What is Hip Resurfacing?

what-is-hip-resurfacing

Hip Surface Replacement or Hip Resurfacing is a type of hip replacement procedure in which the femoral (thighbone) head is trimmed and capped with a metal ball that moves in a metal socket, as opposed to being removed completely, like during a total hip replacement. Your surgeon may opt to use digital templating software before your surgery to help pre-operatively plan your operation and calculate which ball and socket is best for you.

This type of surgical treatment may be recommended if you are in advanced stages of debilitating arthritis and have explored all of your non-surgical options. Similar to total hip replacement, hip resurfacing is not recommended for all patients. Your doctor may tell you that hip resurfacing is best for younger (under 60), larger-framed patients with strong, healthy bones. Your doctor will evaluate if you are a candidate for hip resurfacing based on your specific diagnosis, medical history and risk factors.

The pros and cons of hip resurfacing is a topic of research and controversy among orthopedic surgeons. We’d like to share an overview with you here; however, we encourage you to do more research if considering hip resurfacing as your best surgical option.

Pros:

  • If necessary, failed implants may be easier to replace in a revision surgery as it is less invasive on the side of the femur.
  • Smooth metal covering creates a closer-to-natural shape of the femoral head, potentially decreasing risk for dislocation and achieving subtle advantages in natural walking pattern.

Cons:

  • A small fraction of patients may experience a break in the thighbone at the femoral neck. If this occurs, the patient usually requires a total hip replacement.
  • Over time, some patients may acquire sensitivity or an allergy to the metal particles produced by the metal ball and socket. If this occurs, the patient may experience pain and swelling.
  • A larger incision is typically necessary as hip resurfacing is more difficult than total hip replacements, which could result in a larger scar.1
