Knee Injury and Osteoarthritis Outcome Score - Child
Introduction[edit | edit source]
The knee injury osteoarthritis score (KOOS) is an adult outcome measure used for assessing the patients perspectives of their knee pain and disability. This tool was developed initially to use on adults, which you can read about in more detail on this page. The KOOS pschometric properties has shown highly reliability, validity, and is responsiveness to change in subjects with knee degeneration or knee injury.[1]
Development[edit | edit source]
Hisorially it was known that as there were no specific paediatric outcome measures for knee pain the KOOS for adults was being used. It was only in 2012 when a group of researchers decided to research into the use of the adult KOOS with children.[2] They conducted cognitive interview with 34 sweedish children between the ages of 10 and 16 years old. Cognitive interviews has been found to be the gold standard methedology for assessing the flawd in surveys due to lack of comprehnasion of the subjects. [3][4][5]
It was highlighted that later developed to meet the needs of the paediatric knee, KOOS - Child, as it was identified that there were not child specific outcome measures for knee conditions and adult outcome measures were being used.
The KOOS - Child has 5 sections with 39 questions in total. These catagories are split into:
- Knee Problems
- How Painful
- Difficulty during daily activities
- Difficulty during sport and playing
- How has your injury affected your life
Within these catagories there are:
- 7 questions on symptoms
- 8 questions on pain
- 11 questions on activities
- 7 questions on sports and play, and
- 6 questions on quality of life
