Validation of the knee injury and osteoarthritis outcome score (KOOS) for the treatment of focal cartilage lesions
Osteoarthritis and Cartilage , 09/24/09

Bekkers JEJ et al. – This study illustrates the validity and reliability of the KOOS in measuring the clinical condition of patients after treatment of focal cartilage lesions. This study provides a basis for the use of the KOOS for future clinical research in cartilage repair.

Methods

40 patients (mean age 35 ± 12 years) treated for a focal cartilage lesion in the knee
Test–retest data collected with intermediate period of 2 days
Patients completed the Dutch KOOS and complementary questionnaires to evaluate the clinimetric properties of the KOOS in terms of internal consistency (Cronbach's alpha), reliability [intra-class-correlation (ICC) and Bland and Altman plots], construct validity (Spearman's rank correlation), floor and ceiling effects and responsiveness

Results

Cronbach's alpha of the KOOS subdomains and total score ranged from 0.74 to 0.96.
Overall ICC of the KOOS was 0.97 (subscales ranged from 0.87 to 0.95)
Bland and Altman plots showed small individual variance between two assessments in time
Spearman's rank correlations between the subscales of the KOOS and representative subscales of the SF-36
Lysholm and EQ-5D were high to moderate ranging from 0.43 to 0.70
No floor effect observed while the largest observed ceiling effect was 10.3%
