(A) Frequency distributions for BO. Bars represent the number of patients with BO within a 5% range. The BO is calculated by 3D quantitative MRI using the ratio of intra-lesional bone volume at 12 months to the baseline (post-debridement) cartilage lesion volume at 1 month post-treatment. More than 80% of patients had less than 10% BO. (B) Characterization of intra-lesional BO. First row: example of spotty BO; maximum bone height was ∼25% of the surrounding cartilage thickness. Second row: example of planar BO; maximum bone height was ∼50% of the surrounding cartilage thickness. Third row: example of pre-existing BO recurring at 12 months.
