Deltoid (triangular)-shaped anterior cruciate ligament that caused notch impingement: a report of two cases

      Abstract

      In this article, we present 2 previously unreported cases of anterior cruciate ligaments (ACL) that had a wide deltoid (triangular)-shaped tibial insertion in the coronal plane that caused impingement at the intercondylar notch, inferior parts of patellofemoral sulcus, and the posterior cruciate ligament (PCL). Ligamentoplasty was used in both cases. Inferomedial and inferolateral parts of the ACL that caused impingement were excised, and the normal width of the tibial insertion of the ACL was provided.
