Rigid tape dynamic fixation in conservative treatment of acute anterior talofibular ligament tear: A retrospective cohort study.

Abstract

Objectives: This study aims to compare results of rigid tape (RT) dynamic fixation and static fixation in conservative treatment of acute anterior talofibular ligament (ATFL) tear.

Patients and methods: Between September 2021 and December 2021, a total of 91 patients (41 males, 50 females, mean age: 28.5±6.5 years, range, 18 to 40 years) who were diagnosed with ATFL tear and underwent rigid tape (RT) or cast/brace rehabilitation protocol were retrospectively analyzed. The patients were divided into two groups as the RT group (n=36) and the control group (n=55). Follow-up (FU) was performed at six months. Outcomes included pain (Numerical Rating Scale [NRS]), ankle function (American Orthopaedic Foot & Ankle Society [AOFAS] hindfoot score), deviation of center of gravity (DCG), and symptoms after returning to sports.

Results: The difference at each time point of pain, AOFAS, DCG and SRS between the two groups was statistically significant (p<0.05 for all). Only one patient at Week 12 in the RT group had pain in the lateral side of the ankle, while 36 patients at Week 12 and 21 patients (18 in the medial side) at FU had pain in the control group.

Conclusion: Our study results suggest that RT dynamic fixation can accurately lock the ATFL function and may prevent pseudo-stability, so as to quickly repair injury, restore function, and return to sports earlier.
