The purpose of the study was to quantitatively examine the anatomical organization of medial femoral perforators. Mini-incision approaches to total knee arthroplasty are being used more often; however, no studies have examined the quantitative anatomy of perforating vessels into the distal intermuscular septum. Fourteen embalmed cadaveric knees were dissected to identify where vascular perforators pierced the medial intermuscular septum. Quantitative measurements were made from the perforators to the medial epicondyle of the femur. The mean measurements from the medial epicondyle to each of the vascular perforators were 7.1, 10.5, and 13.5 cm. The closest perforator to the medial epicondyle was found at a distance of 5.5 cm. During mini-incision approaches to the knee, vascular perforators are at potential risk of injury when dissection proceeds 5 cm proximal to the medial epicondyle.
本研究的目的是定量研究股内侧穿支的解剖结构。全膝关节置换术的小切口入路应用越来越多；然而，目前还没有研究探讨穿支血管进入关节内肌间隔的定量解剖结构。本研究共解剖了 14 具防腐尸体膝关节，以确定血管穿支在何处穿入关节内肌间隔。对穿支至股骨内上髁的距离进行了定量测量。从股骨内上髁到每个血管穿支的平均测量值分别为 7.1、10.5 和 13.5cm。距离股骨内上髁最近的穿支为 5.5cm。在膝关节小切口入路中，当在距离股骨内上髁近端 5cm 处进行解剖时，血管穿支有受伤的风险。
