Total hip replacement is among the most reliable operations in orthopaedic surgery, and the registry evidence on how long implants last is correspondingly good. National joint registries record every replacement submitted and note when one requires revision, which gives a far more honest picture than any single surgeon’s series could.
A recent review of national registry data estimated 93.6% survivorship for contemporary total hip replacements at 20 years. This is a population estimate, not a prediction for an individual, and does not show that robotic surgery extends implant life. Source: systematic review and registry analysis.
As with the knee, these are population figures rather than a prediction for any individual. Age at operation is the single largest influence: a hip replaced in a patient in their fifties must survive far more walking cycles than one replaced at eighty. Body weight, activity pattern, bone quality and the accuracy of component positioning all contribute.
Component position is one factor surgeons consider in hip replacement planning. Robotic assistance can support planning and positioning, but current comparative evidence has not established that it reduces long-term revision or extends implant survival compared with conventional surgery.

What influences how long a hip replacement lasts
- ✓Age and activity demands at the time of surgery
- ✓Accuracy of acetabular cup position and version
- ✓Bearing surface and implant design
- ✓Body weight and load through the joint
- ✓Bone quality and the security of fixation
- ✓Avoidance of infection, early and late
Practice across two health systems
Dr. Chetan M. Dojode has operated in both the United Kingdom and India. His UK joint replacement practice is recorded on the National Joint Registry (NJR) — the world’s largest independent registry of joint replacement outcomes, which tracks implant survival and revision rates for every procedure submitted. The principles of systematic outcome tracking and evidence-based practice that underpin his UK joint replacement practice continue to inform his joint replacement practice in Bengaluru.
Frequently Asked Questions
How long does a hip replacement last on average?
A recent review of national registry data estimated 93.6% survivorship for contemporary total hip replacements at 20 years. This is a population estimate, not a prediction for an individual, and does not show that robotic surgery extends implant life. Source: systematic review and registry analysis.
Am I too young for a hip replacement?
Age alone rarely decides it. The concern in younger patients is that the implant must last longer under greater demand, making later revision more likely. Where the hip is destroyed by arthritis or avascular necrosis and pain is disabling, replacement may still be entirely appropriate — with the expectation that revision could be needed in later life.
What activities should I avoid after hip replacement?
Low-impact activity such as walking, cycling, swimming and golf is encouraged. Running, jumping and contact sport place repetitive high load through the bearing and are generally discouraged. Deep flexion combined with rotation carries a dislocation risk in the early months; specific precautions depend on the surgical approach used.
Does robotic hip replacement last longer?
Robotic assistance can support planning and component positioning. Current comparative evidence has not established that it reduces long-term revision or extends implant survival compared with conventional surgery. Implant longevity depends on multiple patient, implant and surgical factors.
What happens if a hip replacement wears out?
It can be revised: the worn components are removed and replaced. Revision hip surgery is more complex than the original operation, particularly where bone stock has been lost, and outcomes are generally less predictable. This is why the first replacement is planned with the long term in view.
