When Is Hip Replacement Needed?
Hip replacement is considered for advanced hip arthritis (osteoarthritis, rheumatoid arthritis, or avascular necrosis) when pain limits walking, sleep and daily life despite conservative treatment. It is also used for certain hip fractures in older adults. The damaged hip joint is replaced with an artificial ball-and-socket implant.
Surgical Approaches
- Total hip replacement (THR): Both the ball (femoral head) and socket are replaced — the standard for advanced arthritis.
- Surgical approach: Posterior, lateral or anterior approaches are used; the anterior approach may offer faster early recovery in suitable patients.
- Hemiarthroplasty: Replacing only the ball — used for certain hip fractures.
Implant materials and bearing surfaces are chosen for durability based on age and activity.
Recovery Timeline
- Hospital stay: Typically 2–4 days; walking with aids starts the day after surgery.
- Weeks 2–6: Increasing independence with physiotherapy; following hip precautions to protect the new joint.
- Months 3–6: Return to most activities; many patients are very satisfied with pain relief.
Choosing a Surgeon
Hip replacement is performed by orthopaedic surgeons in licensed hospitals. Discuss the surgical approach, implant choice and expected recovery. As with knee replacement, physiotherapy and following post-operative precautions are key to a smooth recovery.

Browse orthopaedic surgeons →At public hospitals, subsidised hip replacement can cost roughly S$9,000–S$17,000+ after subsidies and Medisave (varies with means-testing). Private hip replacement typically ranges from S$22,000 to S$38,000+. It's medically necessary, Medisave-claimable and usually Shield-covered.
Modern hip implants commonly last 15–25 years or more. Longevity depends on activity, weight and implant type. Many people never need a revision; younger, more active patients may eventually require one.
Most people walk with aids the day after surgery, go home within a few days, and progress over 6 weeks with physiotherapy. Return to most daily activities takes around 3 months, with high satisfaction from pain relief.
Yes. Hip replacement is medically necessary and Medisave-claimable up to surgical limits, with subsidies in the public sector and Integrated Shield Plan coverage privately. Confirm with the hospital.
