Elevated risk of early reoperation in total hip replacement during the stage of unit closure: A population-based registry study of total hip and knee replacements in ­Finland, 1998–2011

Abstract: Background and purpose — The effects of launch or closure of an entire arthroplasty unit on the first or last patients treated in these units have not been studied Using a 3-year follow-up, we investigated whether patients who were treated at the launch or closure stage of an arthroplasty unit of a hospital would have a higher risk of reoperation than patients treated in-between at the same unitsPatients and methods — From the Finnish Arthroplasty Register, we identified all the units that had performed total joint arthroplasty and the units that were launched or closed in Finland between 1998 and 2011 The risks of reoperation within 3 years for the 41,748 total hip and knee replacements performed due to osteoarthritis in these units were modeled with Cox proportional-hazards regression, separately for hip and knee and for the launch and the closure stageResults — The unadjusted and adjusted hazard ratios (HRs) for total hip and knee replacements performed in the initial stage of activity of the units
