Hip Resurfacing

This means the femoral head has some or very little bone removed and replaced with the metal component. This spares the femoral canal.

Resurfacing procedures may be indicated in the young patient (usually less than 55years) who has osteoarthritis and wishes to maintain an active lifestyle. It is a more conservative and less traumatic alternative to Total Hip Replacement (THR)

Hip Resurfacing procedures were designed to preserve bone so that should a patient require a revision in the future there was adequate bone left to revise the hip. This type of replacement is reserved for patients with good quality bone and therefore not recommended for patients with osteoporosis.

Advantages of Hip Resurfacing

The main advantage of a hip resurfacing compared to a total hip replacement is preservation of bone at the top of the thigh bone. Should the patient require further surgery for loosening of the artificial joint replacement, preserving this bone makes the revision surgery less complex, shortening the recovery time and improving the durability of the second operation. Preserving bone is therefore most important in younger patients with higher activity demands, who may potentially outlive an artificial joint replacement of any design.

Hip resurfacing patients can take longer to recover than conventional total hip surgery patients. The reason for this is that in order to preserve the femoral head for resurfacing, more muscle and ligaments need to be released internally to allow the socket to be prepared. Patients are advised to partial weight bear for 4 weeks post operatively to allow the bone to adapt to the new implant and not fracture. Conventional hip replacement patients are allowed to full weight bear immediately.
