To evaluate the frequency of communication between the lateral and medial femorotibial joints and the femoropatellar joint in cattle.
1 of 3 injection sites was randomly assigned to each ox.
102 limbs were obtained from 55 fresh bovine cadavers presented for necropsy with problems unrelated to the stifle.
The joints were injected with a mixture of latex and barium sulfate. Communication between 2 or more joints was determined by the presence of latex and contrast material in a joint adjacent to the injected joint by examining frozen sections and positive-contrast arthrography.
Communication between the 3 joints was present in 58 (56.9%) limbs. The femoropatellar and the medial femorotibial joints always communicated. Thirteen of 38 (34.2%) specimens injected in the lateral femorotibial joint did not communicate with the 2 other joints. The femoropatellar joint communicated with the lateral and medial femorotibial joints on the distal abaxial aspect of the trochlear ridge.
Individual anatomic variation of the stifle in cattle should be considered when diagnostic or treatment protocols are established.
The lateral femorotibial joint should be treated separately because it does not consistently communicate with the femoropatellar or medial femorotibial joint.
评估牛股胫外侧关节与内侧关节以及股髌关节之间的连通频率。
为每头牛随机分配3个注射部位中的1个。
从55具因与膝关节无关的问题而进行尸检的新鲜牛尸体上获取了102条肢体。
向关节内注射乳胶和硫酸钡的混合物。通过检查冰冻切片和阳性对比关节造影，根据注射关节相邻关节中乳胶和造影剂的存在情况来确定两个或更多关节之间的连通情况。
58条（56.9%）肢体的3个关节之间存在连通。股髌关节和股胫内侧关节始终连通。在股胫外侧关节注射的38个标本中有13个（34.2%）与其他两个关节不连通。股髌关节在滑车嵴远端轴外侧面与股胫外侧关节和内侧关节连通。
制定诊断或治疗方案时应考虑牛膝关节的个体解剖变异。
股胫外侧关节应单独治疗，因为它与股髌关节或股胫内侧关节并非始终连通。
