Abstract

The semitendinosus and gracilis muscles insert primarily onto the superior medial aspect of the tibia. These tendons can be harvested for anterior cruciate ligament reconstruction, and knowledge of their accessory attachments is important for the success of such harvesting procedures. Here, we present a case illustration and review of the attachment of these muscles into the crural fascia (deep fascia of the leg), which is often an underappreciated insertion site.

Note the semitendinosus and gracilis distal tendons inserting not only into their normal site but also into the crural fascia (arrows in the zoomed in view).
