“…Our previous cadaveric analyses demonstrated a mean difference of only 0.25 mm when comparing ME values when measured with the 2 modalities. 13 , 17 The desire to use ultrasound for ME stems from its practicality, ability for weight-bearing measurements, and affordability. There have been several studies that have even reported its utility for measuring ME after medial meniscus allograft transplantation and identifying patients with lateral discoid menisci.…”

“…The displacement of the meniscus induces biomechanical alterations in the knee joint, which have the potential to instigate progressive cartilage damage, ultimately leading to osteoarthritis (OA) [14]. Meniscal root lesions are frequently cited as a primary causative factor for meniscal extrusion [10,11], with surgical repair becoming a standard of care amongst specialized knee surgeons. However, the pathomechanism of meniscal extrusion is complex, with some authors reporting degenerative changes and other pathology affecting the meniscus stability leading to meniscal extrusion ultimately leading to meniscal root tear [12,18,19].…”

PurposeThe 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.MethodsMenIN 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.ResultsForty‐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%).ConclusionsIn 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.Level of EvidenceLevel IV.
