Failed reconstruction of the anterior cruciate ligament (ACL) in a young, active patient represents a difficult clinical problem. Numerous factors contribute to failure, including repeat trauma, technical errors, biologic influences, or a combination of causes. Technical errors commonly include femoral and tibial tunnel malposition, inadequate graft fixation, failure to address associated poste...

Severe metallosis following medial unicompartmental knee arthroplasty (UKA) is relatively rare. It is usually due to long-standing wear of the polyethylene component, resulting in frictional wear between the femoral and tibial metallic components. Biomechanical and cadaveric studies have shown the effects of anterior cruciate ligament (ACL) transection following medial UKA. We describe a case o...

BACKGROUND Skiing and snowboarding have become increasingly popular since the inception of the winter X-Games in 1997. PURPOSE To determine (1) rate of return to sport (RTS) to the winter X-Games following anterior cruciate ligament (ACL) reconstruction and (2) performance upon RTS following ACL reconstruction. HYPOTHESES There is a high rate of RTS to the winter X-Games in subjects undergo...

INTRODUCTION Traditional anterior cruciate ligament (ACL) surgery has demonstrated good results, but there is still a subset of unsatisfactory outcomes. Trends in reconstruction technique have changed from bone-patella-tendon-bone to hamstring refixation, and the next step appears to be the double bundle concept. METHODS We examined six fresh-frozen cadaver knees to evaluate the double bundle...

BACKGROUND Revision anterior cruciate ligament (ACL) reconstruction requires a precise evaluation of previous tunnel locations and diameters. Enlargement of the tunnels, despite not usually affecting primary reconstruction outcomes, plays an important role in revision ACL management. Three dimensional (3D) computed tomography (CT) models are reported to be the most accurate method for identifyi...

BACKGROUND The reported rate of second anterior cruciate ligament (ACL) injuries (20%-30%), including graft failure and contralateral ACL tears, after ACL reconstruction (ACLR) or nonoperative therapy indicates that multiple factors may predispose patients to subsequent ACL injuries. PURPOSE To determine the incidence of second ACL injuries in a population-based cohort over a 10-year observat...

Arthroscopically assisted anterior cruciate ligament (ACL) reconstruction has been performed at Rush Medical Center since January 1986. Since then, over 3000 arthroscopically assisted ACL reconstructions have been performed at this institution by the 2 senior authors. The surgical procedure has evolved from a 2-incision technique to a single-incision technique. The graft of choice has been auto...

PURPOSE To compare the incidence of bacterial infection in anterior cruciate ligament (ACL) reconstruction with autograft versus allograft. METHODS We completed a retrospective medical record review of ACL reconstructions performed at our institutions between 2001 and 2005. These included 170 autograft, 628 allograft, and 3 combined autograft/allograft reconstructions. Data collection include...
