approach and leg length is more accurately controlled.
With the anterior approach to hip replacement, patients typically are allowed to bend their hip freely immediately after surgery and walk with minimal assistance. Patients undergoing the posterior incisions are often required to follow strict precautions that limit the hip motion for the first two months and limit hip flexion to more than 60 degrees. These patients have also been discharged on a walker and face obstacle when trying to sit in a chair or on the toilet or just getting in a car.
