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 degrees . ACL was divided into a normal group, an anteromedial 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). CONCLUSIONS 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.

D013180 Sprains and Strains A collective term for muscle and ligament injuries without dislocation or fracture. A sprain is a joint injury in which some of the fibers of a supporting ligament are ruptured but the continuity of the ligament remains intact. A strain is an overstretching or overexertion of some part of the musculature. Sprains,Strains,Sprain,Strain,Strains and Sprains
