Primary Outcome Measures

Name	Time	Method
Anterior knee stability is measured using the Lachman test at baseline, 6, 12 and 24 months post-operatively.

Secondary Outcome Measures

Name	Time	Method
1. Pain is measured using the visual analogue scale (VAS) at baseline, 6, 12 and 24 months post-operatively<br>2. Patient-reported outcome is measured using the Lysholm and Tegner score (questionnaire) baseline, 6, 12 and 24 months post-operatively<br>3. Knee muscle strength is measured using a dynamometer at baseline, 6, 12 and 24 months post-operatively<br>4. Balance, speed and strength of the lower limb are measured using the Back in action test battery at baseline, 6, 12 and 24 months post-operatively<br>5. Osteoarthritis is measured using x-ray (Kellgren and Lawrence score) at 24 months post-operatively
