Original Article



This study was designed to evaluate the outcome with and without repair of the AITFL by comparing two similar groups of patients with Weber B-type (Lauge–Hansen SE) fractures who were treated with similar operative methods except that the AITFL was not explored or either repaired in one group.

Materials and methods

A total of 288 patients with Lauge–Hansen SE4 ankle fractures were eligible for this study. In group 1 (n = 165), the AITFL was explored and the ruptured ligament sutured or the avulsion fracture fixed at the original insertion. In group 2 (n = 123), a similar operative method was used, but the AITFL was not explored. The postoperative medial tibiotalar clear space (TTCS) and congruence of the tibiotalar joint were measured and analyzed. The clinical outcome was measured using the Olerud–Molander (OM) scoring system with a minimum follow-up of 2 years for both groups.


No significant difference was found between these two treatment protocols using the postoperative TTCS, talar tilt, or OM functional score.


Our results suggest that exploration of the AITFL may not be needed in Weber B-type ankle fractures.
