- Primary Outcome Measures
Name Time Method Quantify the loss of extension associated with tensioning the ACL graft with the knee in full extension versus in flexion. Preoperative extension and flexion of operative and non-operative knee will be assessed under anaesthesia using a digital inclinometer. Using computer navigation intraoperatively, the knee extension range and tibiofemoral rotation in full extension will be measured. Post operative assessments will be repeated using the same assessment method as performed preoperatively.[Day 0 (Day of surgery)]
- Secondary Outcome Measures
Name Time Method To quantify the anterior laxity of the knee after ACL reconstruction and assess whether the native knee laxity has been restored (by comparing with the non-operative knee). Preoperative anterior tibial translation (of both knees) will be performed using a Rolimeter). Post operative assessments will be repeated using the same assessment method as performed preoperatively.[Day 0 (Day of Surgery)];To quantify the rotational constraint of the knee after ACL reconstruction and assess whether the native rotational constraint has been restored (by comparing with the non-operative knee). On the operative limb, graded pivot shift test will be performed preoperative and immediately post-operative.[Day 0 (Day of Surgery)]
