The vascular supply of the equine stifle joint was investigated, using latex vascular injections of pelvic limbs from 3 adult horses and 6 ponies. Vessels were grossly dissected to the small arteriole level. The primary source of blood supply was the femoral artery and its branches which entered the joint on the caudal and medial surfaces. The superficial vasculature arose from the caudal branch of the deep circumflex iliac artery cranially and laterally, and from the saphenous and descending genicular arteries medially. The deep vasculature arose from the popliteal artery and its branches on the caudal joint surface. These 2 layers of vessels arborized to form the vascular rete which surrounded the joint and gave off branches to supply the articular capsule and the intraarticular structures. Venous drainage paralleled arterial pathways.
利用对3匹成年马和6匹小马的骨盆肢进行乳胶血管注射，研究了马膝关节的血管供应。将血管大体解剖至小动脉水平。血液供应的主要来源是股动脉及其分支，它们从尾侧和内侧进入关节。浅部血管系统在头侧和外侧起源于旋髂深动脉的尾侧分支，在内侧起源于隐动脉和膝降动脉。深部血管系统起源于腘动脉及其在关节尾侧表面的分支。这两层血管分支形成血管网，围绕关节并发出分支供应关节囊和关节内结构。静脉引流与动脉走行平行。
