Aim: We investigated the relationship between obstructive sleep apnea (OSA), 30/90-day readmission rates and perioperative complications (postoperative cardiovascular, gastrointestinal, infectious or intraoperative complications) in patients undergoing total knee arthroplasty. Materials & methods: We analyzed records of patients who underwent total knee arthroplasty using State Inpatient Databases. Demographics, comorbidities, 30/90-day readmission rates and complications were compared by OSA status. For NY, USA we analyzed outcomes by anesthetic type (regional vs general). Results: OSA patients were mostly male, had more comorbidities and had increased 30/90-day readmission rates. There were no differences in complications. In NY, there were no differences in outcomes by anesthetic type. Conclusion: OSA was associated with increased 30/90-day readmission rates. Within NY, anesthetic type was not associated with any outcomes.

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.
