Anterior cruciate ligament (ACL) tear is common injury in the knee. The aim of the study is to evaluate frequency of secondary changes of posterior cruciate ligament (PCL), medial (MCL) and lateral collateral ligament (LCL), and presence of meniscal lesions in chronic complete and partial tear of the ACL.

Retrospectively, in 55 patients with ACL complete and partial tear were evaluated MR images done six to nine months after injury (treated conservatively). Male were 44 (80%), and female 11 cases (20%) with mean age 35 years (range 13-63 y.). One group was with complete ACL tear(41 case-74.5%) and the other group was consisted of cases with partial tear of ACL (14 cases-25.5%). The location of ACL lesion was assessed. In both groups, presence of meniscal tear, PCL signal intensity (SI) changes and signs for...

Males are significantly younger (mean 32,1) compared to females (mean 41,6) (p<0,05). In 60% of the cases ACL lesion was localized at mid third, in 34.5% in distal third and only 5.5% have a lesion in proximal third. In 52.7% of the cases the signal intensity changes in PCL was present which is in correlation with lateral compartment cartilage degeneration (p<0.05). Medial meniscus lesion was present in 45 cases(81.8%), and most of them was localized at posterior horn (56.4%). In almost half of the cases...

The most common secondary change in patients with lesion on ACL is in medial meniscus-posterior horn.
