Working model of tendinopathy. The underlying histopathology and chemical environment suggest an ongoing attempt to repair the tendon, with involvement of neurovascular ingrowth and local delivery of neuropeptides such as Substance P. Successful therapies may exploit the ability of neuropeptides to further increase blood flow to the tissue, thereby promoting the resolution of healing and regression of excessive neurovascular elements.
