Using a private insurance claims' database, we identified patients who underwent ACL reconstruction from 2010 to 2015 using the International Classification of Diseases, Version 9 (ICD-9) and Current Procedural Terminology (CPT) codes. Univariate analysis was performed on demographic data, surgical characteristics, and comorbidities. Variables with p\u2009&lt;\u20090.10 were added to a multivariate logistic regression model which was created to identify independent risk factors for all-cause readmission within 90 days postoperatively. Significance was considered at p\u2009&lt;\u20090.05. Overall, 90,263 patients were included (average age: 29\u2009\u00b1\u200913 years, 44% female), and 1,066 (1.2%) of patients had a hospital readmission within 90 days following surgery. Risk factors for hospital readmission included cerebrovascular disease (odds ratio [OR]\u2009=\u20093.4, 95% confidence interval [CI]: 1.9, 6.2), diabetes mellitus (OR\u2009=\u20092.6, 95% CI: 1.9, 3.5), concomitant medial collateral ligament (MCL) or lateral collateral ligament (LCL) reconstruction (OR\u2009=\u20092.5, 95% CI: 1.9, 3.3), concomitant posterior cruciate ligament (PCL) reconstruction (OR\u2009=\u20092.2, 95% CI: 1.4, 3.3), age between 44 and 65 years (OR\u2009=\u20092.1, 95% CI: 1.6, 2.9), and depression (OR\u2009=\u20091.88, 95% CI: 1.49, 2.38, p\u2009&lt;\u20090.001). Female sex was associated with decreased odds of 90-day hospital readmission (OR\u2009=\u20090.8, 95% CI: 0.7, 0.9). Each hospital readmission accounted for an estimated $17,841 (95% CI: $17,173, 18,509) in gross health care payments, and patients with readmissions had substantially higher 1-year cumulative health care costs. Readmission after ACL reconstruction was 1.2%. The strongest risk factors for 90-day readmission include cerebrovascular disease, diabetes mellitus, concomitant MCL\/LCL reconstruction, concomitant PCL reconstruction, and age between 44 and 65 years. Readmission was associated with substantial health care costs.<\/jats:p>","DOI":"10.1055\/s-0041-1736200","type":"journal-article","created":{"date-parts":[[2021,10,6]],"date-time":"2021-10-06T07:28:55Z","timestamp":1633505335000},"page":"459-464","source":"Crossref","is-referenced-by-count":4,"title":["Risk
