Hip Resurfacing Arthroplasty
Hip resurfacing arthroplasty is surgery that replaces the damaged outer surfaces of the femoral head found at the top of theand, if needed, the cup-shaped socket where the meets the pelvis in the hip joint.
People younger than about age 55 who have hip osteoarthritis have been difficult to help with standard hip replacements. They have many years of activity ahead of them and put a lot ofon their replaced hip joint. So their hip replacements often need to be redone a few years after the original surgery. These later surgeries are usually less successful than the original hip replacements.
Hip resurfacing removes lessthan a hip replacement and maintains a better ball and socket joint. The chances of hip dislocation are less than with hip replacement. And people usually find the eventually feels normal after the surgery. Also, if the resurfacing parts eventually need to be replaced, there is enough remaining to do a standard hip replacement.
Hip resurfacing seems to work best for people who have a larger "ball" (femoral head) at the top of their thigh bone. Women, and men with smaller femoral heads, may be more likely to need further surgery than if they had a total hip replacement.footnote 1 And it is not clear that people with severe who have hip resurfacing are able to be more active than people who have hip replacement. footnote 2 Long-term studies of hip resurfacing have not been done. If you are considering hip surgery for severe , talk to your doctor about the risks and benefits of each type of surgery.
