Abat, P. Gelber, F. Polidori, J. Monllau, J. Sanchez-Ibañez] Purpose: To investigate the outcome of ultrasound (US)-guided intratissue percutaneous electrolysis (EPI®) and eccentric exercise in the treatment of patellar tendinopathy during a long-term follow-up. Methods: Forty patients with patellar tendinopathy were prospectively evaluated over a 10-year follow-up period. Pain and function were evaluated before treatment, at 3months and at 2, 5 and 10years using the Victorian Institute of Sport Assessment-Patella (VISA-P) score, the Tegner score and Blazina's classification. According to VISA-P score at baseline, patients were also dichotomized into Group 1 (<50 points) and Group 2 (≥50 points). There were 21 patients in Group 1 and 19 in Group 2. Patient satisfaction was measured according to the Roles and Maudsley score. Results: The VISA-P score improved globally by 41.2 points (p<0.01) after a mean 4.1 procedures. In Group 1, VISA-P score improved from 33.1±13 to 78.9±14.4 at 3-month and to 88.8±10.1 at 10-year follow-up (p<0.001). In Group 2, VISA-P score improved from 69.3±10.5 to 84.9±9 at 3-month and to 96.0±4.3 at 10-year follow-up (p<0.001). After 10years, 91.2% of the patients had a VISA-P score >80 points. The same level (80% of patients) or the Tegner score at no more than one level lower (20% of patients) was restored, and 97.5% of the patients were satisfied with the procedure. Conclusion: Treatment with the US-guided EPI® technique and eccentric exercises in patellar tendinopathy resulted in a great improvement in knee function and a rapid return to the previous level of activity after few sessions. The procedure has proved to be safe with no recurrences on a long-term basis. Level of evidence: Therapeutic study, Level IV.
