Nontuberculous mycobacterium (NTM) is an infrequent cause of prosthetic knee joint infections. Simultaneous infection with different NTM species in a prosthetic knee joint has not been previously reported. A case of prosthetic knee joint infection caused by Mycobacterium abscessus and M. fortuitum is described in this report. The patient was successfully treated with adequate antibiotics and surgery. The clinical features of sixteen previously reported cases of prosthetic knee joint infection caused by NTM are reviewed.
非结核分枝杆菌（NTM）是人工膝关节感染的罕见病因。此前尚未有关于人工膝关节同时感染不同NTM菌种的报道。本报告描述了一例由脓肿分枝杆菌和偶然分枝杆菌引起的人工膝关节感染病例。该患者通过充分的抗生素治疗和手术得以成功治愈。本文还回顾了此前报道的16例由NTM引起的人工膝关节感染病例的临床特征。
