Anterior cruciate ligament (ACL) reconstruction effectively eliminates the clinical knee instability associated with ACL injury. As arthroscopic reconstruction techniques continue to yield excellent clinical results and low patient morbidity, the number of patients undergoing this procedure continues to increase. Unfortunately, a significant proportion of these patients will report unsatisfactory outcomes after primary ACL reconstruction. Poor functional outcomes are generally associated with one or more of the following clinical problems: persistent knee pain, knee motion loss, or recurrent anterior knee instability. The etiology of failure must be clearly defined before the development of a treatment plan. Thus, a systematic approach is recommended in the evaluation of the failed ACL reconstruction patient. Herein, we describe our experience at the Hospital for Special Surgery in the evaluation and treatment of individuals who failed primary ACL reconstruction.
