Surgical treatment of an osteochondral lesion associated with stress fracture of the tarsal navicular: a case report.

We surgically treated an osteochondral lesion associated with a stress fracture of the tarsal navicular. The surgical procedure involved the confirmation and complete resection of the lesion under direct vision, followed by the transplantation of block-shaped iliac bone grafts. The postoperative computed tomography scan showed that the lesions had disappeared, the grafted bone had fused, and the stress fracture had healed. However, the tarsal navicular joint surface was slightly irregular. The patient was able to resume her sports activities 15 weeks after surgery. We have described a novel method to reconstruct the tarsal navicular after osteochondral lesion resection.
