Open Reduction and Internal Fixation Using a Posterolateral Approach for a Posterolateral Osteochondral Lesion of the Talus: A Case Report

Osteochondral lesions of the talus (OLT) are characterized by damage to the articular cartilage and subchondral bone, resulting in ankle pain. In open surgical management of OLT, selecting an appropriate approach to the talus based on lesion location is a major challenge. Posterolateral OLTs are rare, and no previous studies have reported open surgery using a posterolateral approach for these lesions. This report describes a 24-year-old man with a posterolateral OLT who underwent open reduction and fixation via a posterolateral approach and achieved a favorable outcome. This case provides clinically relevant information for considering open surgical approaches to posterolateral OLT.
