Resurrection of hip resurfacing: what is the evidence?

Abstract

Total hip resurfacing has long been conceptually attractive to both surgeons and patients. However, historically it has been plagued by limited durability and marked acetabular bone loss. The recent development of wear-resistant bearings, such as metal-on-metal, has led to renewed interest in hip resurfacing in the orthopedic community. Several resurfacing implants have been designed and positive results, particularly in young patients, have been reported. Although comparative studies of hip resurfacing and standard total hip replacement are still lacking, we believe that there is now evidence to demonstrate that this surgical concept deserves consideration, particularly when treating young patients with hip diseases.
