Abstract：
Discoid lateral meniscus (DLM) is the most frequent congenital variant of the lateral meniscus, which is prone to degeneration and tears, and frequently causes knee osteoarthritis. The purpose of this article has been to analyze the publications made during 2023 on DLM. The main conclusions of the analysis were as follows: MRI assessment might be helpful to diagnose DLM and detect the presence of instability: two main factors in the decision to perform surgery. Arthroscopic assessment should be utilized in conjunction with MRI findings for complete DLM diagnosis. Restoring the normal shape, retaining adequate width and thickness, and ensuring the stability of the remnant DLM is essential to sustaining the physiological function of the meniscus and preserving the knee. Partial meniscectomy with or without repair should be the first-line treatment when feasible, given that the clinical and radiological long-run results of total or subtotal meniscectomy are worse.
摘要：
盘状外侧半月板（DLM）是外侧半月板最常见的先天性变异，容易退化和流泪，并经常导致膝骨关节炎。本文的目的是分析2023年期间有关DLM的出版物。分析的主要结论如下：MRI评估可能有助于诊断DLM和检测不稳定的存在：决定进行手术的两个主要因素。关节镜评估应与MRI检查结果结合使用，以进行完整的DLM诊断。恢复正常的形状，保持足够的宽度和厚度，并且确保残余DLM的稳定性对于维持半月板的生理功能和保持膝盖至关重要。如果可行，有或没有修复的半月板部分切除术应该是一线治疗，鉴于半月板全切除术或次全切除术的临床和放射学长期结果较差。
