Abstract
The Modified Broström has become the gold standard for operative management of chronic
lateral ankle instability. Despite overall good clinical outcomes with this procedure,
recent biomechanical data have called into question the strength and durability of
this technique. Accordingly, the addition of suture tape to the Modified Broström
construct has been described in an attempt to more closely recreate the natural biomechanical
properties of the ankle lateral ligament complex. We performed a systematic review
of the literature was using PubMed, Embase, and CINAHL to identify English-language
articles from 2009 to present discussing outcomes with the augmented Modified Broström
technique. A total of 4 studies (2 retrospective cohort studies, 2 case series) involving
156 patients with Modified Broström with augmentation met inclusion criteria. Average
follow-up time was 13.8 months. Of the 3 studies reporting patient-reported outcome
measures both pre- and postoperatively, there was a significant improvement in all
measures (p < .05). Two studies compared the Modified Broström directly with and without augmentation,
one of which found a statistically significant difference in the Foot and Ankle Ability
Measure in favor of the augmentation group (93.1 vs 90.5, p = .027), while American Orthopaedic Foot and Ankle Society score was not significantly
different (p > .05) between the 2 procedures across studies. There were no significant differences
in complications between techniques. Modified Broström with suture tape augmentation
for chronic lateral ankle instability can produce good short-term clinical outcomes
with few complications, comparable to the Modified Broström alone.
