A new prospective study, recently published in the American Journal of Sports Medicine, evaluates the efficacy of 3 repeated Platelet Rich Plasma (PRP) injections for chronic patellar tendinopathy (PT). The study was conducted with 28 athletes, 17 professional and 11 semi-professional, diagnosed with chronic PT that were resistant to other non-surgical treatment options. Each athlete received 3 PRP injections separated by 1 week, to the site of the tendinopathy. VISA-P, VAS, and Lysholm scores were collected, as well as 1 and 3 month MRI results.
The results revealed significant improvements in VISA-P, VAS, and Lysholm scores at 2 year follow up. Also, 21 of the 28 athletes returned to their pre-symptom sporting level by 3 months after the procedure. The MRI images illustrated improved structural integrity at 3 months, as well as complete return of normal structure in 16 patients.
Seven patients did not return to their pre-symptom sporting level, and 6 of those were considered treatment failures, with 3 people returning to sport at a lesser degree and 3 patients that required surgical intervention. This study suggests that 3 repeated PRP injections for athletes with chronic PT can potentially yield improvements in pain and function, as well as improved healing and faster return to sport. Although more trials are needed to completely validate Platelet Rich Plasma’s use in treating chronic PT, this study adds to a growing volume of research in the area.
