corrigendum anatomical characteristics and biomechanical properties of the oblique Popliteal Ligament
Scientific Reports, 2017Co-Authors: Tao Zou, Robert F Laprade, Wei Wang, Wei Huang, Shanquan SunAbstract:Scientific Reports 7: Article number: 42698; published online: 16 February 2017; updated: 10 April 2017 This Article contains an error in the Discussion section. “Even so, there remains an area without external support between the OPL, the expansion over the popliteus muscle, and the lateral side ofthe posterior cruciate Ligament, which are strongly related to the formation of Popliteal cysts”.

anatomical characteristics and biomechanical properties of the oblique Popliteal Ligament
Scientific Reports, 2017Co-Authors: Tao Zou, Robert F Laprade, Wei Wang, Wei Huang, Shanquan SunAbstract:This anatomical study sought to investigate the morphological characteristics and biomechanical properties of the oblique Popliteal Ligament (OPL). Embalmed cadaveric knees were used for the study. The OPL and its surrounding structures were dissected; its morphology was carefully observed, analyzed and measured; its biomechanical properties were investigated. The origins and insertions of the OPL were relatively similar, but its overall shape was variable. The OPL had two origins: one originated from the posterior surface of the posteromedial tibia condyle, merged with fibers from the semimembranosus tendon, the other originated from the posteromedial part of the capsule. The two origins converged and coursed superolaterally, then attached to the fabella or to the tendon of the lateral head of the gastrocnemius and blended with the posterolateral joint capsule. The OPL was classified into Band-shaped, Y-shaped, Z-shaped, Trident-shaped, and Complex-shaped configurations. The mean length, width, and thickness of the OPL were 39.54, 22.59, and 1.44 mm, respectively. When an external rotation torque (18 N·m) was applied both before and after the OPL was sectioned, external rotation increased by 8.4° (P = 0.0043) on average. The OPL was found to have a significant role in preventing excessive external rotation and hyperextension of the knee.

the role of the oblique Popliteal Ligament and other structures in preventing knee hyperextension
American Journal of Sports Medicine, 2010Co-Authors: Patrick M Morgan, Robert F Laprade, Fred A Wentorf, Jeremy W Cook, Aaron BiancoAbstract:BackgroundLigament restraints to terminal knee extension are poorly understood.Hypotheses(1) As with other motions of the knee, genu recurvatum is limited primarily by a named, identifiable structure. (2) As the largest static structure of the posterior knee, the oblique Popliteal Ligament is uniquely suited to act as a checkrein to knee hyperextension.Study DesignDescriptive laboratory study.MethodsTwenty fresh-frozen human knees were divided into 3 groups for a Ligament sectioning study. Extension moments of 14 and 27 N·m were applied before and after sectioning of each Ligament, and motion changes were recorded. In group 1, the oblique Popliteal Ligament was sectioned first, followed by the fabellofibular Ligament, Ligament of Wrisberg, anterior cruciate Ligament, posterolateral structures, and posterior cruciate Ligament. In group 2, the order was altered to section the anterior cruciate Ligament first; no other changes were made. Similarly, the cutting order for group 3 was altered to section the pos...
