Table 8 Validity of the KOOS for the patient group with a revision of the 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 0.49* 0.39 0.50 0.30 0.54
PF 0.26 0.20 0.44* 0.32 0.36
SF 0.20 0.11 0.24 0.16 0.42
RF 0.12 0.18 0.14 0.24 0.26
RE 0.10 0.09 0.00 -0.01 0.15
MH 0.15 0.26 0.21 0.05 0.28
VT 0.15 0.28 0.18 0.05 0.39
GH 0.09 0.27 0.24 0.22 0.33
VAS for pain -0.47* -0.47 -0.29 -0.30 -0.21
  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.
