Abstract
Purpose: There are various surgical interventions available for the management of Chronic lateral ankle instability (CLAI). The Broström-Gould procedure has gained widespread recognition among foot and ankle specialists for its favorable surgical outcomes. However, with advancements in anatomical understanding and medical technology, further enhancements to the effectiveness of the Gould procedure are warranted. This study introduces a all-inside modified “outside-in” Broström -Gould procedure as an alternative approach for addressing lateral ankle instability. Methods: From August 2020 to October 2022, 40 patients with lateral ankle instability who underwent arthroscopic repair of the modified “outside-in” Broström-Gould procedure were retrospectively analyzed. All patients received standard non-surgical treatment before surgery for more than 6 months without symptom relief. Visual Analogue Scale (VAS) and American Orthopaedic Foot and Ankle Society (AOFAS) and Karlsson-Peterson score were used to evaluate the postoperative effect. Results: All patients were followed up for (14.62 ± 2.04) months. One year after operation, all patients could walk normally, ankle instability sensation disappeared, varus stress test and anterior drawer test were negative. The VAS , AOFAS and Karlsson-Peterson scores of all patients were significantly better compared with those before operation, and the difference between before and after operation was statistically significant. Conclusions: The modified “outside-in” Broström-Gould procedure can effectively treat CLAI, which can obtain satisfactory results. The procedure is straightforward, the impact is minimal, and the aesthetics are pleasing.
