Hip resurfacing is a bone-saving alternative to total hip replacement. This conservative surgical procedure aims to restore hip mobility and function by relining the hip joint; most of the healthy hip bone is preserved. The end of the thigh bone that fits into the hip socket is trimmed to remove only the arthritic or damaged portion, leaving the healthy part of the bone untouched. The surface is then covered with a thin, smooth metal dome.
Hip resurfacing can be performed safely in an outpatient setting, and patients can expect a quick recovery after surgery.

Advantages of hip resurfacing
The advantages of hip resurfacing over total hip replacement include:
- Minimal bone loss
- Shorter recovery time
- A smaller implant
- Easier revision: Components used in both procedures usually wear out, loosen or fail after a period of 10 to 20 years, requiring revision surgery. As hip resurfacing involves less removal of bone, the revision surgery should be easier to perform.
- Decreased risk of hip dislocation
- More natural walking pattern
- Greater range of hip motion
