EM analysis of the human hamstring musculotendinous junction (MTJ) demonstrates a classic interdigitated MTJ and a previously undescribed flat MTJ

      Introduction: There is a paucity of research on the structure and function of the musculotendinous junction (MTJ) in humans with no previous images available in the literature. It is considered that musculotendinous junctions have interdigitated and locked joins thereby increasing the surface area of the junction to allow for a better force transmission between muscle and tendon. The aim of this study was to look at the electron microscopy images of a human hamstring MTJ. The results were then compared to the known literature on this subject and subsequently to assess the implications for hamstring (muscle) injuries.
