Rapid Discharge to Home After Total Knee Arthroplasty Is Safe in Eligible Medicare Patients.

Background: This study was aimed at assessing the risk of readmission for Medicare patients discharged home within a day of total knee arthroplasty (TKA) compared to those discharged on day 2 or beyond in a community medical center.

Methods: A hospital inpatient database was queried for all unilateral, primary TKAs performed on patients 65 years or older from January 1, 2013, to December 31, 2015. A total of 2287 patients met the study criteria, of which 1502 were discharged within a day (short stay), and 785 were discharged on day 2 or beyond (traditional stay).

The AAHKS Clinical Research Award: Liposomal Bupivacaine and Periarticular Injection Are Not Superior to Single-Shot Intra-articular Injection for Pain Control in Total Knee Arthroplasty.

Background: Intraoperative injections can help reduce early postoperative pain in total knee arthroplasty. We proposed that liposomal bupivacaine would not be superior to more common and cheaper injections.

Methods: A single-blinded prospective randomized study with 207 consecutive patients was completed.
