| Summary: | Despite the modified Broström Procedure (MBP) being the gold standard for surgical treatment of chronic ankle instability (CAI), there is little data regarding factors that impact rehabilitation time. This retrospective analysis includes 67 consecutive Modified Broström Procedures (MBPs). Records were reviewed to define patient factors associated with increased time to return to activity (RTA). Of the 67 cases reviewed, 23 patients underwent reconstruction of the calcaneofibular (CFL) with a semimembranosus allograft in addition to repair of the anterior talofibular ligament (ATFL) with a suture tape. There were no significant demographic or clinical differences between these two groups. All patients had a minimum follow-up of 12 months. The mean age and body mass index (BMI) of the cohort was 44.7 years and 33.7 kg*m2, respectively, with a ratio of females to males of 2.35:1. Males began weight bearing as tolerated (WBAT) in a walking boot 1.08 weeks earlier than females (p = 0.053). Those with a BMI ≥ 35 kg/m2 RTA in normal shoe gear 0.50 weeks later (p = 0.443). Workers’ compensation cases were correlated with RTA (+0.431, p < 0.001). The number of completed physical therapy (PT) sessions had no significant correlation with time of return to activity (+0.063. p = 0.622). The post-operative complication rate was 7.5% (Five patients). No odds ratios were found to be statistically significant. Overall, these results suggest that semitendinosus allograft is safe, and corroborates prior evidence that worker's compensation cases are independently linked to a delayed return to activity. This data can potentially guide post-operative expectations and preparation of clinical trials.
