A 40-year-old woman underwent right PAO for symptomatic dysplasia. Postoperative radiographs show good correction with no progression of osteoarthritis in 2 years. The preoperative dGEMRIC scan shows the superficial zone with lower dGEMRIC index, as indicated by the arrow. The 1-year postoperative scan shows the same region (arrow) with a lower dGEMRIC index in the superficial zone. The 2-year scan shows perhaps some recovery of the dGEMRIC index in the superficial zone.
