Hip resurfacing arthroplasty replaces the arthritic surface of the hip. Much less bone is removed compared with the traditional total hip replacement.
Because the hip resurfacing removes less bone, it may be a better option for younger patients who may need a second hip replacement surgery later. A revision operation may be needed as they grow older and wear out the original artificial hip replacement.
As far as improvements in the hip implants, there may not be a big difference in just the past year. But much has changed from when the procedure was first introduced.
Changes in the implant design and better surgical tools have helped reduce the 30 per cent failure rate that was reported early on. There are also fewer dislocations and the joint is preserved.
Patients are selected more carefully now than at first. Research has shown that obese adults over the age of 65 are not good candidates for this surgery. Anyone who has osteopenia is also at increased risk for problems. Osteopenia is a decrease in the mineral content of the bone. These patients are more likely to need a total hip replacement.
If you have had your hip resurfaced in the past year, most likely you received the most up-to-date implant and surgical methods. In the future, researchers will continue to find ways to expand who can benefit from this operation.
