Abstract:
Objective To provide an anatomic evidence for the double-bundle posterior cruciate ligament (PCL) reconstruction, the sizes and locations of the attachments of the PCL to the tibia and the femur were measured. Methods We studied 30 cadaveric knees. PCLs were divided into anterolateral and posteromedial bundles to the insertion footprint, and those locations were measured and described. Results The distances from the center of the femoral insertions of the anterolateral and posteromedial bundles to the anterior margin of the medial femoral condyle were (8.52±1.81)mm and (11.63±1.81)mm. The vertical distances from the center of the femoral insertions of the double-bundle to the intercondylar roof were (4.67±0.55)mm and (10.32±1.23) mm. The vertical distances from the tibial insertion of the center of the double-bundle to the plane of the tibial articular surface were (8.43±1.21)mm and (14.52±2.31)mm. The distances from the medial margin of the articular cartilage of the tibial plateau to the center of the tibial insertions of double-bundle were (47.44±6.23)mm and (45.95±6.32)mm. The areas of the insertions of the anterolateral and posteromedial bundles on the femur were (107.12±15.25)mm~2 and (65.35±10.27)mm~2. The areas of the insertions of the double-bundle on the tibia were (50.07±11.33)mm~2and (51.08±10.22)mm~2. Conclusion The anatomic characteristic of the attachment of the anterolateral and posteromedial bundles was revealed, providing anatomical bases for surgery.
