BackgroundThe hamstring tendons, gracilis and semitendinosus are widely used in ligament and reconstructive surgery. Their accessory bands or insertions are technical pitfalls during harvesting.MethodsThirty fresh cadaver knees have been studied, in order to 1) determine the anatomy of the bands of the gracilis and semitendinosus tendons, and, 2) to identify risk factors for failure during harvesting.ResultsSemitendinosus always had at least one band, sometimes two, strong, tendinous, and generally running to the fascia of gastrocnemius medialis to which they are attached, at an acute angle in a distal direction. Their presence is constant and they are only exceptionally found more than 100 mm from the tendon's tibial insertion. Gracilis shows the greatest anatomical variability, and over one quarter have no bands (although there may be as many as three). Their location, destination and angle of attachment to the tendon vary greatly. These bands are mainly aponeurotic and less strong, but must be carefully and widely dissected.ConclusionAnatomical variability makes harvesting of pes anserinus tendons difficult. Three simple anatomical criteria have been highlighted that can be assessed by the surgeon during harvesting. The criteria are the insertion, the direction and the anatomical type of the bands.
