Popliteus Muscle

Abstract Background:The popliteal muscle-tendon complex (PMTC) belongs to the deep structure of the posterolateral complex (PLC) of human knee, which plays an important role in the posterolateral stability of the knee joint. At present, the anatomical relationship between the popliteal muscle and its adjacent structures remains controversial, especially the posterior cruciate ligament (PCL) and popliteal muscle. The revealation of anatomical connection between the popliteus muscle and its deep structures could provide an anatomical basis for the reconstruction of the PLC injury.Methods: To observe and analyze the relationship between popliteal muscle and the PCL, posterior meniscofemoral ligament (PMFL), lateral meniscus and articular capsule (AC). The dissection of 7 cases of adult human knee joint fixed with formalin, and 9 cases of sagittal P45 plastinated section of the knee joint were involved in this study. Results: For the popliteal muscle, the anatomical dissection showed that at the posterior edge of the platform of the lateral condyle of the tibia, at the tendon-muscle transition, from medial to lateral, separately sent out: dense connective tissue to connect with the PCL, dense fiber bundles to connect with the PMFL, and dense connective tissue band to connect the lateral meniscus. Meanwhile, the results of the P45 section revealed that the popliteal muscle fascia ran superiorly over the posterior edge of the tibialintercondylar eminence, andturned forward to be integrated into the PCL. Laterally, near the posterior edge of the lateral tibial plateau, the popliteal tendon penetrates through the articular capsule, where two dense fiberous bundleswere given off upwards by the popliteal tendon: one was the ventral fiber bundle,which ran superiorly over the posterior edge of the tibial plateau and then moved forwards to connect with the lateral meniscus; the dorsal fibersbundle ascended directly and participated in the AC.Conclusion: Popliteus muscle was connected with PCL, AC, lateral meniscus, and PMFL via the dense connective tissues near its tendon-muscle transition.

Popliteus Muscle

To investigate the effect of simulated contraction of the popliteus muscle on the in situ forces in the posterior cruciate ligament and on changes in knee kinematics, we studied 10 human cadaveric knees (donor age, 58 to 89 years) using a robotic manipulator/universal force moment sensor system. Under a 110-N posterior tibial load (simulated posterior drawer test), the kinematics of the intact knee and the in situ forces in the ligament were determined. The test was repeated with the addition of a 44-N load to the popliteus muscle. The posterior cruciate ligament was then sectioned and the knee was subjected to the same tests. The additional popliteus muscle load significantly reduced the in situ forces in the ligament by 9% to 36% at 90° and 30° of flexion, respectively. No significant effects on posterior tibial translation of the intact knee were found. However, in the ligament-deficient knee, posterior tibial translation was reduced by up to 36% of the translation caused by ligament transection. A coupled internal tibial rotation of 2° to 4° at 60° to 90° of knee flexion was observed in both the intact and ligament-deficient knees when the popliteus muscle load was added. Our results indicate that the popliteus muscle shares the function of the posterior cruciate ligament in resisting posterior tibial loads and can contribute to knee stability when the ligament is absent.
