To compare the effectiveness of injections of platelet-rich plasma (PRP) compared with focused extracorporeal shock-wave therapy (ESWT) among athletes with chronic patellar tendinopathy (jumper's knee). ⋯ Athletes with chronic patellar tendinopathy responded positively to both PRP injection and ESWT. However, the PRP-treated patients demonstrated significantly greater improvements in VISA-P and pain scores by 6 months and significantly better functional outcomes and satisfaction based on a modified Blazina scale, at 12 months.
