Dr. Hansen Compares Hip Resurfacing and Total Hip Replacement

Hip resurfacing procedures are rarer than they used to be; Dr. Hansen explains why.

Today, medical advances offer safe and effective hip replacement surgeries for people with hip arthritis. Hip resurfacing and total hip replacement procedures are two surgeries used to correct hip joint dysfunction. Arthritis specialist and hip surgeon Dr. Dane Hansen discusses the differences between these two replacement procedures and explains why surgeons increasingly recommend total hip replacement over resurfacing procedures.

The difference between hip resurfacing and total hip replacement

“Both hip surgeries are full joint replacement procedures,” says Dr. Hansen. “Both surgeries treat the ball and the socket in the hip joint. But there are differences in the implant materials used and in the degree to which the joint anatomy is affected.”

Dr. Hansen notes that the incisions for both procedures are quite similar. “Because we preserve more bone in hip resurfacing, it requires a slightly larger incision to provide the mobility to manipulate the bone,” he says. “Otherwise, the recovery protocols are essentially the same. With both procedures, patients can bear weight and walk right away after surgery.”

How advancing technology has influenced procedure preferences

“Historically, the main advantages of resurfacing were the metal-to-metal contact and maintaining the patient’s own femoral neck,” notes Dr. Hansen. “Patients could resume high-impact activities like running or basketball without restriction. By contrast, patients had a lot of activity restrictions following a total hip replacement. Total hip patients were instructed to avoid rigorous activity for fear that the plastic component of the implant would wear out. As a result, hip resurfacing was preferred for young active patients.”

However, as plastics technology advanced, so did the longevity of total hip implants. “The plastics durability in total hip implants has drastically improved over the last 15 to 20 years,” explains Dr. Hansen. “Plastic components used through the ’90s had a 15- to 20-year life expectancy. But new plastics introduced in the early 2000s show  minimal signs of wear. Until long-term data is available, we don’t know the true longevity of these new hips. I tell my patients that we expect them to last for 30 years, and maybe more. These new plastics have reduced age-related concerns about traditional hip replacements and reduced the need for hip resurfacing procedures.

The amount of rigorous exercise recommended with today’s total hip replacements is a controversial subject among surgeons. “Some surgeons are adamant that total hip patients continue to avoid rigorous and high-impact activities,” says Dr. Hansen. “But there’s no data supporting this continued caution. We do know that the new implants hold up well under exercises like weightlifting and cycling—that are rigorous without being high-impact. I would not be surprised if research eventually confirms that current total hip implants hold up just as well as the metal-on-metal resurfacing implants.”

Factors contributing to decreasing use of hip resurfacing procedures

“Resurfacing is still used to treat some patients, but it is a lot less common than it used to be,” says Dr. Hansen. “I am not aware of any surgeons at Summit performing this procedure, and there are only a few surgeons offering it in the Twin Cities. There are a number of reasons for the declining use of resurfacing to treat hip joint issues.”

The future of hip joint implants

“Technology is always advancing,” says Dr. Hansen. “New, more durable plastics make total hip replacement a good option for a broader range of patients. With current technology, patients 50 years old or older can feel confident that their first total hip replacement will be the only one they’ll need. Obviously, the younger you are, the more likely you are to wear out even a modern hip replacement. But if a young patient has a trauma-related hip injury or a condition like hip dysplasia, juvenile rheumatoid disease, or bone death related to avascular necrosis, a hip replacement is a reasonable option. Every patient’s circumstances have to be evaluated independently. Here at Summit, my colleagues and I are constantly following medical advances and clinical trials to make sure our patients have safe and effective treatments to support them in living their best lives.”
