EFFICACY OF AUTOLOGOUS PLATELET-RICH PLASMA IN THE MULTIMODAL TREATMENT OF PATELLAR TENDINOPATHY IN ATHLETES

Abstract

Aim. This study aims to establish an evidence-based foundation for the efficacy of autologous platelet-rich plasma (PRP) in the treatment of patellar tendinopathy among both professional and amateur athletes. Materials and methods. A retrospective analysis involved 40 professional and amateur athletes diagnosed with patellar tendinopathy, confirmed via magnetic resonance imaging (MRI). Participants were stratified into 2 groups of 20 individuals each. Group I received 2 injections of PRP administered at a 7-day interval, supplemented by standard therapeutic interventions, including physical therapy and physiotherapy. Group II received only the standard treatment protocol without PRP injections. Treatment outcomes were evaluated with the following: 1. the Single Leg Decline Squat (SLDS) test, performed on a 25-degree incline board; 2. the Victorian Institute of Sports Assessment for Patellar Tendinopathy (VISA-P) score, which quantifies the functional status of the patellar tendon. Results. The findings demonstrate that PRP injections significantly enhance therapeutic outcomes in patients with patellar tendinopathy. Both professional and amateur athletes exhibited comparable improvements when PRP was integrated into a comprehensive treatment regimen. Conclusion. Two injections of autologous platelet-rich plasma administered at a 7-day interval are recommended to optimize the treatment of patellar tendinopathy in athletes. This approach, when combined with standard protocols, represents a clinically effective strategy for managing this condition.
