Bilateral total knee arthroplasty (TKA) can be performed under a single-anesthetic (SA) or staged under a two-anesthetic (TA) technique. Recently, our institution began piloting a two-surgeon team SA method for bilateral TKA. The purpose of this study was to compare the inpatient costs and clinical outcomes in the first 90 days after surgery between the team SA, single-surgeon SA, and single-surgeon TA approaches for bilateral TKA. All primary TKA performed from 2007–2017 by the two participating surgeons for each of the 3 groups of interest were identified: team SA (N=42 patients; 84 knees), single-surgeon SA (N=146 patients; 292 knees), single-surgeon TA (N=242 patients; 484 knees). No patients were lost to follow-up.Introduction
