Osteochondral lesions (OCLs) in the ankle are more common than OCLs of the foot, but both share a similar imaging appearance. Knowledge of the various imaging modalities, as well as available surgical techniques, is important for radiologists. We discuss radiographs, ultrasonography, computed tomography, single-photon emission computed tomography/computed tomography, and magnetic resonance imaging to evaluate OCLs. In addition, various surgical techniques used to treat OCLs-debridement, retrograde drilling, microfracture, micronized cartilage-augmented microfracture, autografts, and allografts-are described with an emphasis on postoperative appearance following these techniques.
踝关节的软骨骨损伤（OCLs）比足部的 OCLs 更常见，但两者的影像学表现相似。放射科医生需要了解各种影像学检查方法以及现有的手术技术。我们讨论了 X 线摄影、超声、计算机断层扫描、单光子发射计算机断层扫描/计算机断层扫描和磁共振成像，以评估 OCLs。此外，还描述了用于治疗 OCLs 的各种手术技术，包括清创术、逆行钻孔术、微骨折术、微化软骨增强微骨折术、自体移植物和同种异体移植物，并重点介绍了这些技术后的术后外观。
