Short-term Risk of Revision THA in the Medicare Population Has Not Improved With Time

Abstract

Introduction Advances in surgical technique, implant design, and clinical care pathways have resulted in higher expectations for improved clinical outcomes after primary THA; however, despite these advances, it is unclear whether the risk of revision THA actually has decreased with time. Understanding trends in short-and mid-term risks of revision will be helpful in directing clinical, research, and policy efforts to improve THA outcomes.Question/purposes We therefore asked (1) whether there have been changes in overall short-and mid-term risks of revision THA among patients in the Medicare population who underwent primary THA between 1998 and 2010; and (2) whether there are different demographic factors associated with short-and mid-term risks of revision THA. Methods Using the Medicare 5% national sample database, patients who underwent primary THA between 1998 and 2010 followed by subsequent revision through 2011

Cost‐effectiveness of a novel, fluoroscopy‐based robotic‐assisted total hip arthroplasty system: A Markov analysis

“…Transition probabilities are defined as the likelihood that a patient will enter a specific health state per cycle, and were computed Infection 0.1 i 1.7 2,25,26 Dislocation 0.1 i 0.6 2,24 No complication revision 0.1 i 0.6 2,30 Aseptic revision 6.1 31 6.1 31 Septic revision 4.4 23 4.4 23 Re-revision 1.8 No complication revision 0.2 i,2 1.7 2,30 Aseptic revision 6.1 i,31 6.1 31 Septic revision 4.4 i, 23 4.4 23 Re-revision 1.8 i,2,25 1.8 2,25 Quality Adjusted Life Years (QALYs)…”

“…If no occurrences were recorded for a health‐state, an estimated incidence of 0.1% was applied 37 . Both one‐ and 5‐year data for the mTHA cohort were extracted from available sources in the literature 2,21–26,30 . 1‐year RA‐THA data were queried from institutional records of a consecutive series of patients who underwent primary THA with a single experienced arthroplasty surgeon at the same institution, with the assistance of the fluoroscopy‐based ROSA® Total Hip System (Zimmer Biomet, Warsaw IN, USA).…”

Einfluss von Komorbiditäten auf die Revisionsrate im 1. Jahr postoperativ nach Primärimplantation einer Hüfttotalendoprothese

“…Bozic et al [8] konnten zwar zeigen, dass die mittelfristigen Revisionsraten (nach 5 bzw. 7 Jahren) seit 1998 deutlich gesunken sind, die Rate der Frührevisionen (nach 1 bzw.…”

Prediction of Complications and Surgery Duration in Primary Total Hip Arthroplasty Using Machine Learning: The Necessity of Modified Algorithms and Specific Data

“…Global trends indicate a rising prevalence of total hip arthroplasties (THA). Similarly, revision arthroplasties will increase, which are more expensive and are associated with poorer outcomes and more complications [1][2][3]. THA procedures in the United States are estimated to grow by 174% until the year 2030, while the number of THA revisions will double by 2026 [4].…”
