The technique
An incision is made on the front of the thigh, then the surgeon passes between the muscles to reach the hip joint without cutting any tendons. The femoral head is delivered, and the new ball and socket are implanted through the same window.
Benefits
- Shorter hospital stay — typically 1–2 nights compared with 2–3 for other approaches.
- Faster recovery of balance and walking — many patients are walking aid-free within 2 weeks.
- Lowest dislocation rate of any approach — 0.2–0.5%, compared with around 1% for traditional approaches.
- No formal hip precautions after surgery.
- Smaller, more cosmetic scar.
Risks specific to this approach
- Lateral femoral cutaneous nerve injury — causing numbness over the outer thigh in a proportion of patients. Usually settles, but can be permanent.
- Slightly elevated risk of femoral fracture (under 0.5%).
- General hip replacement risks apply (see the hip replacement page).
Is it right for you?
The anterior approach is not suitable for every patient. Body habitus, hip anatomy and the type of pathology all influence the decision. Mr Gormack will discuss which approach is best for you at your consultation.
