Direct anterior approach causes less pain, recovery time for hip replacement
When your doctor suggests a total hip replacement, the treatment can seem overwhelming. The good news is that as technology has improved, minimally invasive surgical techniques have allowed patients to recover sooner.
One of those techniques is the direct anterior approach to total hip replacement. This procedure uses a special operating table to allow surgeons to access the hip from the front of the body. Doing so causes little or no muscle damage during the procedure and less in the center for patients with fewer restrictions because it is not necessary to cut the muscles to access the joint.
It is estimated that about 20-30% of total hip replacements in the United States today are performed using the direct anterior approach. Our subspecialized hip care team treats hundreds of patients each year with this technique.
The most common diagnoses requiring hip replacement include arthritis (related to aging and normal wear and tear) and trauma (an injury). Read on for some frequently asked questions and answers about this approach and whether it might be right for you.
What is the direct anterior approach?
It is an advanced technique that causes little or no muscle damage - the surgeon approaches the hip from the front of the body near the top of the leg. The location is between the muscles and does not need to be separated from the pelvis or femur, which has been the standard in conventional total hip replacement. The patient lies on his back on a special operating table designed for his procedure. The surgeon makes a small incision in the front of the hip, which causes less trauma to the body through less disruption of the muscles.
What are the benefits?
With traditional total hip replacement, patients must restrict hip movement and hip flexion beyond 90 degrees for six to eight weeks. The direct anterior approach allows patients to bend their hips more freely and bear full weight as soon as they feel comfortable doing so, so they can return to their daily activities sooner.
Additional benefits include a shorter or no hospital stay, a smaller incision, less pain and risk of dislocation, better implant position due to the use of images during surgery, and less chance of leg length discrepancy .
Is the direct anterior approach right for me?
Patients in good general health are often the best candidates for the direct anterior approach. Additional factors such as bone quality and a person's anatomy (even if the hip joint is severely deformed) could also affect whether they are a good candidate.
