Outcome measures included radiographic analysis, International Knee Documentation Committee Subjective Knee Evaluation Form (IKDC), KT\u20101000, Tegner Activity Level Scale, Lysholm Knee Score, ACL quality of life score (ACL\u2010QOL) and knee flexor\/extensor strength.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Seventy\u2010four patients consented and sixty\u2010eight (43\u00a0male, 25 female) were included for analysis. Average age (SD) at the time of surgery was 31.2 (\u00b19.1) years. At follow\u2010up of 14.6 (1.9) years, 9 % had re\u2010ruptured their ACL, whereas 5 % ruptured the contralateral ACL.

Medial meniscus surgery was a strong predictor of OA. Seventy\u2010five per cent scored a normal or nearly normal knee on the IKDC.
