Arthroscopic anatomy and pathoanatomy of anterior cruciate ligament rupturesHussein, Mohsen (Avtor) Čretnik, Andrej (Avtor) Dinevski, Dejan (Avtor) Rupreht, Mitja (Avtor) Vogrin, Matjaž (Avtor) anterior cruciate ligament (ACL)insertion siterupture patternfootprint sizePurpose: To arthroscopically evaluate the size variability of the Anterior cruciate ligament (ACL) insertion sites and to determine whether there are variations in rupture patterns of the two ACL bundles. Material and Methods: Ninetyfour patients undergoing ACL reconstruction between June 2008 and June 2009 were included in our study. The average age of the patients was 26.7 +/- 8.3 years (range, 1648 years). Only patients with an ACL rupture less than 120 days old were included as unpublished data revealed difficulty in distinguishing between AM and PL bundles in older ACL ruptures.Results: The femoral ACL insertion site length ranged from 11 to 20 mm (15.9 +/- 2.2). On the tibial side, the length of the tibial ACL insertion site ranged from 9 to 20 mm (16.0 +/- 2.1). On the femoral side, the width of the ACL insertion site ranged from 6 to 11 mm (8.3 +/- 1.2). On the tibial side, the width of the entire ACL insertion site ranged from 6 to 12 mm (8.7 +/- 1.1). The most frequent injury pattern was found to be the proximal rupture of both bundles; seen in 74 patients (78.7%). Conclusion: Both hypotheses were confirmed, and this may be clinically relevant in anatomic ACL reconstruction.20132024-04-12 11:18:49Znanstveno delo88262sl
