ABSTRACT
PURPOSE:
To clarify the characteristic features of the meniscal root attachments, meniscofemoral ligaments (MFLs), and related osseous landmarks on three-dimensional images using computed tomography.METHODS:
Twenty-eight non-paired, formalin-fixed human cadaveric knees were evaluated in this study. The meniscal root attachments were identified and marked. Three-dimensional images were obtained after applying a contrast agent to the entire meniscal surfaces and MFLs, then the morphology of the meniscal root attachments and MFLs, and their positional relationships with osseous landmarks, were analyzed.RESULTS:
Parsons' knob divided the medial meniscal anterior root attachment and lateral meniscal anterior root attachment on the anterior portion of the tibial plateau. The medial meniscal posterior root attachment was near the medial intercondylar tubercle. The lateral meniscal posterior root attachment (LMPRA) was closer to the lateral intercondylar tubercle. Both root attachments were near the posterior intercondylar fossa. The positional relationships between the meniscal root attachments and related osseous landmarks were consistent in all specimens. The MFLs originated from the lateral meniscus posterior horn, and the anterior MFL was closer to the LMPRA than the posterior MFL. The posterior MFL originated at approximately the midpoint between the LMPRA and the most posterior margin of the lateral meniscus.CONCLUSION:
This study showed that the relationships between the characteristic features of the meniscal root attachments, MFLs, and related osseous landmarks were consistent. The clinical relevance of this study is that it improved understanding of the anatomy of the meniscal root attachments and MFLs.Palabras clave
