Abstract: Background As already well known, patellar tendinopathy symptoms are recovered after the injections of platelet- rich plasma (PRP), still to date, rarely few studies have worked on comparison of PRP with dry needling (DN) for this condition. Purpose To compare the efficacy of eccentric exercises integrated with either ultrasound-guided leukocyte-rich PRP injection (including dry needling) or ultrasound- guided dry needling alone in the treatment of patellar tendinopathy. Study Design Retrospective, nonrandomized, open label, comparative case series included 50 patients of PT visited at Era’s medical college, Lucknow, Uttarpradesh between October 2018 to October 2019. Methods As per exclusion and inclusion criteria, the patient was recruited in the study after diagnosed by clinical investigation and magnetic resonance imaging. Patients (n=50) divided into two groups and received ultrasound- guided DN alone (DN group; n = 23) or with the injection of leukocyte-rich PRP (PRP group; n = 27), along with standardized eccentric exercises. After treatment during further follow-up visits (at baseline, 12 and 26 weeks) enrolled patients were asked to complete patient-reported outcome questionnaires. Victorian Institute of Sports Assessment (VISA) scores, the visual analog scale (VAS) for pain. Tegner activity scale, Lysholm knee scale, and short form (SF-12) questionnaire were the outcome parameter that was estimated at baseline and follow up visits. Results There was a significant difference in the mean VISA score for DM group (M=4.2, SD=1.3) and PRP group at the baseline (P=<0.001) and after 12 weeks (P=0.001) and 26 weeks (P=<0.001) of treatment. Similarly, the mean Lysholm score was significantly more evident in DM group compared to the PRP group after 26 weeks (P=<0.001) of treatment. Controversy, the mean Lysholm score was significantly less evident in the DM group compared to the PRP group at baseline (P=<0.001) and after 12 weeks (P=0.001) of treatment. SF-12 score was significantly higher in DM group compared to the PRP group at baseline (P=0.015) and, in further follow-up, it was not significantly different. Conclusion Remedial of standardized eccentric exercise and ultrasound-guided leukocyte-rich PRP injection with DN group induces the improvement in symptoms of patellar tendinopathy compared to ultrasound-guided DN alone, but over time, the explicit advantage of PRP disappeared.
