Quantification of the overall anterior cruciate ligament (ACL) and anteromedial (AM) and posterolateral (PL) bundle centers in respect to arthroscopically pertinent bony and soft tissue landmarks has not been thoroughly assessed.
A standardized anatomical measurement method can quantitate the locations of the ACL and AM and PL bundle centers in reference to each other and anatomical landmarks.
Descriptive laboratory study.
Quantification of the ACL and its bundle attachments was performed on 11 cadaveric knees using a radio frequency-tracking device.
The tibial ACL attachment center was 7.5 mm medial to the anterior horn of the lateral meniscus, 13.0 mm anterior to the retro-eminence ridge, and 10.5 mm posterior to the ACL ridge. The femoral ACL attachment center was 1.7 mm proximal to the bifurcate ridge and 6.1 mm posterior to the lateral intercondylar ridge. The tibial AM attachment center was 8.3 mm medial to the anteromedial aspect of the lateral meniscus anterior horn, 17.8 mm anterior to the retro-eminence ridge, and 5.6 mm posterior to the ACL ridge. The femoral AM attachment center was 4.8 mm proximal to the bifurcate ridge and 7.1 mm posterior to the lateral intercondylar ridge. The tibial PL bundle attachment center was 6.6 mm medial to the posteromedial aspect of the lateral meniscus anterior horn, 10.8 mm anteromedial to the root attachment of the lateral meniscus posterior horn, and 8.4 mm anterior to the retro-eminence ridge. The femoral PL bundle attachment center was 5.2 mm distal to the bifurcate ridge and 3.6 mm posterior to the lateral intercondylar ridge.
The authors developed a comprehensive compilation of measurements of arthroscopically pertinent bony and soft tissue landmarks that quantitate the ACL and its individual bundle attachment centers on the tibia and femur.
These clinically relevant arthroscopic landmarks may enhance single- and double-bundle ACL reconstructions through improved tunnel placement.
尚未全面评估关节镜相关骨和软组织解剖标志的前交叉韧带（ACL）和前内（AM）及后外（PL）束中心的整体定量。
一种标准化的解剖测量方法可以定量评估 ACL 及其束的位置，并相对于彼此和解剖标志进行定量。
描述性实验室研究。
使用射频跟踪装置对 11 个尸体膝关节的 ACL 及其束附着进行量化。
胫骨 ACL 附着中心位于外侧半月板前角后 7.5 毫米，后腘肌腱嵴前 13.0 毫米，ACL 嵴后 10.5 毫米。股骨 ACL 附着中心位于分叉嵴近端 1.7 毫米，外侧髁间嵴后 6.1 毫米。胫骨 AM 附着中心位于外侧半月板前角前内侧面后 8.3 毫米，后腘肌腱嵴前 17.8 毫米，ACL 嵴后 5.6 毫米。股骨 AM 附着中心位于分叉嵴近端 4.8 毫米，外侧髁间嵴后 7.1 毫米。胫骨 PL 束附着中心位于外侧半月板前角后内侧面后 6.6 毫米，外侧半月板后角根部附着处前内 10.8 毫米，后腘肌腱嵴前 8.4 毫米。股骨 PL 束附着中心位于分叉嵴远端 5.2 毫米，外侧髁间嵴后 3.6 毫米。
作者开发了一套全面的测量方法，包括关节镜相关的骨和软组织解剖标志，可对胫骨和股骨上的 ACL 及其各个束的附着中心进行定量。
这些与临床相关的关节镜解剖标志可以通过改善隧道位置，增强单束和双束 ACL 重建。
