Relações anatômicas entre as inserções femorais dos ligamentos meniscofemoral de Wrisberg e cruzado posterior

Abstract

ResumoObjetivoAvaliar a frequência e a morfometria do ligamento meniscofemoral de Wrisberg e a relação de suas inserções femorais com aquelas do ligamento cruzado posterior (LCP).Desenho do estudoEstudo laboratorial controlado.MétodosForam feitas dissecções minuciosas das inserções femorais dos ligamentos de Wrisberg (LW) e do LCP em 24 peças anatômicas de joelhos. As peças foram fotografadas com uma câmera digital e marcador milimetrado; o programa Image J foi usado para medir a área das inserções ligamentares, em milímetros quadrados.ResultadosO LW esteve presente em 91,6% das peças estudadas. Nessas, seu formato foi elíptico em 12 peças (54,54%). Em 68% dos joelhos a inserção do LW esteve proximal à crista intercondilar medial, próximo à banda posteromedial do LCP. A área média da inserção femoral do LW foi de 20,46±6,12mm2, o que correspondeu a 23,3% da área de inserção do LCP.ConclusõesO LW é estrutura frequente nos joelhos, com grande variabilidade de sua área média. Proporcionalmente ao LCP, sua área média sugere que esse ligamento pode contribuir para a estabilidade posterior do joelho.AbstractObjectiveTo evaluate the frequency and morphometry of the Wrisberg's ligament and its relationships with the posterior cruciate ligament's femoral insertion.Study designControlled laboratory study.Methods24 unpaired knee pieces, 12 right and 12 left were submitted to a deep dissection of the Wrisberg and posterior cruciate ligaments. The pieces were photographed with a digital camera and ruler; the Image J software was used to measure the ligaments’ insertion areas, in square millimeters.ResultsThe Wrisberg ligament was present in 91.6% of the studied pieces. In those its shape was elliptical in 12 pieces (54.54%). In 68% of the knees, the WL insertion was proximal to the medial intercondilar ridge, close to the PCL posteromedial bundle.The average area for the WL was 20.46±6.12mm2. This number corresponded to 23.3% of the PCL's average area.ConclusionsWL ligament is a common structure in knees. There is a wide variation of its insertion area. Proportionally to the PCL's insertion area the WL one's suggests that it may contribute to the posterior stability of the knee joint.
