Insights

The American Academy of Orthopaedic Surgeons guidelines incorrectly dismissed viscosupplementation for knee osteoarthritis. Methodological flaws in interpreting minimum clinically important improvement (MCII) led to this flawed recommendation.

Area of Science:

  • Orthopedics
  • Rheumatology
  • Clinical Practice Guidelines

Background:

  • The 2013 American Academy of Orthopaedic Surgeons (AAOS) guidelines recommended against viscosupplementation for knee osteoarthritis.
  • This recommendation was based on the failure to meet the minimum clinically important improvement (MCII) criterion.
  • Concerns exist regarding the AAOS's methodology in assessing MCII-based results.

Purpose of the Study:

  • To critically evaluate the AAOS's 2013 guidelines concerning viscosupplementation for knee osteoarthritis.
  • To assess the appropriate use of minimum clinically important improvement (MCII) in clinical decision-making.
  • To advocate for a revised guideline approach that considers research limitations and treatment alternatives.

Main Methods:

  • Review of the AAOS 2013 guidelines methodology for knee osteoarthritis treatment.
  • Analysis of the application and interpretation of minimum clinically important improvement (MCII) data.
  • Evaluation of current research standards for MCII as a clinical decision-making tool.

Main Results:

  • The AAOS methodology exhibited significant flaws in obtaining, displaying, and interpreting MCII-based results.
  • Current research indicates MCII should serve as a supplementary tool, not the sole basis for clinical decisions.
  • The guidelines' condemnation of viscosupplementation may be premature due to methodological limitations.

Conclusions:

  • The AAOS 2013 guidelines' recommendation against viscosupplementation for knee osteoarthritis requires re-evaluation.
  • Clinical decision-making should not solely rely on MCII, especially given methodological concerns.
  • Updated guidelines should acknowledge MCII's limitations and consider viable treatment options for osteoarthritis.
