This document compares traditional total hip replacement surgery to hip resurfacing surgery. In total hip replacement, both the femoral head and acetabulum are replaced with prosthetics, while hip resurfacing only replaces the acetabulum and caps the femoral head with metal. Younger, larger patients with healthy bone are generally best suited for hip resurfacing, which involves reshaping and capping the femoral head rather than full replacement. The document goes on to describe the procedures and recovery process for hip resurfacing surgery.
