Patient Perceptions of the Safety of Outpatient Total Knee Arthroplasty

Abstract

Background: Outpatient total joint arthroplasty is considered safe in a selected group of patients, based primarily on complications. However, patient perception of the safety of outpatient total joint arthroplasty is unknown. This study assesses patient perceptions of the potential benefits of and barriers to outpatient total knee arthroplasty among a cohort of patients who have recently undergone the procedure.

Methods: Patients who underwent unilateral primary total knee arthroplasty between March 1, 2017, and September 30, 2017 at our institution were given a questionnaire, in which they were asked about prior knowledge regarding outpatient total knee arthroplasty, their perceived ability to undergo the procedure as an outpatient, and their perceived risks and benefits to outpatient surgery.

Results: Three hundred forty-six patients completed the survey. Over 70% of patients did not think that they would be able to undergo total knee arthroplasty as an outpatient. Their primary concerns were pain, being able to go to the bathroom, and falls.

Conclusions: Patients in this study largely would not feel safe undergoing total knee arthroplasty on an outpatient basis. Payers should not only take into account existing literature but also the concerns and perceived needs of patients, before encouraging widespread implementation of outpatient total knee arthroplasty.
