Anterior Approach Hip Replacement.

The technique

The incision sits on the front of the thigh. Rather than cutting through the gluteal muscles (as posterior approaches do), the surgeon works in the natural interval between the muscles — no tendons are divided. The hip is then dislocated forwards, the joint surfaces prepared, and the implant inserted.

Because the soft-tissue envelope around the hip is preserved, the joint is stable in nearly all post-operative positions.

Benefits — with data

• Shorter hospital stay — typically 1–2 nights vs 2–3 for a traditional approach
• Faster balance recovery — many patients walking without an aid within two weeks
• Lowest dislocation rate — 0.2–0.5% with anterior approach vs around 1% with posterior approach
• No hip precautions post-operatively — you can bend, twist, and sit normally

Specific risks

The anterior approach has its own risk profile to discuss:

• Lateral femoral cutaneous nerve injury — temporary or persistent numbness on the outer thigh; usually settles
• Slightly elevated femoral fracture risk — under 0.5%, related to the angle of femoral preparation

Suitability

The anterior approach is not suitable for every patient. Body habitus, prior surgery, hip anatomy, and the surgeon's intra-operative judgement all factor into the decision. Mr Gormack will discuss the most appropriate approach for you at consultation.

Recovery

• Day 0–2 — standing same day, discharge within 1–2 nights
• Week 2 — many patients walking aid-free
• Week 6 — return to driving and office work
• Month 3+ — full functional recovery
