Comparative Study
Comparing the Safety and Outcome of Simultaneous and Staged Bilateral Total Knee Arthroplasty in Contemporary Practice: A Systematic Review of the Literature.
Although a variety of studies have assessed the outcomes of simultaneous bilateral total knee arthroplasty (BTKA) and staged BTKA, there remains no definitive conclusion regarding the superiority of one technique in terms of safety. ⋯ In contemporary studies involving comparable baseline demographics (including comorbidity index, American Society of Anesthesiologists grade), there was moderate evidence to show that simultaneous BTKA is as safe as the staged BTKA.

Alternative payment models such the Centers for Medicare and Medicaid Services Bundled Payments for Care Improvement (BPCI) initiative have been effective in reducing costs following unilateral total hip (THA) and knee arthroplasty (TKA), but few studies exist on bilateral arthroplasty. This study aimed to determine whether the BPCI program for bilateral THA and TKA reduced episode-of-care costs. ⋯ Our bundled payment program for bilateral THA and TKA was successful with reduction in 90-day episode-of-care costs without placing the patient at higher risk of readmission. Older Medicare beneficiaries and those with cardiac disease should likely not undergo a simultaneous bilateral procedure due to concerns about increased costs.

The Outpatient Arthroplasty Risk Assessment (OARA) score was designed to identify patients medically appropriate for same- and next-day discharge after surgery. The purpose of this study was to update and confirm the greater predictive utility of the OARA score in relation to American Society of Anesthesiologists Physical Status (ASA-PS) classification for same-day discharge and to identify the optimal preoperative OARA score for safe patient selection for outpatient surgery. ⋯ The OARA score was designed to err in the direction of medical safety, and OARA scores between 0 and 79 are conservatively highly effective for identifying patients who can safely elect to undergo outpatient total joint arthroplasty. The ASA-PS classification does not provide sufficient discrimination for safely selecting patients for outpatient arthroplasty.

The purpose of this study is to evaluate the 5-factor modified frailty index (mFI-5) as a predictor of postoperative complications, readmission, and mortality in patients undergoing revision hip and knee arthroplasty. ⋯ III.

The use of tranexamic acid (TXA) has been proved to be effective in reducing blood loss and transfusion requirements after primary total knee arthroplasty (TKA). However, the evidence for its use in revision surgery is scant. We assessed the safety and efficacy of topical TXA in revision TKA. ⋯ Topical TXA in revision TKA is safe and effective in reducing blood loss and transfusions. This effect is enhanced when both components are revised. Additionally, the use of TXA may improve early outcomes.
