Patients with advanced arthritis of the hip may be candidates for either traditional total hip replacement (Arthroplasty) or hip resurfacing (Hip Resurfacing Arthroplasty). Each of these procedures is a type of hip replacement, but there are important differences. Your orthopaedic surgeon will talk with you about the different procedures and which operation would be best for you.
The hip is a ball-and-socket joint. In a healthy hip, the bones are covered with smooth cartilage that enables the femoral head and acetabulum to glide painlessly against each other.
In a traditional total hip replacement, the head of the thighbone (femoral head) and the damaged socket (acetabulum) are both removed and replaced with metal, plastic, or ceramic components.
In hip resurfacing, the femoral head is not removed, but is instead trimmed and capped with a smooth metal covering. The damaged bone and cartilage within the socket is removed and replaced with a metal shell, just as in a traditional total hip replacement.
