Values with different superscripts differs significantly between the groups; Uppercase alphabets (P ≤ 0.01); lowercase alphabets (P ≤ 0.05).

MPH = tissue morphology; MT = matrix staining (metachromasia); CD = cell distribution; SF = surface architecture; INB = integration with subjacent bone; TDM = tidemark; SBA = subchondral bone abnormalities; AC = abnormal calcification; VRT = vascularization in repair tissue; MJA = mid/deep zone assessment.
