Thirty-Day Unplanned Readmission after Total Knee Arthroplasty at a Teaching Community Hospital: Rates, Reasons, and Risk Factors

This study identified 7,482 primary TKA procedures of which 210 (2.8%) were unplanned readmissions. Gastrointestinal bleed (9.05%) and periprosthetic infection (8.10%) were the most common causes of readmission. Age 65 and older (odds ratio [OR], 1.64; 95% confidence interval [CI], 1.21–2.21; p = 0.0012), male (OR, 1.37; 95% CI, 1.03–1.83; p = 0.0302), length of stay > 3 days (OR, 2.04; 95% CI, 1.45–2.86; p < 0.0001), and discharge to rehab (OR, 2.21; 95% CI, 1.49–3.26; p ≤ 0.0001) were correlated significantly with risk of 30-day readmission. Chronic airway disease (OR, 2.81; 95% CI, 1.54–5.14; p = 0.0008) and obesity (OR, 1.45; 95% CI, 1.006–2.10; p = 0.0463) were significant risk factors. Higher Charlson comorbidity index was not a predictor of time to readmission within 30 days after TKA.
