Introducción: La estructura histológica de los ligamentos, incluyendo el LCA, está compuesta por colágeno y elastina envueltos en una matriz de agua y proteoglicanos. El colágeno es el componente principal de los tendones y ligamentos, representa el 65 – 75% de su peso en seco. El objetivo del presente estudio es realizar una evaluación histopatológica de los fragmentos de LCA rotos tomados en el momento del acto quirúrgico por artroscopía.Material y métodos: Estudio prospectivo observacional sobre 50 casos con rotura de LCA. Se tomaron muestras de LCA en procedimiento artroscópico y se evaluó la histopatología del ligamento.Resultados: Se mencionan los resultados en base a resultados de anatomía patológica y evolución post operatoria.Conclusión: No se evidenciaron cambios degenerativos en la histopatología que justifiquen la rotura ligamentaria. Palabras claves: ligamento cruzado anterior, LCA, Histopatología, anatomía patológica.Nivel de evidencia: IV serie de casos. AbstractIntroduction: Histological structure of ligaments, including the anterior cruciate ligament, is composed of collagen and elastin wrapped in a matrix of water and proteoglycans. Collagen is the main component of tendons and ligaments, accounting for 65-75% of its dry weight. The aim of the present study is to perform a histopathological evaluation of the ruptured anterior cruciate ligament fragments taken at the time of surgical procedure by arthroscopy.Methods: A prospective observational study of 50 cases with anterior cruciate ligament rupture. Anterior cruciate ligament samples were taken in an arthroscopic procedure and histopathology of the ligament was evaluated.Results: Pathology results and post-operative evolution are mentioned.Conclusion: Degenerative changes were observed in the histopathology exam; it cannot be demonstrated if these changes are previous or posterior to ligament rupture.
