Validation of Non-Contact Anterior Cruciate Ligament Tears Produced by a Mechanical Impact Simulator Against the Clinical Presentation of Injury

摘要

Background:Anterior cruciate ligament (ACL) injuries are catastrophic events that impact athletic careers and lead to long-term, degenerative knee changes. As injuries are believed to occur within the first 50 msec following initial contact during a rapid deceleration task, impact simulators that rapidly deliver impulse loads to cadaveric specimens have been developed. However, no impactor has reproducibly and reliably created ACL injures in a distribution that mimics clinical observation.
