Time-lapse changes in the femoral and tibial cartilage in the non-contact area. Mankin score did not change significantly, and there was no statistical difference between the Im-B and Im-NS groups (a and d). The number of chondrocytes in the Im-B group significantly decreased at 3 days and 1 week in the femur and 3 days in the tibia (b and e). Cartilage thickness did not change, and it was not affected by immobilization and intra-articular administration in both contact and non-contact areas (c and f)
