This study characterized a cohort of obese total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients (1/1/2008-12/31/2010) and evaluated whether a clinically significant amount of pre-operative weight loss (5% decrease in body weight) is associated with a decreased risk of surgical site infections (SSI) and readmissions post-surgery. 10,718 TKAs and 4066 THAs were identified. During the one year pre-TKA 7.6% of patients gained weight, 12.4% lost weight, and 79.9% remained the same. In the one year pre-THA, 6.3% of patients gained weight, 18.0% lost weight, and 75.7% remained the same. In TKAs and THAs, after adjusting for covariates, the risk of SSI and readmission was not significantly different in the patients who gained or lost weight pre-operatively compared to those who remained the same.
本研究对一组肥胖全髋关节置换术（THA）和全膝关节置换术（TKA）患者（2008年1月1日至2010年12月31日）进行了特征分析，并评估术前显著的体重减轻（体重下降5%）是否与手术部位感染（SSI）风险降低及术后再入院率降低相关。共识别出10718例TKA患者和4066例THA患者。在TKA术前一年，7.6%的患者体重增加，12.4%的患者体重减轻，79.9%的患者体重保持不变。在THA术前一年，6.3%的患者体重增加，18.0%的患者体重减轻，75.7%的患者体重保持不变。在TKA和THA患者中，在调整协变量后，术前体重增加或减轻的患者与体重保持不变的患者相比，SSI和再入院风险无显著差异。
