An anomalous bifurcation of the sartorius muscle.

The sartorius muscle on one side of the body of an 60 years old man was found to be divided into 2 parts at its distal end. The lateral part was inserted into the medial condyle of the femur. The medial part was inserted as the classically described insertion of the muscle into the medial surface of the tibia. This is a significant nonrecorded variation of the muscle to both clinicians and gross anatomists.
