Minimally Invasive Anterior Hip Replacement: Innovative Procedure Reduces Pain, Speeds Recovery

Minimally Invasive Anterior Hip Replacement: Innovative Procedure Reduces Pain, Speeds Recovery

The demographics – and the numbers – for hip replacement surgery are changing.  According to the American Academy of Orthopaedic Surgeons, between 200,000 and 300,000 total hip replacements are performed in the United States each year, the majority of them on people over the age of 60. But the number of total hip replacements performed on younger people is increasing. The development of longer lasting prostheses and advances in surgical techniques are driving younger people to avoid postponing the procedure. One of the most important surgical advances is anterior hip replacement, a minimally invasive procedure that reduces pain and speeds rehabilitation. Realizing that hip replacement can be less disruptive to their lives than in the past, many people suffering from arthritis and degenerative disorders are choosing not to endure years of discomfort and restricted activity and are opting for surgery at younger ages and in increasing numbers.

Conventional v. anterior hip replacement

In conventional hip replacement procedures, the surgeon accesses the hip joint from the lateral (side) or posterior (rear) position and must detach muscles from the femur or pelvis to expose the hip. In anterior hip replacement, the hip is approached from the front and the most important muscles for hip function are undisturbed. By accessing the hip joint from the front the surgeon can work through a natural plane in between the muscles. Leaving the muscles intact reduces trauma to the hip area and dramatically improves recovery and rehabilitation for the patient.

Faster recovery, shorter hospital stays

Anterior hip replacement surgery typically reduces the hospital stay to 2-3 days but even more dramatic improvements in recovery time are seen after the patient leaves the hospital. The faster recovery enables patients to get back to work quicker which is certainly a key advantage of this approach.

Conventional hip replacement  imposes strict post-surgical precautions such as limiting hip motion for as long as 6-8 weeks and avoiding flexing the hip more than 60 to 90 degrees. These constraints make daily activities like sitting, bending and walking up stairs difficult. After anterior hip replacement, patients can bend the hip right after surgery and are instructed to use the hip normally. They can bear their full weight as soon as they can do so comfortably, which enables quicker return to normal function. It’s gratifying to see many patients at their first office visit two weeks after discharge walking with only a cane or even unassisted.

Most patients who are candidates for traditional hip replacement are also candidates for the anterior procedure. Exceptions include those who are undergoing revision of a previous surgery and those with certain deformities of the hip.

The pain caused by wear and tear of the hip bones can be debilitating. With the development of prostheses that can be expected to last many years and with new surgical techniques like anterior hip replacement that are less disruptive to patients’ lives, we’re seeing more people opt for replacement surgery sooner rather than later. The anterior procedure offers people of all ages a way to resume their normal activities quickly and enjoy an improved quality of life for many years to come.
