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.

Frequently Asked Questions

Modern implants have strong long-term results. Lifespan depends on use, bone quality, and surgical factors.

Your team will advise based on approach. Early on, avoid extremes that stress the healing capsule.

When you can walk confidently without strong pain and react quickly; confirm with your surgeon and insurer.

Yes, usually between 6 and 12 weeks as strength and balance improve.

Sometimes. A joint card is available but not required.

Expect improvement over weeks. Contact your team if pain escalates or is accompanied by fever or wound change.
