Periprosthetic joint infection (PJI) represents substantial clinical and economic burdens. This study evaluated patient and procedure characteristics and resource utilization associated with revision arthroplasty for PJI. The Nationwide Inpatient Sample (Q4 2005-2010) was analyzed for 235,857 revision THA (RTHA) and 301,718 revision TKA (RTKA) procedures. PJI was the most common indication for RTKA, and the third most common reason for RTHA. PJI was most commonly associated with major severity of illness (SOI) in RTHA, and with moderate SOI in RTKA. RTHA and RTKA for PJI had the longest length of stay. Costs were higher for RTHA/RTKA for PJI than for any other diagnosis except periprosthetic fracture. Epidemiologic differences exist in the rank, severity and populations for RTHA and RTKA for PJI.
人工关节周围感染（PJI）带来了巨大的临床和经济负担。本研究评估了与PJI翻修关节成形术相关的患者和手术特征以及资源利用情况。对2005年第4季度至2010年的全国住院患者样本进行分析，涉及235,857例翻修全髋关节置换术（RTHA）和301,718例翻修全膝关节置换术（RTKA）。PJI是RTKA最常见的适应证，也是RTHA第三常见的原因。在RTHA中，PJI最常与严重疾病严重程度（SOI）相关，而在RTKA中则与中度SOI相关。因PJI进行的RTHA和RTKA住院时间最长。除人工关节周围骨折外，因PJI进行RTHA/RTKA的费用高于任何其他诊断。因PJI进行RTHA和RTKA在排名、严重程度和人群方面存在流行病学差异。
