Fig. 1From: Icariin-conditioned serum combined with chitosan attenuates cartilage injury in rabbit knees with osteochondral defectEstablishment of osteoarthritis model on rabbits. A The rabbit was anesthetized in supine position. B The femoral condyle was exposed. C The cartilage defect was made on the femoral condyle. D The size and depth of the articular cartilage defects was made at a diameter of 4 mm and a depth of 3 mm. E The femoral condyle was shown after cartilage defect. F The characteristic of normal saline (NS) and chitosan-SH (CSSH) was photoed. G The characteristic of icariin-conditioned serum (ICS) and ICS-CSSH was photoedBack to article page
