Masson staining, Goldner’s trichrome staining, and Safranin O-fast green staining were observed in each group at each postoperative time point (Scale bar: 50 μm). Masson staining showed new collagen fibers in blue and mature bone in red. Goldner’s trichrome staining showed mineralized bone in green and immature bone in orange–red. Safranin O-fast green staining shows cartilage as red and bone as blue
