The ACL and its individual bundle attachment centers on the tibia and femur, according to a study published in The American Journal of Sports Medicine.
Quantification of the ACL and its bundle attachments was performed on 11 cadaveric knees using a radiofrequency tracking device, and researchers found that the tibial ACL attachment center was 7.5 mm medial to the anterior horn of the lateral meniscus, 13 mm anterior to the retro-eminence ridge and 10.5 mm posterior to the ACL ridge.
The tibial PL bundle attachment center was 6.6 mm medial to 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 researchers developed a comprehensive compilation of measurements of arthroscopically pertinent bony and soft tissue landmarks that show the center of the bundle attachment on the tibia and the femur.
These landmarks could enhance the single- and double-bundle ACL reconstructions through improved tunnel placement.
