本研究采用显微外科技术对膝关节伸肌结构进行了解剖学研究。使用了10个新鲜冷冻的成人尸体膝关节。测量股四头肌、髌下肌腱、髌股韧带及其与邻近解剖结构的关系。股外侧肌和股内侧肌纤维与直肌腱的夹角分别为26.6和41.1 °。连接股骨内上髁与髌骨内侧缘的内侧髌股韧带长约54.2 mm，宽度范围为9 - 30 mm。内侧髌半月板韧带与半月板的连接较宽，而与髌骨的连接较窄。髌腱与髌骨顶点连接处宽31.9 mm，与胫骨结节连接处宽27.4 mm。长38-49毫米。使用手术显微镜，我们能够解剖和识别髌骨纤维软组织的三层排列。同时，我们能够识别髌骨周围的血管和神经。详细的临床相关性和可能的病理影响的材料进行了讨论。重点放在髌股关节的稳定性和复杂的相互作用之间的一系列因素提供它。
This study investigated the anatomy of the structures that form the extensor mechanism of the knee joint using microsurgical techniques. Ten fresh-frozen human adult cadaveric knees were used. The quadriceps components, the infrapatellar tendon, the patellofemoral ligaments, and their relations to the neighboring anatomical structures were measured. The angles of the vastus lateralis and the vastus medialis muscle fibers to the rectus tendon were 26.6 and 41.1 degrees, respectively. The medial patellofemoral ligament connecting the femoral medial epicondyle to the medial edge of the patella was approximately 54.2 mm long, and its width ranged from 9 to 30 mm. The medial patellomeniscal ligament had a wide attachment to the meniscus whereas the attachment to the patella was narrow. The patellar tendon was 31.9 mm broad at its attachment to the apex of the patella and 27.4 mm wide at its attachment to the tibial tubercle. It was 38-49 mm long. Using the surgical microscope we were able to dissect and identify a trilaminar arrangement of prepatellar fibrous soft tissues. Also, we were able to identify the vessels and nerves around the patella. Details of clinical relevance and the possible pathological implications of the material presented are discussed. Emphasis is placed on the stability of the patellofemoral joint and the complex interaction between a range of factors providing it.
