Hip pain affects millions worldwide. When walking, bending, or even resting becomes painful, surgery may be the solution. But should you choose hip resurfacing or hip replacement?
Both surgeries are effective, but they suit different patients. This article explains the differences, benefits, and risks, helping you understand which option may be right for you.
Understanding Hip Joint Problems
The hip is a ball-and-socket joint, designed for smooth movement. When cartilage wears down or the joint is injured, pain and stiffness follow.
Common Causes of Hip Pain
- Osteoarthritis – gradual cartilage wear and tear.
- Rheumatoid arthritis is an inflammatory condition.
- Fractures – often from falls or injuries.
- Avascular necrosis – reduced blood supply causing bone damage.
According to the World Health Organization, osteoarthritis now affects over 528 million people worldwide, with hip arthritis being a leading cause of disability.
What Is Hip Replacement?
Total hip replacement (THR) is one of the most common orthopaedic surgeries.
How It Works
- The damaged ball (femoral head) is removed.
- A prosthetic stem with a new ball is placed into the thigh bone.
- The socket is replaced with a cup liner for smooth movement.
Why It Works
Hip replacement provides long-lasting pain relief and restores mobility for patients with severe arthritis or bone damage.
What Is Hip Resurfacing?
Hip resurfacing is an alternative to replacement, but instead of removing the ball entirely, it reshapes and caps it.
How It Works
- The femoral head is trimmed and covered with a smooth metal cap.
- The socket is fitted with a matching metal cup.
Why It Works
This preserves more of the natural bone, which can be beneficial for younger, more active patients.
Who Is a Good Candidate?
Best Suited for Hip Replacement
- Older patients with advanced arthritis.
- People with fragile bones or osteoporosis.
- Patients need a reliable long-term solution.
Best Suited for Hip Resurfacing
- Younger patients (usually under 60).
- Men with strong bone density.
- People who want to maintain higher levels of activity.
Resurfacing is less suitable for women due to higher risks of bone fractures.
Comparing the Two Options
Bone Preservation
- Replacement removes more bone.
- Resurfacing saves more bone, especially in the femur.
Longevity
- Replacements last around 15–20 years.
- Resurfacing can also last long, but it depends heavily on bone strength.
Activity Level
- Replacement patients may need to avoid high-impact sports.
- Resurfacing patients often return to more active lifestyles.
The Numbers That Matter
- In Australia, over 50,000 hip replacements are performed each year.
- Research shows 95% of replacements last at least 15 years.
- Resurfacing accounts for less than 10% of hip surgeries worldwide, but satisfaction is high among suitable patients.
Risks of Each Procedure
Hip Replacement Risks
- Infection
- Blood clots
- Implant loosening
- Dislocation of the new joint
Hip Resurfacing Risks
- Femoral neck fractures
- Metal ion release into the bloodstream
- Limited suitability for those with weaker bones
Recovery Expectations
Hip Replacement Recovery
- Walking begins within 1–2 days.
- Hospital stay lasts 2–5 days.
- Most patients return to daily activities in 6–12 weeks.
- Full recovery often takes 6–12 months.
Hip Resurfacing Recovery
- Similar short-term recovery timeline.
- Active patients often regain movement and confidence sooner.
Long-Term Outcomes
Both surgeries deliver significant improvements.
- Hip replacement patients experience reliable, long-term pain relief.
- Hip resurfacing patients often maintain a greater range of motion and return to more active lifestyles.
A Lancet study confirmed that over 90% of patients report major improvements in pain and mobility after hip replacement. Resurfacing, when performed on the right candidates, shows similar satisfaction rates.
Choosing the Right Option
Your decision depends on:
- Age – Younger patients may benefit more from resurfacing.
- Bone quality – Stronger bones allow for better resurfacing outcomes.
- Lifestyle – Active individuals often prefer resurfacing.
- Gender – Men are more likely to be candidates than women.
The Role of Expertise
The experience of your surgeon makes a significant difference in outcomes. Proper evaluation and precise surgical technique lead to better results and fewer complications.

Conclusion
Hip resurfacing and hip replacement both offer life-changing relief from chronic hip pain.
- Replacement is the gold standard, particularly for older patients or those with weaker bones.
- Resurfacing is best for younger, active patients with strong bone quality.
The right choice depends on your health, activity level, and long-term goals. With expert care, both procedures can restore movement, reduce pain, and improve your quality of life.
