a The magnetic resonance imaging (MRI) obtained showed diffuse signal intensity (SI) decreases across the entire right head of the femur. b The magnetic resonance imaging (MRI) obtained showed that subchondral zones of low SI were observed in medial tibial plateaus on both sides. c Close reductions and internal fixations with fibular shaft graft and s-pins were performed on the subchondral stress fractures. At 2 years postoperatively, the patient still had considerable depressed deformation in the right femoral head
