case_images: The x-ray examination (Figure 1) revealed bilateral aseptic necrosis of the femoral head (Ficat Type IV), and the patient had a history of KBD for more than 20 years without treatment. From the preoperative period to the last follow-up, the patient's bilateral hip mobility and functional scores improved significantly (Figure 4 and Table 1), and no adverse events such as hip pain, prosthesis loosening or dislocation were found at the final follow-up.
case_images: Pre-operative standing and walking status of the patient. (Figure notes: The patient had bilateral hip inversion and showed a cross gait when walking).
