The aim of the study is the evaluation of clinical and radiological results after the treatment of patellar tendinopathy through the injection of autologous ultrasound-guided, intra- and peri-tendon stromal vascular fraction.
After being informed about the study and potential risks, all patients giving written informed consent will be treated according to the study protocol. Every patients will undergo to a single peri- and intra- tendon injection with Autologous Stromal Vascula Fraction (SVF). At baseline and at every follow-ups patients will be evaluated clinically and radiologically. In particular, clinical evaluation and questionnaires will be performed at baseline, 1, 3, 6, 12 and 24 months visits, Ultrasound will be performed at baseline, 6 and 12 months visits. MRI will be performed at baseline and 6 months visits.
