Cartilage damage Evaluation of Saf O stained cartilage sections showed a small increase in OARSI cartilage structural damage score in experimental (OA) knees compared to contralateral control knees (2.5 (95%CI: 0.6–4.4) points out of 12 points) in the PBS treated group, which was normalized in the cIL4-10 FP treated group (0.7 (95%CI: -0.6–2.0) points), at borderline significance (p = 0.057, Fig 8B ).
