Platelet-rich plasma (PRP) treatment has been recently introduced in treatment for several knee- and sport-related injuries including muscle strain cartilage defect and tendinopathies. The aim of this case report is to present a case of rupture of the patellar tendon occurred after injections of PRP.

Case ReportA case of a 40-year-old male soccer player sustaining a patellar tendon rupture after a series of 4 PRP injections. At surgery, a complete rupture in the middle of the patellar tendon was found, with severe degenerative changes of the tendon tissue.
