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 have shown highly reliability, validity, and is responsive to change in subjects with knee degeneration or with a knee injury.[1] 

Development[edit | edit source]

Historially it was known that as there were no specific paediatric outcome measures for knee pain, therefore the KOOS for adults was being used on children. It was only in 2012 when a group of researchers decided to look at the use of the adult KOOS with children.[2] They conducted cognitive interviews with 34 sweedish children between the ages of 10 and 16 years old. Cognitive interviews has been found to be the gold standard methodology for assessing the flaws in surveys due to lack of comprehnasion of the subjects. [3][4][5]

It was highlighted form this study that children who had undergone knee surgery of physiotherapy had a greater understanding of the medical terminlogy than those who had not, therefore they had better comprehension of the KOOS for adults. It was recommended that due to this lack of comprehension in those who were not familiar with the terminology or younger children that the KOOS would need to be modified for them. This study did not identify a cut off age that the KOOS adult should be used but to recommend that comprehension was limited in younger children. [6]

The development of the KOOS - Child has lead to there being 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 

Psychometric Properties[edit | edit source]

After the development of the KOOS - Child the psychometric properties were evaluated in 2014. This study looked at children who were seeking medical attention for knee symptoms between the ages of 7-16 years old. They looked at:

  • Construct validity - All of the hypothesis were confirmed therefore this indicated that there was excellend consruct validity.
  • Test-retest reliability - found that all test-retest's were excellent for all subscale except the symptoms scale which was slightly lower reliability. 
  • Responsivness - a hypothesis of a correlation of  ≥ 0.3 between the KOOS Child subscale scores and the Global Perceived Effect (GPE) was confirmed therefore confirming the responsivness of the KOOS Child.  
  • Interperability - there were no floor to ceiling effects found. Minimal important changes (MIC) were found to complement the 95% Confidence Intervals (CI), and the MIC were better than the smallest detectable change (SDC)  for subjects who reported they were 'better' and 'much better'

Overall the KOOS-Child shows excellent psychometric properties in all areas except internal consistency where the catagory 'symptoms' as this showed lower homogeneity, which is similar to the KOOS - Adult and this is explained as a patients can experience a wide variety of symptoms with knee conditions.  


Uses [edit | edit source]

Unlike the KOOS - Adult where certain conditions are recommended for it's use the KOOS - Child can be used in a broad population of children with different knee disorders. This page on paediatric knee disorders explorers different pathologies which it may be used for.
