Anatomy of the hip

The hip is a ball-and-socket joint. Its socket—formed by the acetabulum—is part of the large pelvis bone. The ball (or femoral head) is the upper end of the femur (thighbone).

The bone surfaces of the ball and socket are covered with articular cartilage, a smooth tissue that cushions the ends of the bones and enables them to move easily. A thin tissue called a synovial membrane surrounds the hip joint.

In a healthy hip, this membrane makes a small amount of fluid that lubricates the cartilage and eliminates almost all friction during hip movement. The hip joint also contains bands of tissue called ligaments that connect the ball to the socket and provide stability to the joint.

Reasons patients get anterior hip replacements

If your hip has been damaged by arthritis, a fracture, or other conditions, everyday activities such as walking or getting in and out of a chair may be painful and difficult. Your hip may be stiff, and it may be hard to put on your shoes and socks. You may even feel uncomfortable while resting.

According to the Agency for Healthcare Research and Quality, more than 450,000 total hip replacements are performed yearly in the United States. This safe and effective procedure can relieve pain, increase motion, and help people return to enjoying regular activities.

Patients typically talk to a surgeon about hip replacement with the anterior approach when medications, changes in everyday activities, walking support use, and other nonsurgical treatments are ineffective.

Who benefits from an anterior hip replacement procedure?

Total hip arthroplasty (THA) is an option for any patient needing a hip replacement, not just patients with an average body mass index (BMI) or who are active. This muscle-sparing approach can lead to a faster recovery with less pain and fewer movement restrictions, which makes it a good choice for those wanting to return quickly to daily activities.

Who should avoid anterior approach hip replacement surgery?

There aren’t any true contraindications or reasons to avoid total hip replacements with an anterior approach.

4 advantages of anterior hip replacement

Anterior hip replacement surgery offers several advantages, including:

  • Less damage to major muscles
  • Less post-operative pain
  • Faster recovery
  • Fewer post-surgical precautions

Less damage to major muscles

When performing an anterior total hip replacement, a surgeon doesn’t cut or detach any of the muscles to the hip but instead works between the natural spaces between them.

Less post-operative pain

By not cutting major muscles, there is less pain after surgery and less need for pain medication.

Faster recovery

Research shows that people with anterior hip replacements stop using walkers, canes, and other assistive devices sooner than traditional hip surgery patients.

Fewer post-surgical precautions

While the anterior approach to hip arthroplasty is an excellent choice for first-time hip replacements, revision (or re-do) surgeries may be limited by this technique. Additionally, patients with certain body types may be at a higher risk for wound complications with anterior total arthroplasty. Patients who have undergone an anterior hip replacement should also avoid sleeping in certain positions or with pillows between their legs.

That said, anterior approach patients can do some activities (such as crossing their legs or bending over immediately) which aren’t recommended for those who underwent hip arthroplasty using other approaches.

What happens during anterior hip replacement

Most total hip replacements are done under spinal anesthesia. Patients are given shots in their backs that make their legs numb. In addition, they’re given medicine to help them disassociate while surgery is performed. With this method, patients breathe independently while their hips are being replaced. By avoiding the use of breathing tubes or anesthesia gases, they come out of surgery feeling much better and more alert.

Also, before the anterior hip replacement procedure begins, the skin around the surgical site is cleaned, and all hair is removed. Your surgeon will then cut in front of your hip joint and separate your muscles to see your hip joint.

Next, your surgeon removes the upper part of your femur and the damaged cartilage and bone from your pelvis. Then, the surgeon replaces the hip joint with an implant that consists of a metal socket and a new ball (which is anchored into the thigh bone).

Another advantage of the anterior approach is that surgeons can use X-rays during the procedure to confirm a patient’s implants are appropriately positioned and their legs are the same length.

Finally, the surgeon or an assistant closes the incision.

What’s new in the anterior hip replacement approach

Other innovative options besides the direct anterior approach are available to tailor an arthroplasty procedure to your needs.

Some of the hip replacement advances include the following, which aim to provide better surgical precision, faster recovery times, and better outcomes:

  • Mako robot-assisted hip replacement: Using a patient-specific 3D model as a guide, surgeons can place artificial joints more precisely during hip arthroplasty. The Mako technology also streamlines removing the diseased bone (and preserving healthy bone).
  • Computer-assisted (image-guided) hip replacement: This technology for hip arthroplasty incorporates digital imaging and navigation tools, which help surgeons enhance precision and improve overall implant placement accuracy.
  • Cementless (press-fit) hip replacement: This method, used during hip arthroplasty, involves securing implants without bone cement, allowing natural bone growth to hold them in place.
  • Outpatient (same-day) hip replacement: Patients who choose this option can avoid a hospital stay and return home on the same day as their surgery.
