Rotational acetabular osteotomy (RAO) has been reported to be effective in improving symptoms and preventing osteoarthritis (OA) progression in patients with mild to severe develomental dysplasia of the hip (DDH). However, some patients develop secondary OA even when the preoperative joint space is normal; determining who will progress to OA is difficult. We evaluated whether the preoperative cartilage condition may predict OA progression following surgery using T2 mapping MRI.

关节软骨值的术前 T2 映射 MRI 可预测旋转髋臼截骨术后骨关节炎的进展。

据报道，旋转髋臼截骨术 (RAO) 可有效改善轻度至重度髋关节发育不良 (DDH) 患者的症状并预防骨关节炎 (OA) 进展。然而，即使术前关节间隙正常，一些患者也会发生继发性骨关节炎；确定谁将进展为 OA 是困难的。我们使用 T2 映射 MRI 评估了术前软骨状况是否可以预测手术后 OA 的进展。
