Abstract:
Objective To explore the effect of anterior cruciate ligament (ACL) rupture on the biomechanics of medial collateral ligament (MCL). Methods Six fresh human knee joints were fixed on the self-made fixture and flexed 90°. ACL was divided into a normal group, an anteromedi-al bundle(AMB) break group, and an ACL complete break group. 800N burden was loaded, and the MCL strain data were compared among the 3 groups. Results The MCL strain was significantly increased in the AMB break group and the ACL complete break group than that in the normal group (P<0.05). There was no significant difference in the MCL strain between the AMB break group and the ACL complete break group (P>0.05). Conclusion ACL rupture may cause significant changes in the MCL biomechanics, but the effect of AMB break and ACL complete break on MCL has no significant difference.
