About Anterior Approach "ASI" Hip Replacement

OPA’s hip-replacement team now offers the increasingly popular Anterior Supine Intermuscular (ASI) hip-replacement technique.

This is a minimally invasive technique that involves approaching the joint from the front of the hip instead of the side or rear. This allows the surgeon to access the hip by going between the surrounding muscles and tendons instead of having to cut or detach them.

The result for the patient is reduced trauma to the surrounding soft tissue, less postoperative pain and a faster recovery. Most patients will be up and walking shortly after the procedure — and are encouraged to put full weight on the hip immediately.

Recovering from an ASI replacement is easier than with other techniques. There are no leg-position restrictions and patients may use a standard toilet and sit with crossed legs. In some cases, physical therapy will be needed to work through any weakness or stiffness. Recovery times vary, but typically patients can expect to drive in 2 weeks, garden and perform other light activities in 3-4 weeks and golf, hike or bike in 4-6 weeks.

Hundreds of thousands of people undergo total hip replacement every year in the United States. The ASI technique was introduced to the U.S. in the 1980s. As specialized instrumentation and equipment evolved, so did the popularity of this anterior method. Today, many patients demand it.

OPA ASI hip surgeons are among the leading hip-replacement surgeons in the western U.S. and have completed special training to perform the procedure in a way that makes it both more efficient and less costly to the patient.
