<正> The arterial supply of the genicular meniscus was studied with macro-microanatomical and histological examinations

translucent preparations and scanning electronmicroscopy.It was found that the menisci were supplied by the articular branches of thepopliteal artery except the lateral superior genicular branch and the descending genicularartery.Among them there were two genicular branches with independent stems from thepopliteal artery

named as the posterior medial and posterior lateral genicular artery

whichsupplied the posterior part of the corresponding meniscus.The genicular branchesanastomosed with each other to form a vascular circle around the menisci

and minutebranches from the circle formed an arterial network around the menisci and terminated incapillaries in 3 types of anastomotic forms.The surgical approach to the menisci and theprognosis of an injured meniscus were discussed on the basis of the arterial distributionsinside and outside of the menisci.
