Understanding Hip Replacement
Total hip replacement (THR) removes the damaged ball and socket of the hip joint and replaces it with prosthetic components. It is one of the most transformative surgeries, eliminating severe hip pain and restoring walking ability.
Conditions That Lead to Hip Replacement
- Osteoarthritis (most common)
- Rheumatoid arthritis
- Avascular necrosis (bone death due to poor blood supply)
- Hip fracture in elderly patients
- Childhood hip dysplasia causing adult arthritis
The Surgery
THR takes 1.5–2 hours. The surgeon removes the worn femoral head and acetabular cartilage, then fits metal, ceramic, or polyethylene implants. Modern techniques (anterior approach) allow faster recovery with less muscle damage.
Recovery Milestones
- Day 1–2: Standing and walking with a walker
- Week 2–4: Walking independently indoors
- Month 1–3: Return to most daily activities
- Month 3–6: Driving, light sport, stairs without aid
Precautions After Hip Replacement
- Avoid crossing legs for 6 weeks
- Use raised toilet seats and grab bars
- Sleep with a pillow between knees initially
- No low sofas or bending past 90 degrees (posterior approach)
FAQ
How long does a hip replacement last? 90% of hip replacements last 15–20 years. Highly cross-linked polyethylene and ceramic bearings in modern implants can last 25+ years.
Is hip replacement done under general anaesthesia? Most surgeons prefer spinal (regional) anaesthesia — you are awake but numb from the waist down, with less risk and faster recovery than general anaesthesia.
