Abstract:
Purpose:This study reports on a series of patients with chronic lateral ankle instability that underwent the Broström procedure with suture tape augmentation and allowed early unrestricted weight-bearing in a simple stirrup brace.
Materials and Methods:This retrospective study was conducted on 36 patients (22 males and 14 females of mean age 34 years [range 23~48 years]) with chronic lateral ankle instability treated using the Broström procedure using suture tape augmentation and inferior extensor retinaculum reinforcement with a fiber-wire connected to a SwiveLock screw inserted into the talus. When possible, patients started unrestricted weight-bearing in a stirrup brace from the third postoperative day. Demographics and functional outcomes, including American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot, visual analogue scale (VAS), and satisfaction scores, were recorded. In addition, varus stress radiographs obtained before and 24 months after surgery were compared. Patients were followed for a mean 29 months (range 25~40 months).
Results:Mean AOFAS ankle-hindfoot scores increased from 51 points preoperatively to 92 points at final follow-up, and mean VAS decreased from 6.8 to 1.2 points. Mean patient satisfaction scores were 8.7 at 12 months and 9.6 at 24 months. Stress radiographs demonstrated that talar tilt decreased from a mean 18 degrees preoperatively to 7 degrees at 24 months.
Conclusion:Early unrestricted weight-bearing in a stirrup brace following the Broström procedure with suture tape augmentation is a successful protocol for treating chronic lateral ankle instability.
