Evaluation of BMI With an All Inside Arthroscopic Broström Procedure for Chronic Lateral Ankle Instability: An Analysis of 113 Patients.

The all inside arthroscopic Broström surgical procedure for chronic lateral ankle instability is a minimally invasive procedure that is an option surgeons have when treating their patients. There have not been any studies analyzing the integrity of the repair to patients who have an elevated body mass index (BMI) to determine if the strength of the repair is adequate. We retrospectively evaluated a total of 113 consecutive patients who underwent this procedure. Fifty-nine patients had a BMI ≥30 kg/m; 54 had a BMI <30 kg/m. Unpaired t tests were performed to determine if a difference in American Orthopedic Foot and Ankle Society, visual analog scale, and Foot Function Index were encountered. Our findings indicate that there is no significant difference between patients with a BMI ≥30 kg/m compared to a BMI <30 kg/m who undergo an all-inside arthroscopic Broström procedure for chronic lateral ankle instability. This information may help surgeons decide what procedure options are available when treating chronic lateral ankle instability.
