“…This was justified as the gradient in the ACL strain and thus its length change is reported highest in this range of flexion angles (Beynnon et al, 1992). Also the slack-taut transition of the PCL is reported to occur in this region of flexion angles as well (Makris et al, 2000) (Fig. 1).…”

“…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]. Probably because of the relatively small size of PMB on the PCL section, a small portion of fiber bundles are slacked or damaged due to strain concentration.…”

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.

“…The PCL can be divided into two bundles based on the anatomic direction of the fibres and tensioning patterns and their function: a larger anterolateral and a smaller PMBs named according to their femoral attachment 2 15 16. Additional structures can be present in this complex, and are the anterior (ligament of Humphrey) and/or the posterior (ligament of Wrisberg) meniscofemoral ligaments 14 17.…”
