Abstract：
A variety of intra-articular injections are used for the management of osteoarthritis. A rare complication of intra-articular injections is acute pseudoseptic arthritis, which mimics true septic arthritis. To the authors knowledge, pseudosepsis has not been reported as a complication after platelet-rich plasma (PRP) injections. We present a case report of pseudoseptic arthritis resulting in acute postinjection pain and a joint effusion after an intra-articular PRP injection into the knee. Clinically, pseudosepsis can occur after PRP treatment with significantly elevated white blood cell counts in the synovial fluid, and should be a consideration in cases of post-PRP injection flares.
摘要：
各种关节内注射用于治疗骨关节炎。关节内注射的罕见并发症是急性假性脓性关节炎，模仿真正的化脓性关节炎。就作者所知，在注射富血小板血浆（PRP）后，假性脓毒症尚未被报道为并发症。我们提供了一例假性脓性关节炎的病例报告，该病例报告在膝关节内注射PRP后导致急性注射后疼痛和关节积液。临床上,PRP治疗后可发生假性脓毒症，滑液中白细胞计数显著升高，并且在PRP后喷射耀斑的情况下应该考虑。
