Abstract
Introduction:
A review of the literature demonstrates that injury of the lateral meniscus, anterolateral capsule, and iliotibial(IT ) band or small lateral tibial plateau aggravate the instability of knee and contributes to a high-grade pivot shift in the ACL-deficient knee.
Hypotheses:
The hypothesis was that disruption of posterior root of the lateral meniscus will further destabilize the ACL-deficient knee and simulated a high-grade pivot shift but posterior root of medial meniscal not.
Methods:
6 fresh-frozen cadaveric knees was performed the next test in a custom activity simulator.1.Determine the effect of PRLMT on the stability of ACL-deficient knee.In the pivot shift test, ITB force (50, 75, 100, 125, 150, and 175 N), internal rotation moments (1, 2, and 3 N.m),and valgus moments (5 and 7 N.m). tibial translation of front drawer test were performed by applying a 90-N anterior
