What it is
Hip replacement replaces the worn femoral head and socket surfaces with implants. Total replacement replaces both sides; partial replaces the ball only.
The goal is to reduce pain and restore function when non-surgical care no longer meets goals.
What happens when it occurs
Damaged joint surfaces are removed and replaced. Early movement and strength restore function while tissues heal.
Common causes and risk factors
- Hip osteoarthritis, avascular necrosis, or fracture
- Ageing, previous hip deformity or injury
- Higher body weight and demanding work increase symptom burden
Who is most affected
Adults whose pain and limitation persist despite best non-surgical care.
Typical symptoms pre-op
- Groin or buttock pain, stiffness, and difficulty with shoes, stairs, and walking distance
- Sleep disturbance and reduced activity levels
When to seek care
Seek surgical review when pain limits life despite structured rehabilitation and self-management.
How we diagnose
History, examination, and X-rays. Pre-operative screening assesses medical readiness and goals.
Management
- Prehab to build strength and plan the home environment
- In-hospital early mobilisation and walking aids
- Clinic-based strength, balance, and gait training
- Ongoing activity plan including walking and cycling
Rehabilitation milestones
Phase 1 days 0 to 7: transfers, walking with aids, basic strength.
Phase 2 weeks 1 to 6: progress strength and gait, stairs.
Phase 3 weeks 6 to 12: balance, endurance, community walking.
Phase 4 months 3 to 6: return to chosen low-impact activities.
Readiness to progress
- Pain controlled and wound healing satisfactory
- Gait with minimal aid and safe stair negotiation
- Strength and balance targets met
Prevention / long-term care
- Maintain strength and healthy weight
- Avoid high-impact overloads unless cleared
- Follow dental and infection precautions as advised
Australia snapshot
- Hip replacement is a common elective operation with high satisfaction rates
- Performed widely in public and private hospitals
- Rehabilitation support and community exercise programmes are widely available
Latest insights
Prehab improves early outcomes. Early, safe walking accelerates recovery.
Strength and balance predict independence more than implant brand or approach.
