Table 7 Validity of the KOOS for the patient group with a primary TKA

From: The Dutch version of the knee injury and osteoarthritis outcome score: A validation study

  KOOS Pain KOOS Symptoms KOOS ADL KOOS Sport/Rec KOOS QOL
SF-36 Subscale      
BP 0.62* 0.58 0.72 0.48 0.62
PF 0.66 0.56 0.83* 0.67 0.64
SF 0.39 0.35 0.48 0.26 0.51
RF 0.53 0.53 0.68 0.57 0.49
RE 0.22 0.27 0.39 0.37 0.23
MH 0.46 0.46 0.52 0.37 0.52
VT 0.61 0.48 0.52 0.31 0.49
GH 0.43 0.41 0.49 0.31 0.55
VAS for pain -0.70* -0.58 -0.59 -0.51 -0.27
  1. Validity is expressed by Spearman correlations between KOOS subscales, SF-36 subscales and VAS-pain. Abbreviations: OA; osteoarthritis, BP, bodily pain; PF, physical function; SF, social function; RF, role limitations because of physical problems; RE, role limitations because of emotional problems; MH, mental health; VT, vitality; GH, general health perception; ADL, Activities of daily living; QoL, Quality of life. In bold: convergente correlations that should be ≥ 0.60, In Italic: divergente correlations that should be ≤ 0.30. All other hypotheses are expected to be between 0.30 and 0.60. Correlations marked by * have to be 0.05 higher than the other convergent correlations.
