Rupture of the patellar tendon
is becoming more and more frequent, even in sports activities overloading the extensor mechanism of the knee. 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.
A 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. This case questions the actual efficacy and safety of PRP in severe degenerative tendinopathies.
