The aim of this anatomical study was to describe the anatomy of the meniscal roots and their relationships with respect to the main adjacent structures in order to improve their surgical reconstruction.
Fourteen knees were included. The mean age of the donors was 92 years (range 89-96). We studied the general characteristics of the anterior and posterior roots of the medial meniscus and lateral meniscus by measuring their widths at their base and area. We investigated the relations between anterior and posterior roots of the medial and lateral menisci with respect to the anterior and posterior cruciate ligaments (ACL and PCL).
The mean width of the anterior root of the lateral meniscus was 10.5 ± 1.4 mm. The mean width of the anterior root of the medial meniscus was 10 ± 1.5 mm. The mean width of the posterior root of lateral meniscus was 11.4 ± 1.4 mm. The mean width of the posterior root of medial meniscus was 10.5 ± 1.0 mm. The mean distance between the anterior cruciate ligament and the anterior root of lateral meniscus was 9.8 ± 2.9 mm, for the medial meniscus it was 15.9 ± 3.4 mm. The mean distance between the posterior cruciate ligament and the posterior root of the lateral meniscus was 11.5 ± 2.7 mm, for the medial meniscus, it was 11 ± 2.6 mm.
The anterior and posterior meniscal roots have precise landmarks, and this article contributes to define the location of the meniscal roots with respect to their adjacent anatomical structures: ACL, PCL and intercondylar tubercle. Having precise measures of the distances between the meniscus roots and these structures allows knee surgeons to perform ACL reconstruction, meniscal root repair and meniscal allograft transplantation.
本解剖研究旨在描述半月板根部的解剖结构及其与主要相邻结构的关系，以改善半月板根部的外科重建。
纳入 14 例膝关节。供体的平均年龄为 92 岁（范围 89-96 岁）。我们通过测量半月板根部的基底宽度和面积来研究内侧和外侧半月板前、后根部的一般特征。我们研究了内侧和外侧半月板的前、后根部与前、后交叉韧带（ACL 和 PCL）之间的关系。
外侧半月板前根部的平均宽度为 10.5±1.4mm。内侧半月板前根部的平均宽度为 10±1.5mm。外侧半月板后根部的平均宽度为 11.4±1.4mm。内侧半月板后根部的平均宽度为 10.5±1.0mm。前交叉韧带与外侧半月板前根部之间的平均距离为 9.8±2.9mm，内侧半月板为 15.9±3.4mm。后交叉韧带与外侧半月板后根部之间的平均距离为 11.5±2.7mm，内侧半月板为 11±2.6mm。
前、后半月板根部有明确的解剖标志，本文有助于确定半月板根部相对于其相邻解剖结构（ACL、PCL 和髁间棘）的位置。精确测量半月板根部与这些结构之间的距离，可使膝关节外科医生进行 ACL 重建、半月板根部修复和半月板同种异体移植。
