National evidence linking robotic total knee arthroplasty to reduced 90-day readmissions, complications, and readmission costs.

ABSTRACT:

Purpose

To compare 90-day readmissions, complications, and resource use after robotic-assisted versus conventional total knee arthroplasty (TKA) in a contemporary, nationally representative cohort.

Methods

Retrospective cohort study using the Nationwide Readmissions Database (NRD) 2020-2022. Primary TKA identified from the PR1 field (ICD-10-PCS). Exclusions included non-elective admissions, revisions, bilateral procedures, age < 18, oncology/fracture/reoperation, COVID-19, and discharges after September. Readmissions within 90 days were categorized (prosthesis/SSI, mechanical/implant, VTE). 1:1 propensity score matching (nearest neighbor, caliper 0.01, no replacement) included demographics, comorbidities, hospital factors, and year.

Results

After matching, 96,982 pati
