Figure 1: (A) Graph showing evolution of knee pain, as measured by VAS (VASDA),over time. Mean ± standard error (SE) values of 50 patients treated withMSC. **p<0.01 (0-6 months); ***p<0.001(0-12 months) (ANOVA; Bonferronitest for paired values) (B) Graph showing evolution of knee pain associated tosports activity, as measured by VAS SPORT over time. Mean ± standard error(SE) values of 32 patients treated with MSC. Data from 18 patients were notincluded because they did not practice sports. p<0.001(ANOVA; Bonferronitest for paired values).
