Resurfacing procedures may be indicated in young male patients (Idealy less than 55 years) who have osteoarthritis and wishes to engage in high impact sports. It is a bone preserving alternative to Total Hip Replacement (THR)
The main advantage is that it is bone sparing in that it does not violate the femoral canal. This allows a Total Hip Replacement to be performed at a later date, if required, using primary femoral components.
| Total Hip Replacement | Hip Resurfacing |
| Suitable for women and men of all ages | Suitable for younger male patients |
| Femoral canal violation | Femoral canal left intact. |
| Metal on polyethylene, ceramic on plastic or ceramic on ceramic articulation | Metal on metal articulation |
| Does not tolerate high impact activities | Can withstand high impact activities like running. |
| Risk of dislocation. | Less risk of dislocation. |
| Risk of Leg length discrepancy (<2%). | Minimal or no leg discrepancy. |
| Risk of plastic wear | Risk of local and systemic reaction to metal. |
| Risk of Thigh pain (<5%) | No thigh pain |
| Requires some restriction of activities | Able to be more active |
