a-c Correlation between both OA scoring systems and assessment of the synovitis using the score according to Krenn et al., (2006). Correlation between both scoring systems (a). Depicted are the differences of the left (not surgically altered) and the right knee (surgically destabilized) of all animals (n = 12) (b). Furthermore, the differences between left and the right knees for the untreated control and the treated animals are shown separately (c). n = 6 per group. **p < 0.01
