Abstract

Background: Total knee arthroplasty (TKA) on an outpatient basis is controversial due to concerns about patient safety. In France, only 1.1% of TKAs performed in 2017 were outpatient procedures. Nevertheless, recent advances in the multi-modal and multidisciplinary management of TKA patients combined with optimisation of the various components of perioperative care are increasing the use of outpatient TKA. However, studies on outcomes remain scarce. The primary objective of this work was to compare readmission rates within 30 days after TKA between patients managed as outpatients and as inpatients. The secondary objectives were to compare complication rates and patient satisfaction between the two groups. Hypothesis: After outpatient TKA, the day-30 rates of readmission and complications are similar to those seen after inpatient TKA. Material and methods: A retrospective single-centre study of consecutive patients who underwent TKA between April 2014 and July 2017 was performed. Readmissions, complications, and patient satisfaction were collected. Results: Of 574 patients, 61 were selected to undergo outpatient TKA and 513 had inpatient TKA. The day-30 readmission rate was 2/61 (3.3%) in the outpatient group and 25/513 (4.9%) in the inpatient group. The overall complication rate was 8% in the outpatients and 7.2% in the inpatients. The satisfaction rate was high in the outpatient group, with 80% very satisfied and 20% satisfied patients. Conclusion: When performed in appropriately selected patients, outpatient TKA is not associated with a higher readmission rate compared to inpatient TKA. Level of evidence: IV, retrospective comparative study.
