Refractory patellar tendinopathy (RPT) is a chronic disease with progressive degeneration of extracellular matrix, microtearing, and loss of tendon microarchitecture as a hallmark. The essential pathologic lesion of tendinopaty is often described as a failed healing response of the tendon, and persistence of the lesion is attributed to the tissue anchored in the proliferative or angiogenic phase, as shown in histopathology .
Structural findings of collagen degeneration and angiofibroblastic neoplasia have been well described and are now referred to as "neovascular tendinosis." The presence of neovascularization has been theorized to cause pain in patients with tendinopathy .
Recent studies have examined the role of neo-vessels and neoinnervation on chronic tendon pain and dysfunction, and interventions targeting this process have reported favorable outcomes in RPT (Figure 1) .

Ultrasound-guided Intratissue percutaneous electrolysis (EPI®) treatment is the application of a direct current (DC) whose catodic flow is transferred to the area of the degenerative tendon using an acupuncture needle .
This accumulated electrical charge (AEC) in the degenerative tissue will produce the activation of the molecular, celular and biological processes necessary to restore the regeneration mechanisms of the tendon. In recent studies it has been demonstrated that EPI® technique is effective in tendinopathy and sport muscular injuries (Figures 2-4) [5-7].
