Revision total knee arthroplasty can yield good knee scores for most patients, despite challenges. Functional outcomes are reasonable, reflecting the complexities of revision surgery.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Reconstructive Surgery

Background:

  • Increasing rates of primary total knee arthroplasties lead to a rise in revision procedures.
  • Revision total knee arthroplasty (TKA) is becoming more common.

Purpose of the Study:

  • To retrospectively analyze outcomes of revision total knee arthroplasties.
  • Evaluate patient results from 1991 to 1999.

Main Methods:

  • Retrospective analysis of 71 patients undergoing 78 revision TKAs.
  • Knee Society Clinical Rating System used for evaluation.
  • Average follow-up of 3 years and 9 months.

Main Results:

  • Average knee score was 74.5, with 48% excellent (>85) and 22% poor (<60).

Related Experiment Videos

  • Functional outcomes (walking, stairs) averaged 48.3%.
  • Indications included pain, infection, patellar issues, and post-trauma.

    • Conclusions:

    • Revision TKA can achieve good knee examination results.
    • Functional outcomes are reasonable considering the complexity of revision surgery.
    • Revision TKA remains a challenging but often beneficial procedure.
