AB  - INTRODUCTION: The effect of leg dominance on anterior cruciate ligament (ACL) 
      injuries has been studied with some studies noting a propensity for injuries in 
      the non-dominant leg. Its effect on post-ACL reconstruction recovery, however, is 
      not well known. The authors hypothesize that dominant limb injuries undergo 
      rehabilitation faster and positively affect early functional outcome scores and 
      return to sports and set about studying these effects. METHODS: This is a 
      retrospective study of 254 patients from a single institution who underwent ACL 
      reconstruction for acute ACL ruptures and the results were compared between 
      patients with dominant and non-dominant limb injuries. Objective measurements 
      including the KT-1000, single-leg hop distance and Biodex knee extension peak 
      torque were used to evaluate recovery. Pre- and post-operative functional outcome 
      scores such as the International Knee Documentation Committee (IKDC), Tegner 
      activity score and Lysholm knee scale were documented. RESULTS: Early functional 
      outcomes were similar. Minimal clinically important difference (MCID) improvement 
      in IKDC scores was achieved in 69.7% of the dominant versus 66.0% of the 
      non-dominant injury group (p = 0.99), 75.2% versus 79.6% (p = 0.45) for the 
      Lysholm knee scale, and 81.6% versus 84.9% (p = 0.50) for the Tegner activity 
      score. The majority of patients in both subgroups had a return of at least 80% of 
      peak knee flexion and extension peak torque at 5.4 months post-operatively; 92.9% 
      of subjects with a non-dominant leg injury and 87.2% with a dominant leg injury 
      had returned to their pre-injury sports 1 year from surgery. CONCLUSIONS: Results 
      from this study suggest that despite theoretical differences, leg dominance does 
      not have a significant impact on short-term functional outcomes and return to 
      sports. Objective measurements suggest that limb strength recovers at a 
      comparable rate. Injuries to either leg demonstrate equally positive improvement 
      post-ACL reconstruction given the same post-operative rehabilitation. LEVEL OF 
      EVIDENCE: III, retrospective comparative study. LEVEL OF EVIDENCE: III, 
      retrospective cohort study.
