Anatomic and checkrein tenodesis reconstruction techniques have been described as a means of treatment for chronic lateral ligament instability in the ankle. The current article describes a hybrid procedure using the most advantageous concepts of both techniques for use when insufficient normal ligament remains to fashion a direct repair of the anterior talofibular ligament (ATFL).
Purpose:
The authors report the results at a minimum 1-year follow-up of 57 patients who underwent a hybrid anatomic lateral ligament reconstruction technique in the ankle.
Study Design:
Case series; Level of evidence, 4.
Methods:
Fifty-seven patients underwent a hybrid anatomic lateral ligament reconstruction procedure under the care of the senior author. All patients were assessed preoperatively and postoperatively using the Foot and Ankle Outcome Score (FAOS) and Short Form–12 (SF-12) outcome score. The mean patient age at the time of surgery was 28 years (range, 17-65 years), including 39 male and 18 female patients. The mean follow-up time was 32 months (range, 12-47 months).
Results:
The FAOS improved from 58 points preoperatively to 89 points postoperatively (P < .01). The SF-12 score improved from 48 points before surgery to 80 points at final follow-up (P < .01). All patients achieved mechanical stability at final clinical follow-up; 7 patients (12%) demonstrated functional instability. Functional instability was found to significantly influence not returning to sport at the previous level.
Conclusion:
This hybrid anatomic lateral ligament reconstruction technique using a peroneus longus autograft to substitute the native ATFL provides an alternative to anatomic reconstruction when direct repair is not possible.
