30 years with the Knee injury and Osteoarthritis Outcome Score (KOOS)

Life Sciences, Clinical Trials,
  • Thursday, February 15, 2024

The Knee Injury and Osteoarthritis Outcome Score (KOOS) is one of the most used Patient-Reported Outcome Measures (PROMs) assessing pain, function and quality of life in people suffering from knee injury and osteoarthritis.

During this webinar, the developer Professor Ewa Roos will give an overview of KOOS with focus on interpretability and use in clinical studies:

  • Learn about the KOOS development and the gap it filled. See how attitudes towards PROMs have changed, and reflect on the pros and cons of current outcome assessment methods
  • The KOOS 5-subscale structure is demystified. You will receive advice on how to optimize the use of KOOS and how to avoid multiplicity in a trial context
  • What level of problems does a KOOS subscale score of 78 represent? Insights include scoring direction, categorization, minimal important difference, patient acceptable symptom state, and treatment failure for clinical interpretation of KOOS scores
  • Discover the alternatives to the original KOOS: KOOS-12 and KOOS-Child

After administering and making the KOOS freely available for more than 20 years via a personal website, Professor Roos chose to partner with Mapi Research Trust, as of May 2023, for the distribution and licensing of the KOOS. The speakers will detail the practical conditions of access to the KOOS and share information on the available translations. The KOOS is free to use for non-funded and funded academic users. Commercial users and health care organizations must pay a fee. In both cases, authorization for use is always required.
