Abstract
Reconstruction of the ACL (anterior cruciate ligament) requires precise anatomical placement of the tendon graft. Anatomic
variations may increase/decrease risk of the ACL rupture. Twenty-eight children with clinical, MRI and arthroscopic
verified ACL ruptures were compared with match case control group. MRI was done one to 12 months after trauma. The
thresholds values for identifying the ACL rupture were set; ACL angle <45°, Blumensat angle >0°, and the PCL angle
<115°. RESULTS: There was no significant difference of tibial attachment for the ACL and measured parameters of the femur.
The ACL angle (p<0.001), the Blumensat angle (p=0.001), and the PCL angle (p<0.001) were significantly different.
Each of the patients in group with a torn ACL had at least one parameter positive. DISCUSSION: ACL angle, Blumensat
angle and PCL angle might help to diagnose ruptured ACL. Pediatric patients with the ruptured ACL show no difference
in notch width or the tibial roof inclination angle as compared with pediatric patients without ACL rupture.
