Introduction: Classically the adductor canal is made from the fascial contributions from sartorius, adductor longus, adductor magnus and vastus medialis muscles. The contents of the adductor canal include femoral artery, femoral vein, and saphenous nerve. While the femoral artery and vein continue posteriorly through the adductor hiatus, the saphenous nerve travels all the way through the adductor canal and exits the inferior opening of the adductor canal.
Methods: During routine dissection, one specimen was found to have an abnormal tendinous contribution to the adductor canal.
Results: This tendon arose from the distal portions of adductor longus and created part of the roof of the canal.
Conclusions: The clinical consequences of such an anomaly may include conditions such as saphenous neuritis, adductor canal compression syndrome, as well as paresthesias along the saphenous nerve distribution.
