Evaluation of the Effectiveness of Extracorporeal Shockwave Therapy in Patients With Patellar Tendinopathy on Its Micromorphology

Low-energy focused extracorporeal shockwave therapy will be applied 4 times with an interval of 7 days from the BTL-6000 FSWT device with piezoelectric generator. The energy can vary between 0.12-0.20 mJ/mm2 based on the pain toleration, frequency 5 Hz, total number of shocks 2x2000. The application of the first set of shocks will be semi-static at the location of the largest USG defined pathology in the patellar tendon and the second set of shocks will be performed dynamically to the proximal tendon. These parameters were selected in accordance to ISMST guidelines.
