To validate the use of ultrasound in quantifying meniscal tissue across the anterior, middle, and posterior regions of both menisci (medial and lateral) in longitudinal and transverse planes by comparison with cadaveric dissection. Methods: A cross-sectional study was conducted on ten cryopreserved anatomical donors, obtaining a total of 120 ultrasound scans from the different meniscal regions. Following ultrasound imaging, cadaveric dissection was performed to facilitate photometric measurements, thereby enabling validation of the ultrasound findings. The intra-examiner reliability of the ultrasound measurements was also assessed. Results: The intra-examiner reliability of ultrasound measurements ranged from moderate to excellent. A strong and statistically significant positive correlation was observed between ultrasound and photometric measurements across all meniscal regions (r > 0.821; p < 0.05). In the medial meniscus, ultrasound visualized 99.1% of the anterior region (8.71 mm with ultrasound; 8.64 mm with photometry), 96.3% of the middle region (9.09 mm with ultrasound; 9.39 mm with photometry), and 98.5% of the posterior region (10.54 mm with ultrasound; 10.61 mm with photometry). In the lateral meniscus, ultrasound visualized 107.1% of the anterior region, 105.1% of the middle region, and 97.8% of the posterior region. The observed excess in tissue visualization in some regions likely reflects the inclusion of adjacent connective tissue, indistinguishable from meniscal tissue on ultrasound. Conclusions: Ultrasound is a valid and reliable modality for visualizing most meniscal tissue across regions, with a measurement discrepancy under 0.7 mm compared to anatomical dissection. However, caution is advised as adjacent connective tissue may sometimes be misidentified as meniscal tissue during evaluations. http://hdl.handle.net/11351/13463 Ecografia Menisc (Anatomia) Articulació femorotibial ANALYTICAL, DIAGNOSTIC AND THERAPEUTIC TECHNIQUES, AND EQUIPMENT::Diagnosis::Diagnostic Techniques and Procedures::Diagnostic Imaging::Ultrasonography Other subheadings::Other subheadings::/methods ANATOMY::Musculoskeletal System::Cartilage::Fibrocartilage::Meniscus::Menisci, Tibial Other subheadings::Other subheadings::/anatomy & histology ANATOMY::Musculoskeletal System::Skeleton::Joints::Knee Joint Other subheadings::Other subheadings::/anatomy & histology TÉCNICAS Y EQUIPOS ANALÍTICOS, DIAGNÓSTICOS Y TERAPÉUTICOS::diagnóstico::técnicas y procedimientos diagnósticos::diagnóstico por imagen::ecografía Otros calificadores::Otros calificadores::/métodos ANATOMÍA::sistema musculoesquelético::cartílago::fibrocartílago::menisco::meniscos tibiales Otros calificadores::Otros calificadores::/anatomía & histología ANATOMÍA::sistema musculoesquelético::esqueleto::articulaciones::articulación de la rodilla Otros calificadores::Otros calificadores::/anatomía & histología Validation of Ultrasound for Quantification of Knee Meniscal Tissue: A Cadaveric Study
