Abstract：
OBJECTIVE: The purpose of the present study was to perform a survey administered to members of the Meniscus International Network (MenIN) Study Group, seeking to delineate the most contentious aspects of meniscal extrusion classification and provide a foundation for new, more comprehensive definitions and treatments for these pathologies.
METHODS: MenIN Study Group is a group of international experts treating and performing research on meniscus pathology and treatment. All MenIN Study Group members were asked to complete a survey aimed at establishing criteria for the optimal classification system for meniscal extrusion. Data obtained from the completed questionnaires were transferred into a spreadsheet and then analysed. All responses are presented as counts, percentages or means.
RESULTS: Forty-seven (85.5%) MenIN Study Group members completed the survey and were included in this analysis. Key aspects recommended for inclusion in a comprehensive classification system for meniscal extrusion included laterality (93.6%), anatomical location (76.6%), patient age (76.6%), body mass index (BMI) (68.1%) and aetiology (68.1%). For classifying meniscal extrusion, 53.2% considered the distance in millimetres from the tibial plateau\'s outer margin as the most reliable measurement technique on imaging. Preferences for imaging modalities varied, with 44.7% favouring weight-bearing magnetic resonance imaging (MRI) and 36.2% opting for weight-bearing ultrasound due to its greater availability. Respondents advocated for a classification system addressing stability or progression of meniscal extrusion (66%), reducibility (53.2%), potential progression of knee osteoarthritis (OA) (83%), influencing treatment approaches (83%), a gradation system (83%), consideration of dynamic factors (66%), association with clinical outcomes and prognosis (76.6%) and investigation around centralization procedures (57.4%).
CONCLUSIONS: In conclusion, the findings of this survey shed light on the global perspectives regarding meniscal extrusion classification. It was generally felt that a new classification of extrusion measured on MRI scans at the mid-tibial plateau should be developed, which considers factors such as laterality, anatomical location, age, BMI and aetiology. Additionally, the results support the integration of dynamic factors and clinical outcomes in MRI-based classifications to inform treatment approaches.
METHODS: Level IV.

摘要：
目的：本研究的目的是对半月板国际网络（MenIN）研究小组的成员进行调查，试图描绘半月板挤压分类中最具争议的方面，并为新的，更全面的定义和治疗这些疾病。
方法：MenIN研究组是一组治疗和进行半月板病理和治疗研究的国际专家。所有MenIN研究小组成员都被要求完成一项旨在建立半月板挤压最佳分类系统标准的调查。从完成的问卷中获得的数据被转移到电子表格中，然后进行分析。所有的回答都以计数表示，百分比或平均值。
结果：47名（85.5%）MenIN研究小组成员完成了调查并被纳入本分析。建议纳入半月板挤压综合分类系统的关键方面包括侧向性（93.6％），解剖位置（76.6%），患者年龄（76.6%），体重指数（BMI）（68.1%）和病因（68.1%）。为了对半月板挤压进行分类，53.2%的人认为距胫骨平台外缘的距离(毫米)是最可靠的成像测量技术。成像模式的偏好各不相同，其中44.7％的人赞成负重磁共振成像（MRI），36.2％的人选择负重超声，因为它的可用性更高。受访者主张采用分类系统来解决半月板挤压的稳定性或进展（66％），可还原性（53.2%），膝骨关节炎（OA）的潜在进展（83％），影响治疗方法（83%），分级系统(83%)，考虑动态因素(66%)，与临床结果和预后的关联（76.6％）和集中程序的调查（57.4％）。
结论：结论：这项调查的结果揭示了关于半月板挤压分类的全球观点。人们普遍认为，应该对胫骨中部平台的MRI扫描测量的挤压进行新的分类，其中考虑了诸如侧向性等因素，解剖位置,年龄,BMI和病因。此外,结果支持将动态因素和临床结局整合到基于MRI的分类中,为治疗方法提供信息.
方法：四级。
