Postoperative outcomes and anesthesia type in total knee arthroplasty in patients with obstructive sleep apnea: Supplementary tables 1 & 2

Plain language summary: By analyzing records of patients who underwent total knee replacement, we investigated the relationship between obstructive sleep apnea (OSA), rates of readmission to the hospital at 30 and 90 days after surgery and perioperative complications (postoperative cardiovascular, gastrointestinal, infectious or intraoperative complication). In the NY, USA population, we analyzed outcomes based on anesthetic type (regional vs general anesthesia). We found that OSA patients were mostly male, had more medical conditions and had increased rates of 30 and 90-day readmission. There were no differences in complications. In NY, there were no differences in outcomes by anesthetic type. In conclusion, OSA was associated with increased rates of readmission to the hospital at 30 and 90 days after surgery. Within NYS, anesthetic type was not associated with any outcomes.
