Summary

Simultaneous revision and primary total knee arthroplasty offers a favorable outcome. Most patients preferred the revision knee, suggesting this combined procedure is a safe alternative to staged surgeries.

Area of Science:

  • Orthopedic Surgery
  • Arthroplasty Research
  • Biomedical Engineering

Background:

  • Controversy exists regarding simultaneous versus staged bilateral total knee arthroplasty.
  • Revision total knee arthroplasties generally have lower success rates than primary procedures.
  • Evaluating simultaneous revision and contralateral primary total knee arthroplasties is crucial.

Purpose of the Study:

  • To assess the outcomes of simultaneous revision and contralateral primary total knee arthroplasties performed in the same surgical setting.
  • To compare the results of this combined procedure with staged contralateral procedures.
  • To determine patient preference and clinical effectiveness.

Main Methods:

  • A cohort of 75 patients underwent simultaneous revision total knee arthroplasty (TKA) and contralateral primary TKA.

  • A control group of 60 patients underwent unilateral revision TKA.
  • Follow-up averaged 5 years for the simultaneous group and 8 years for the control group.
  • Clinical and radiographic outcomes were assessed using the Knee Society rating system.

    • Main Results:

    • In the simultaneous group, knee scores improved by 48 points (primary) and 37 points (revision).
    • Most patients (65/75) preferred the revision knee over the primary knee in the simultaneous group.
    • The control group showed a 30-point improvement in knee score for revision, but all eventually underwent contralateral primary TKA.

    Conclusions:

    • Simultaneous revision and contralateral primary total knee arthroplasty demonstrates favorable outcomes.
    • Despite lower scores and motion, patient preference favored the revision side.
    • This combined procedure is a safe and effective alternative to staged bilateral knee arthroplasty.
