英文摘要

This study investigated the effect of damage of the posterior and anterior horns of the medial meniscus on knee stability.

Twenty fresh-frozen porcine knees were divided into two groups (anterior horn and posterior horn injury). Each group was tested in three states: intact medial meniscus, posterior or anterior horn of medial meniscus resection and total medial meniscectomy. A robotic testing system was used to test anterior tibial translation (ATT) at 30A degrees (full extension), 60A degrees and 90A degrees of knee flexion with an external anterior tibial load of 89 N, internal rotation (IR) and external rotation (ER) at 30A degrees and 60A degrees of knee flexion under a 4 N m tibial rotation torque.

In response to an IR torque, there was a significant difference between the state of intact medial meniscus and anterior and posterior horn damage, except for anterior horn resection at 60A degrees of knee flexion. In response to an ER torque, there were no significant differences between the state of intact meniscus and horn damage except for anterior horn resection at 30A degrees of knee flexion. Meniscal damage had no significant effect on ATT.

The results indicated that the posterior horn was more important in controlling the IR stability than the anterior horn with knee flexion, and the anterior horn was more important in controlling the ER stability than the posterior horn at full knee extension in the anterior cruciate ligament-intact knee. These findings further the understanding of the mechanisms, the prevention of injuries and rehabilitation of meniscal horn injury in clinical practice.
