Interleukin-6 (IL-6) is a pleiotropic cytokine and associated with the pathogenesis of femoral head deformity in patients with ischemic osteonecrosis of the femoral head. The femoral head deformity results from increased bone resorption and decreased bone formation during the repair process. However, the role of IL-6 in the bone healing process following ischemic osteonecrosis is unknown. The purpose of this study was to determine the effects of IL-6 deletion on bone repair following ischemic osteonecrosis. As results, IL-6 knock-out mice show higher bone volume after ischemic osteonecrosis. In addition, IL-6 deletion increases the number of osteoblasts and new bone formation following ischemic osteonecrosis.
