Both hip resurfacing and replacement surgeries are practical options for reducing hip joint discomfort. However, the terms refer to different procedures, meaning the terms should not be used interchangeably. In this article, we’ll dissect the differences between hip resurfacing and replacement.

Examining The Difference Between Hip Resurfacing and Hip Replacement
Total hip replacement involves removing both the femoral head (top of the thighbone) and the damaged acetabulum (hip socket). These parts are then replaced with components made from metal, plastic, or ceramic.
Hip resurfacing, on the other hand, preserves more of the natural bone. Instead of removing the femoral head, it is reshaped and capped with a smooth metal or ceramic surface. This procedure is often recommended for younger, more active individuals as it allows for a greater range of motion and retains more of the original bone structure.
Key Differences Between Hip Resurfacing and Replacement
- Bone preservation: Hip resurfacing results in less bone removal from the femur, which can be beneficial if revision surgery is needed in the future.
- Lower dislocation risk: The larger size of the resurfaced femoral head more closely mimics the natural joint, which may reduce the risk of dislocation.
- More natural movement: Some studies suggest walking patterns after hip resurfacing are closer to natural gait compared to total hip replacement, though the differences are often minimal.
Considerations for Hip Resurfacing
- Revision surgery: Implants from both procedures can wear out over time. Hip resurfacing typically lasts 15 to 20 years. If a revision is needed, resurfacing may be easier to revise because more of the femur is preserved.
- Fracture risk: A small percentage of patients may experience a fracture in the femoral neck after resurfacing. If this occurs, it can often be converted to a total hip replacement.
- Metal ion exposure: Because hip resurfacing uses metal-on-metal components, friction can produce tiny metal ions. In some people, this can lead to pain, swelling, or an adverse tissue reaction that may require revision surgery.
- Not suitable for everyone: Hip resurfacing is not recommended for people with metal allergies, kidney problems, small or weak bones, abnormal bone structure, or those with low activity levels. In these cases, a total hip replacement may be more appropriate.
Recovery and Outcomes
Both hip replacement and hip resurfacing offer similar recovery times and can often be performed as outpatient procedures. Recovery typically includes pain relief, improved mobility, and the ability to return to everyday activities, such as walking, climbing stairs, or putting on shoes, without restriction.
Choosing the Right Procedure
Your orthopedic specialist will evaluate your condition, activity level, bone structure, and overall health to determine which surgery is best for you.
While both procedures can deliver excellent outcomes, hip surgery is entirely elective. If you’re not ready now, it’s usually possible to opt for surgery at a later stage.
The Role of a Specialist During Hip Resurfacing or Replacement
A specialist, such as an orthopaedic specialist or surgeon, should be available to answer any questions you may have throughout the hip surgery process.
They should initially provide you with all the information you need to make an informed decision about your treatment. They should then monitor your progress while providing guidance and support.
