“…27 However, a more recent systematic review by Narvy et al 15 clarified the precise femoral attachments of the anterolateral and posteromedial bundles based on both cadaveric and radiographic data. 15 By defining the precise femoral insertion point of the PCL ALB, we were able to use virtual femoral sockets to determine drill guide reference angles that would ensure an ideal femoral socket.…”

“…Narvy et al, 15 in their systematic review, investigated the femoral insertion of the PCL. Based on the reviewed cadaveric data, the center of the ALB was found to be 8 mm from the anterior surface of the femur, 4.7 mm tangent from Blumensaat's line toward the intercondylar notch, and 3.6 mm from the medial intercondylar ridge.…”

Isolated posterior cruciate ligament (PCL) tears are much less frequent than anterior cruciate ligament (ACL) tears.Abrupt posterior tibial translation (such as dashboard impact), falls in hyperflexion and direct hyperextension trauma are the most frequent mechanisms of production.The anterolateral bundle represents two-thirds of PCL mass and is reconstructed in single-bundle techniques.The PCL has an intrinsic capability for healing. This is the reason why, nowadays, the majority of isolated PCL tears are managed non-operatively, with rehabilitation and bracing.Recent studies have focused on double-bundle reconstruction techniques, as they seem to restore knee kinematics.No significant clinical differences have been established between single versus double-bundle techniques, autograft versus allograft, transtibial tunnel versus tibial inlay techniques or remnant-preserving versus remnant-release techniques.Cite this article: EFORT Open Rev 2017;2:89-96.

“…Under a relatively larger load (600, 800, and 1000 N), PMB could still retain a certain tensity at all the positions. The cross-sectional area of ALB is twice as large as that of PMB [21]. Some scholars even supposed that the posterior fibers only took up 15% of the whole PCL volume [22].…”

BackgroundThe objective of this study was to investigate the biomechanical and histological effects of the posterior cruciate ligament (PCL) on the medial tibial plateau.MethodsA total of 12 cadaveric human knee specimens were collected and grouped as follows: the PCL intact group (n = 12), the anterolateral bundle rupture group (n = 6), the postmedial bundle rupture group (n = 6), and the PCL rupture group (n = 12). The strain on the anterior, middle, and posterior parts of the medial tibial plateau with an axial loading force at different flexion angles was measured and analyzed, respectively. Forty-eight rabbits were chosen for animal study: surgery was performed on the one side of each rabbit randomly (experimental group), while the other side was taken as control (control group). Every 12 rabbits were culled at each of the four selected time points to collect the medial tibial plateau for morphological and histological observation.ResultsThe PCL rupture, either partial or complete, may generate an abnormal load on all the parts of the medial tibial plateau with axial loading at all positions. Noticeable time-dependent degenerative histological changes of the medial tibial plateau were observed in the rabbit models of PCL rupture. Compared with the control group, all the PCL rupture groups exhibited a higher expression of the matrix metalloproteinase-7 (MMP-7) and the tissue inhibitors of metalloproteinase-1 (TIMP-1) at all the time points.ConclusionsEither partial or complete PCL rupture may generate an abnormal load on all the parts of the medial tibial plateau with axial loading at all the positions and may cause cartilage degeneration on the medial tibial plateau.
