Primary outcomePrimary: International Knee Documentation Committee (IKDC) Questionnaire Score — 47.40; 50.80; 61.83; 52.86 score on a scale — p=0.0219
Summary
The main objective is to determine the impact of Blood Flow Restriction (BFR) therapy, in comparison to a standard rehabilitation protocol, on preventing atrophy, improving quadriceps strength and improving functional outcomes of patients recovering from ACL reconstruction. The investigators hypothesize that patients undergoing BFR therapy after ACL reconstruction surgery will have better functional outcomes than those undergoing normal rehabilitation without BFR therapy.
