A 25-year-old female presented with left knee pain following arthroscopic synovectomy for presumed pigmented villonodular synovitis (PVNS). Radiographs and magnetic resonance imaging demonstrated tricompartmental arthritic changes. She underwent a two-stage procedure first involving antibiotic spacer implantation, followed 1 week later by spacer removal and definitive total knee arthroplasty (TKA) once initial intraoperative culture results were negative. Subsequent cultures confirmed tuberculosis septic arthritis. Repeat evaluation 1 year postoperatively showed no complications and patient satisfaction with left knee function. This is a unique case report in the United States describing 1-year outcomes following staged TKA for tuberculosis septic arthritis masquerading as PVNS.
一位 25 岁女性在接受关节镜下滑膜切除术治疗疑似色素沉着绒毛结节性滑膜炎（PVNS）后出现左膝疼痛。X 线片和磁共振成像显示三腔关节炎性改变。她接受了两阶段手术，首先是抗生素间隔物植入，1 周后间隔物取出，一旦初始术中培养结果为阴性，就进行确定性全膝关节置换术（TKA）。随后的培养结果证实为结核性化脓性关节炎。术后 1 年的重复评估显示无并发症，患者对左膝功能满意。这是美国首例分期 TKA 治疗伪装成 PVNS 的结核性化脓性关节炎的 1 年随访结果的独特病例报告。
