This is a different operation to the total hip replacement. There is more bone preserved on the femur although often there is more taken from the acetabulum in the pelvis, to fit a larger cup.
It has some advantages over hip replacement for active, young, male patients, especially strong athletic patients and surfers. It is no longer available for women as an option which Dr Negus will be happy to discuss further on consultation.
There is some controversy surrounding resurfacing hip surgery due to a class action against a particular implant that failed early in many patients. There is a perception that all metal-on-metal prostheses and all resurfacings are the same and all bad. This is not supported by the data.
The decision to go ahead with a resurfacing usually requires more than one consultation and some special tests beforehand.
