Radiographic changes in the left knee joint (L). (a) The normal control group shows a healthy knee joint with a smooth articular cartilage surface and normal joint space (arrowhead). (b) The MIA-treated group demonstrates OA alternations such as a remarkable narrowing of the joint space (arrowhead), erosion, subchondral sclerosis (curved arrow), and osteophyte (black arrow). (c) The MIA + BMMSC-treated group shows nearly restored normal joint space (arrowhead) and cartilage surface.
