What is the Direct Anterior Approach?
The direct anterior approach is a minimally invasive technique in which the hip joint is accessed without cutting any muscles or tendons. The procedure is done under image guidance, facilitating safe and accurate component placement. The direct anterior approach is also associated with decreased soft tissue damage, reduced pain, lower dislocation risk and a faster initial recovery.
What Should I Expect During a Direct Anterior Total Hip Replacement?
Surgery is usually done under spinal anesthesia and takes about an hour to perform. Unlike other approaches to hip replacement, during a direct anterior approach patients lie on their back rather than on their side during surgery. The hip is accessed with careful attention to protection of soft tissues. The damaged bone is then removed from the hip. The socket is resurfaced and replaced, followed by the femoral component and ball, all using image guidance technology. The hip is thoroughly tested for stability and range of motion prior to final implant placement. Once all components are in place, the incision is typically closed with a dissolvable suture beneath the skin.
What is the Postoperative Course After a Direct Anterior Total Hip Replacement?
Immediately after the procedure patients can typically put their full weight on their surgical leg. The majority of patients are discharged home on the day of surgery. Outpatient physical therapy is usually not required, as the best therapy consists of walking. Dr. Phillips asks you to avoid “warrior 2 pose” (where your operative leg is behind you with your toes pointed away from you) for 6 weeks. By 12 weeks, most patients are well recovered and returning to athletic activities. However, small gains can be made out to the 1 year mark when full recovery has occurred.
Is the Direct Anterior Approach Right For Me?
Dr. Phillips tailors her treatment approach to each unique patient and their mobility goals. Every approach to hip surgery carries a unique set of risks and benefits. Dr. Phillips will have a detailed discussion about the various strategies for executing your hip replacement, including whether a direct anterior approach is optimal for you.
