Failure of a primary anterior cruciate ligament (ACL) reconstruction is associated with poor functional outcomes even after revision surgery. The aim of this study is to identify early predictors for failure, so that it may aid in recognition of at-risk patients. An observational study was conducted of 623 patients undergoing primary ACL reconstruction by a single surgeon over a 72 month period. Patient and procedure related parameters including age, gender, BMI, time to surgery, graft size, fixation methods, meniscal and chondral injuries, meniscal surgery, radiological parameters and post-operative IKDC scores. Logistic regression modeling was employed to identify those factors which were statistically significant for failure.AIM
