BACKGROUND: Second anterior cruciate ligament (ACL) tears after reconstruction occur at a reported rate of 20% to 30%. This high frequency indicates that there may be factors that predispose an athlete to graft failure and ACL tears of the contralateral knee. PURPOSE: To determine the incidence of second ACL injuries in a geographic population-based cohort over a 10-year observation period. STUDY DESIGN: Descriptive epidemiological study. METHODS: International Classification of Diseases, 9th Revision (ICD-9) codes relevant to the diagnosis of an ACL tear and the procedure code for ACL reconstruction were searched across the Rochester Epidemiology Project, a multidisciplinary county database, between the years of 1990 and 2000...

BACKGROUND: Anatomic ACL surgery, including double bundle ACL reconstruction, has been investigated widely. The purpose of this study was to gain insight in the currently used surgical management of anterior cruciate ligament injuries amongst Belgian orthopaedic surgeons. METHODS: A survey consisting of epidemiological questions, ACL surgery related questions and questions concerning rehabilitation was submitted to all members of the Belgian Knee Society. RESULTS: Anatomic single bundle ACL repair with transportal femoral tunnel drilling, using an autologous hamstring graft fixed with a cortical suspension system proximal and an interference screw distal is currently the most common technique...

CONTEXT: Epidemiological data demonstrate the need for lower-extremity injury-prevention training. Neuromuscular-control (NMC) programs are immediately effective at minimizing lower-extremity injury risk and improving sport-related performance measures. Research investigating lasting effects after an injury-prevention program is limited. OBJECTIVE: To determine whether dynamic balance, landing mechanics, and hamstring and quadriceps strength could be improved after a 6-wk NMC intervention and maintained for a season...
