Description
Summary:	This study investigated the boundary of anserine bursa with the recommended injection site and shape on the insertion area of pes anserinus (PA), with the aim of improving clinical practice. Eighty six legs from 45 Korean cadavers were investigated. The mixed gelatin solution was injected to identify the shape of anserine bursa, and then the insertion site of the PA tendons was exposed completely and carefully dissected to identify the shape of the PA. The sartorius was inserted into the superficial layer and gracilis, and the semitendinosus was inserted into the deep layer on the medial surface of the tibia. The number of the semitendinosus tendons at the insertion site varied: 1 in 66% of specimens, 2 in 31%, and 3 in 3%. The gracilis and semitendinosus tendons were connected to the deep fascia of leg. Overall, the shape of the anserine bursa was irregularly circular. Most of the anserine bursa specimens reached the proximal line of the tibia, and some of the specimens reached above the proximal line of the tibia. In the medial view of the tibia, the anserine bursa was located posteriorly and superiorly from the tibia's midline, and it followed the lines of the sartorius muscle. The injection site for anserine bursa should be carried out at 20° from the vertical line medially and inferiorly, 15 or 20 mm deeply, and at the point of about 20 mm medial and 12 mm superior from inferomedial point of tibial tuberosity.
