Gross appearance of the critical-sized bone defects. (A) Establishment of critical sized bone defect (Ø 5 × 10 mm) in rabbit femoral condyle (a), implantation of UiO-66 material (b), and wound closure (c). (B) Gross appearance of the rabbit femoral condyle bone defects of control (a-c) and UiO-66 implanted (d-f) groups at different evaluation times
