Myotendinous gastrocnemius tear
WebThe gastrocnemius muscle is prone to rupture because it traverses two joints and second because of the presence of a high density of fast twitch muscle fibres. The medial head is injured most often, however a haematoma between the medial gastrocnemius and soleus muscles without muscle rupture can occur. 4 WebThe majority of strains are seen at the interface between muscle fibers and tendon: the myotendinous junction (MTJ). It has a unique morphology with a highly folded muscle membrane filled with invaginations of collagen fibrils from the tendon, establishing an increased area of force transmission between muscle and tendon.
