Abstract:
Ligament injuries of the knee joint are very common among competitive athletes. Acrurate assessment ot the nature of these injuries is a prerequisite for appropriate therapy. The purpose of this study is to evaluate the significance of MRI findings in assesing the status of ACL tear and associated injuries. 31 cases of ACL injuries were examined and reconstructed arthroscopically from Jan. 1997 to Sep. 1997 at Kyung Hee University Hospital. 1n all cases, we reviewed preoperative physical and MRI findings and performed postoperative radiologic assessments. Results were as follows; 1. Lachman test and Pivot shift test were positive in all 31 cases but anterior drawer test was positive in 29 case,s. 2. In MRI findings, 24 cases were interpretated as complete ACL tear and / cases as inccomplete ACL tear. But these 7 cases were confirmed as complete tear in mthroscopic exanunation with careful probing of ACL fiher. 3. MRI showed associated meniscal injuries in 19 cases(61%)-14 cases(74%) at medial meniscus, 5 cases(26%) at lateral meniscus. All cases were confirmed arthroscopically. In conc1usion, physical findings are more reliable than MRI findings in diagnosing the complete ACL tear and deciding the ACL reconstruction. But MRI findings are very helpful to assess the associated injuries and plan the treatments.
