Usefulness of Suture-Tape Augmentation Based on Intraoperative Ankle Stress Radiographs During Anatomical Ligament Repair for Chronic Lateral Ankle Instability

During the modified Broström procedure for chronic ankle instability, surgeons often experience cases with insufficiently restored mechanical stability even after anatomical ligament repair. In these cases, longer postoperative immobilization and delayed rehabilitation can be required, and a risk for recurrence of instability may persist. This study aimed to evaluate the clinical usefulness of suture-tape augmentation based on intraoperative stress radiographs during anatomical ligament repair for chronic ankle instability.
