“…When the deficiency is small, direct repair can be attempted; however, in most situations, the chronicity of the rupture results in a significant segment of tendon that requires excision, leaving a moderate gap that prevents primary apposition. In these cases, local tendinous flaps, [19][20][21] advancements, [22][23][24] autograft tissue, 25,26 or allograft tissue 27,28 can be used to restore continuity of the muscle tendinous unit. When these gaps are large or muscle degeneration has occurred within the gastrocnemius and soleus muscle, tendon transfers can provide a viable option for reconstruction.…”
