A chronic sinus tract infection after suture anchoring of an
Suture anchors are increasingly used to fix soft tissue to bone. Favorable outcomes of the modified Brostrom operation (MBO) using suture anchors have been reported. However, to the best of our knowledge, few complications of suture anchors used in ankle surgery have been described.

Published in the journal Medicine, the authors report a rare case of successful treatment of a chronic sinus tract infection developing after the MBO using a suture anchor.

A healthy 18-year-old high school student presented with a chronic ulcerative wound in his right ankle 1 year after anterior talofibular and calcaneofibular ligament repair using a suture anchor at a local clinic. Clinical examination revealed a 1.5 × 2-cm-sized ulcerative wound, accompanied by a red-black discharge, on the anterior border of the right lateral malleolus. The wound could be approximated to the joint capsule level using a forceps.

A simple standing anteroposterior radiograph of the right ankle revealed mild, lateral soft-tissue swelling. MRI revealed that a sinus tract running from the wound to the talar body crossed the anterior joint capsule, and bone marrow edema surrounding the talus.

The sinus tract was removed along with the infected suture anchor. The wound was rendered zigzag-shaped and then simple suturing was performed and a short leg cast was applied. The wound healed completely by 4 weeks after surgery. The patient reported no complication or recurrence of infection at the 1-year follow-up.

Lessons learnt:-
To obtain wound healing, the chronic sinus tract must be removed. If the suture anchor is the cause of infection, it should be removed.
