We queried an institutional database to select all TKAs conducted from January 2010 to May 2020. There were 2,514 TKA pre-2014 and 5,545 TKA post-2014 that were identified. The 90-day emergency department (ED) visits, readmissions, and returns-to-operating room (OR) outcomes were identified. Patients were propensity score weight-matched as per comorbidities, age, initial surgical consultation (consult) BMI, and sex. We conducted 3 outcome comparisons: (1) pre-2014 patients who had a consult and surgical BMI ≥ 40 against post-2014 patients who had a consult BMI ≥ 40 and surgical BMI < 40; (2) pre-2014 patients against post-2014 patients who had a consult and surgical BMI < 40; (3) post-2014 patients who had a consult BMI ≥ 40 and surgical BMI < 40 against post-2014 patients who had a consult BMI ≥ 40 and surgical BMI ≥ 40.
Pre-2014 patients who had a consult and surgical BMI ≥ 40 had more ED visits (12.5% versus 6%, P = .002) but similar readmissions and returns-to-OR than post-2014 patients who had a consult BMI ≥ 40 and surgical BMI < 40. Pre-2014 patients who had a consult and surgical BMI < 40 had more readmissions (8.8% versus 6%, P < .0001) but similar ED visits and returns-to-OR when compared to their post-2014 counterparts. Post-2014 patients who had a consult BMI ≥ 40 and surgical BMI < 40 had fewer ED visits (5.8% versus 10.6%) but similar readmissions and returns-to-OR than patients who had a consult BMI ≥ 40 and surgical BMI ≥ 40.
Patient optimization prior to total joint arthroplasty is essential. Enacting BMI reduction pathways prior to total knee arthroplasty seems to afford morbidly obese patients major risk mitigation. We must continue to ethically balance the pathology, expected improvement after surgery, and the overall risks of complications for each patient.

方法:我们查询了一个机构数据库,以选择2010年1月至2020年5月进行的所有TKA。
结果:在2014年之前,有咨询且手术BMI≥40的患者有更多的ED就诊(12.5对6%,
结论:在进行全关节置换术前对患者进行优化是至关重要的。
