Maltol inhibits Osteoarthritis (OA) development in mouse destabilization of the medial meniscus (DMM) model in vivo. Digital X‐ray image was used to detect the narrow of joint space (white arrows) and calcification of the cartilage surface (black arrows) in OA mice (A). Typical Safranin‐O staining of the cartilage and subchondral cortical bone (scale bar: 200 μm and 50 μm) (B). Diagrams showed the cartilage OARIS scores (C). The data in the figures represent mean values ± SD.^## P < .01, vs control group; **P < .01, vs the DMM group, n = 15
