Anterior Hip Replacement Surgery

Hip replacement surgery removes the damaged joint lining and replaces the joint surfaces with an artificial implant that functions similar to a normal hip. A minimally invasive alternative to a traditional hip replacement surgery is anterior hip replacement surgery. This hip replacement technique achieves the same goal with less disruption to the surrounding muscles and soft tissues.

During an anterior hip replacement surgery, your hip doctor will access your hip between the two major muscles of the hip, rather than disrupting them or detaching them from your hip or femur. This allows for quicker rehabilitation, as the muscle tissue requires less time to heal.

Traditionally, hip arthroplasty, commonly known as hip replacement, has been performed by accessing the joint through the rear of the leg. Recent advances in technique, however, have made an anterior approach, during which the surgeon accesses the hip joint through the front of the leg, a more desirable option for most patients.

An anterior approach offers a number of advantages. Whereas during traditional hip replacement surgery, muscles had to be cut and subsequently reattached, using the anterior approach, these muscles need only be moved aside. Moreover, an anterior hip replacement provides the surgeon with the opportunity to clearly visualize the entire hip socket and to implant a variety of necessary devices.

The minimally invasive anterior approach also lowers the risk of dislocation common in other hip replacement procedures. By maintaining the integrity of the muscles and the hip capsule, this procedure also provides the stability to keep leg lengths equal and so avoids the need for leg lengthening.

Since less muscle damage takes place, anterior hip replacement often enables the patient to be hospitalized for a shorter period of time and to recover more quickly. In many cases, patients are walking without assistive devices 2 to 3 weeks after the operation. Low impact forms of exercise are recommended immediately after anterior hip replacement, and high-impact activities are typically only prohibited for 3 months.

The anterior hip arthroplasty is not equally well-suited to all patients. Patients who are not suitable candidates for anterior hip replacement include:

  • Those with previously implanted devices
  • Extremely muscular individuals
  • Obese patients

Whether an anterior approach to hip replacement is a viable option is determined after careful evaluation of the individual patient.
