A 22-year-old footballer sustains a non-contact deceleration injury to the knee with an audible 'pop', immediate haemarthrosis, and a positive Lachman test. MRI confirms complete ACL rupture without concomitant meniscal or cartilage injury. He wants to return to competitive football. The recommended time to return to sport after ACL reconstruction is at least:
- A 3 months — based on structural graft healing
- B 6 months — minimum functional milestone-based return-to-sport protocol
- C 9–12 months — based on graft ligamentisation, neuromuscular recovery, and psychological readiness assessments ✓
- D 12–18 months for all young athletes to minimise re-rupture risk
Correct answer: C. 9–12 months — based on graft ligamentisation, neuromuscular recovery, and psychological readiness assessments
Explanation
Current evidence-based guidelines recommend a minimum of 9–12 months before return to competitive pivoting sport after ACL reconstruction, as graft ligamentisation (remodelling of the transplanted tendon into a functional ligament) is largely incomplete before 9 months. Returning at 6 months doubles the re-rupture risk compared to 9 months. Return should also be criterion-based, incorporating limb symmetry indices on strength testing (> 90%), hop tests, and psychological readiness (ACL–RSI score), not time-based alone.
