Abstract
An anterior cruciate ligament (ACL) injury may be diagnosed by clinical examination
and radiological investigation using magnetic resonance imaging or by arthroscopy.1,2 Based on our experience, the ACL tear in concomitant chronic ACL and posterior cruciate
ligament (PCL) deficient knees may produce knee laxity, which is more difficult to
assess on clinical examination, which in turn may affect the management algorithm
of the patient. Our hypothesis is that, in a concomitant chronic ACL and PCL injury,
posterior capsular contracture and abnormal reattachment of torn ACL will result in
less clinical and subjective laxity, preoperatively. The aim of this study is to review
a cohort of patients who had undergone PCL reconstructive surgery and compare the
preoperative clinical assessments with and without anesthesia with arthroscopic finding
of ACL. This is to assess the accuracy and reliability of clinical ACL laxity tests
in detecting ACL tear in chronic ACL and PCL injury.
