【摘要】：目的:统计测量外侧半月板后根部损伤(Posterior Lateral meniscus root lesion,PLMRL)病例中半月板股骨韧带(Meniscofemoral ligament,MFL)完整型和MFL缺失型的外突发生率和外突值,探讨半月板股骨韧带对外侧半月板外突的影响。方法:本研究为回顾性病例对照研究。2013年1月至2015年1月于本院进行关节镜手术的病例中,选取存在外侧半月板后根部损伤的病例作为研究对象。通过MRI评估和关节镜资料确定入选病例的损伤类型,并按改良的Peterson分型分为MFL完整组和MFL缺失组。选取同期进行前交叉韧带重建手术而外侧半月板正常的病例作为对照组。测量各组半月板外突值,并统计各组外突发生率和外突值的差异。结果:共有72例病例入选本研究,其中MFL完整型56例,外突发生率为30.4%,外突均值为0.44±0.11 mm;MFL缺失型为16例,外突发生率为100%,外突均值为1.95±0.21 mm;匹配对照组56例,外突发生率为1.8%,外突均值为0.40±0.20 mm。MFL完整组和对照组的外突均值无显著差异(P=0.823),MFL缺失组的外突均值要显著大于MFL完整组(P0.001)和对照组(P0.001)。结论:半月板股骨韧带对限制外侧半月板外突有重要作用。外侧半月板后根部损伤时,MFL完整型并不出现明显的半月板外突,而MFL缺失型则会出现明显的半月板外突。
[Abstract]:Objective: to measure the incidence of lateral meniscus femoral ligament (Meniscofemoral ligament,MFL) intact type and MFL deletion type in patients with lateral meniscus posterior root injury (Posterior Lateral meniscus root lesion,PLMRL). To investigate the effect of meniscal femoral ligament on lateral meniscus process. Methods: this study was a retrospective case-control study. From January 2013 to January 2015 in our hospital, cases with posterior root injury of lateral meniscus were selected as subjects. The injury types of the selected cases were determined by MRI evaluation and arthroscopic data. According to the modified Peterson classification, the patients were divided into two groups: MFL complete group and MFL deletion group. Patients with normal lateral meniscus and anterior cruciate ligament reconstruction were selected as control group. Meniscus external protrusion value was measured in each group, and the incidence and exophthalmos value of each group were statistically analyzed. Results: a total of 72 cases were enrolled in this study. Among them, 56 cases were MFL intact type, the incidence of exoid process was 30.4%, the mean value of exoid process was 0.44 卤0.11 mm;MFL deletion type in 16 cases, the rate of exoid process was 100%, and the mean value of exoid process was 1.95 卤0.21 mm;. There was no significant difference between the control group (P < 0. 823) and the control group (P < 0. 823). There was no significant difference between the matched control group (56 cases) and the control group (P < 0. 823). The mean exoid of MFL deletion group was significantly higher than that of MFL intact group (P0.001) and control group (P0.001). Conclusion: meniscal femoral ligament plays an important role in limiting the lateral meniscus process. When the posterior root of the lateral meniscus was injured, the intact type of MFL did not appear the obvious meniscus exoid, but the MFL deletion type showed the obvious meniscus exoid.
