28 Chapter 2 Figure 3 : Change in total Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score 1, 2, 5 and 9 years after treatment with knee joint distraction. References can be used multiple times because of division in patient cohort and years of follow-up. CI: confidence interval; SD: standard deviation. The KOOS (Figure S2) and EQ-5D (Figure 4) were reported in 2 cohorts after 1 (n=42) and 2 (n=39) years, at both moments showing significant increases compared to pre-treatment, as did all KOOS subscales. The KOOS had an MD of 23.2 ( p< 0.001) and 24.9 ( p< 0.001) and EQ-5D of 0.15 ( p< 0.001) and 0.14 ( p< 0.001) after 1 and 2 years, respectively.
