Abstract (may include machine translation)

BACKGROUND:
Rupture of the anterior cruciate ligament (ACL) is one of the most common knee injuries and has substantial impact on knee function. Beside primary ruptures, an increasing number of re-(re-)ruptures occur, representing a therapeutical challenge for the treating surgeon. Several risk factors for re-ruptures have been previously identified, including an increased tibial slope.
OBJECTIVE:
In this study, we investigated the effect of femoral condyle configuration on ACL-ruptures and re-ruptures.
METHODS:
In-vivo magnetic resonance imaging scans of three different groups of patients were compared. Group 1 included patients with an intact ACL on both sides, group 2 included patients with primary, unilateral ACL-rupture, while group 3 included patients with an ACL-re-rupture or re-(re-)rupture. Fourteen different variables were obtained and analyzed regarding their impact on ACL-re-(re-)rupture.
RESULTS:
Overall, 334 knees were investigated. Our data allowed us to define parameters to identify anatomical configurations of bones associated with an increased risk of ACL-re-rupture. Our results show, that patients with ACL-re-rupture show increased radii of the extension facet of the lateral femoral condyle (
0.001) as well as of the extension facet of the medial femoral condyle (
0.001).
CONCLUSION:
We conclude that a spherical femoral condyle form does influence the clinical outcome after ACL-reconstruction.
