Isolated Meniscotibial Ligament Rupture: The Medial Meniscus "Belt Lesion".

ABSTRACT: Ramp lesions play a major role in both anteroposterior and rotational instability following anterior cruciate ligament rupture. The meniscotibial ligament (MTL) is the most important structure to repair and is the primary stabilizer of the posterior horn of the medial meniscus. The posteroinferior insertion of the MTL on the posterior horn of the medial has been described, forming a posterior "belt." Isolated MTL lesion diagnosis can be challenging, as the absence of a meniscocapsular ligament lesion prevents its correct visualization through transnotch vision. This article details a technique to diagnose and repair the "belt lesion" of the medial meniscus.

Project description:BackgroundOnly limited data are available regarding postural stability between anterior cruciate ligament (ACL)-injured patients with medial meniscus (MM) tear and those with lateral meniscus (LM) tear. The purpose of this study was to compare preoperative postural stability for both involved and uninvolved knees in ACL rupture combined with MM and LM tears. It was hypothesized that there would be a significant difference in postural stability between these two groups.MethodsNinety-three ACL-injured patients (53 combined with MM tears vs. 40 combined with LM tears) were included. Static and dynamic postural stability were evaluated with the overall stability index (OSI), anterior–posterior stability index (APSI), and medial–lateral stability index (MLSI) using stabilometry. Knee muscle strength was evaluated using an isokinetic testing device.ResultsIn the static postural stability test, none of the stability indices showed significant differences between the two groups for both knees (p?>?0.05). In the dynamic postural stability test for involved side knees, the OSI and APSI were significantly higher in the LM tear group compared to the MM tear group (OSI: 2.0?±?0.8 vs. 1.6?±?0.5, p?=?0.001; APSI: 1.5?±?0.6 vs. 1.3?±?0.5, p?=?0.023), but not the MLSI (p?>?0.05). In the static and dynamic postural stability tests in each group, there were no significant differences between the involved and uninvolved side knees (p?>?0.05). There was no significant difference in the knee muscle strength between the two groups (p?>?0.05). All postural stability showed no significant correlation with knee muscle strength (p?>?0.05).ConclusionDynamic postural stability was poorer in patients with ACL rupture combined with LM tear than in those with MM tear. Therefore, close monitoring for postural stability would be necessary during preoperative and postoperative rehabilitation, especially for patients with ACL rupture combined with LM tear.Level of evidence: Level III
