The anatomy of the fibular collateral ligament-biceps femoris bursa is described. The bursa is located lateral to the distal quarter of the fibular collateral ligament and forms an inverted "J" shape around the anterior and anteromedial portions of the ligament. Its most distal margin is just proximal to the fibular head where the fibular collateral ligament inserts, and its more proximal aspect is at the superior edge of the anterior arm of the long head of the biceps femoris muscle. We found this structure in all 50 knees dissected; there was a constant anatomic location of the fibular collateral ligament-biceps femoris bursa in all specimens. Measurement of the anatomic dimensions of the bursa revealed a mean width of 8.4 mm and a mean height of 18 mm. Knowing the prevalence, shape, size, and anatomic location of this bursa may aid the clinician in the differential diagnosis of lateral knee pain.
描述了腓侧副韧带-股二头肌滑囊的解剖结构。该滑囊位于腓侧副韧带远侧四分之一的外侧，围绕韧带的前部和前内侧部分形成一个倒“J”形。其最远端边缘恰在腓侧副韧带附着的腓骨头近端，其更近端部分位于股二头肌长头前臂的上缘。我们在解剖的所有50个膝关节中均发现了这种结构；在所有标本中，腓侧副韧带-股二头肌滑囊的解剖位置恒定。对滑囊的解剖尺寸测量显示，平均宽度为8.4毫米，平均高度为18毫米。了解该滑囊的发生率、形状、大小和解剖位置可能有助于临床医生对膝关节外侧疼痛进行鉴别诊断。
