Platelet-rich plasma was more effective than extracorporeal shock wave therapy in the treatment of athletes with jumper’s knee, according to researchers from Rome.

“Therapeutic injections of [platelet-rich plasma] PRP lead to better midterm clinical results compared with focused [extracorporeal shock wave therapy] ESWT in the treatment of jumper’s knee in athletes,” Mario Vetrano, MD, and colleagues wrote in the study abstract.

The researchers randomized 46 athletes with jumper’s knee into two groups: one group received two autologous PRP injections during a 2-week period, while the other group received three sessions of ESWT, according to the abstract.

While there were no significantly differences between the two groups at 2-month follow-up, the PRP grouped had significantly improved results in Victorian Institute of Sports Assessment-Patella, VAS and modified Blazina scale scores compared to the ESWT group at 6-month and 12-month follow-up.

The researchers noted no significant difference in age, gender, preclinical treatment or sports participation between groups. Both groups improved significantly at all follow-up periods regardless of treatment method.
