Predicting readmissions after total knee arthroplasty (TKA) is crucial for improving patient care. Current models show variable performance and require better reporting and validation for clinical use.

Area of Science:

  • Orthopedic Surgery
  • Health Services Research
  • Biostatistics

Background:

  • The aging US population necessitates increased total knee arthroplasty (TKA) procedures.
  • Healthcare initiatives like Comprehensive Care for Joint Replacement emphasize efficient care transitions.
  • Predictive models for post-TKA readmissions are actively being developed.

Purpose of the Study:

  • To systematically review existing models predicting readmissions after TKA.
  • To identify risk factors associated with TKA readmissions.
  • To assess the quality and performance of these predictive models.

Main Methods:

  • Systematic literature search across five databases.
  • Adherence to PRISMA and TRipod standards for systematic reviews and prediction models.

  • Quality assessment using established appraisal tools.

    • Main Results:

    • 29 models were selected, with 6 reporting C-statistics ranging from 0.51 to 0.76.
    • Average 30-day and 90-day readmission rates were 5.33% and 7.12%.
    • Three novel significant risk factors for readmission were identified.

    Conclusions:

    • Existing TKA readmission models demonstrate inadequate performance measurement and reporting.
    • Future models require systematic calibration, external validation, and transparent reporting for clinical implementation.
    • Development of improved predictive techniques is essential for enhancing post-TKA care.
