Abstract

Background

Chronic ankle instability is frequent complication following ankle sprains. Anatomical reconstruction of the anterior talofibular ligament (ATFL) and the calcaneofibular ligament (CFL) with a gracilis autograft is a validated reconstruction technique. The signal-to-noise quotient ankle (SNQA) score evaluates graft maturation with MRI and has been shown to be reproducible and reliable. The goal of this study was to evaluate the process of ligamentization of the anatomical reconstruction of the ankle using the SNQA. The hypothesis was that the SNQA signal of the ATFL and the CFL would decrease over time.

Methods

A prospective cohort of patients who underwent arthroscopic anatomical ATFL-CFL reconstruction was included. All patients underwent a follow-up MRI examination 3, 6. and 12 months after surgery and the SNQA score was determined.

Results

Twenty consecutive patients were included. The SNQA score decreased significantly over time for the ATFL (p = 0.001), the CFL (p < 0.001) and for the fibular bone tunnel-graft interface (p = 0.02). The SNQA scores of the ATFL were significantly higher than those of the CFL at 3 months (p = 0.01), 6 months (p = 0.003) and 12 months (p < 0.001), and then those of the fibular tunnel-graft interface at 12 months (p = 0.003). There was no difference in the SNQA score between the CFL and in the fibular graft-bone tunnel interface at any of the follow up periods.

Conclusion

There is a process of graft maturation following anatomical ATFL and CFL reconstruction over time, which is faster for the CFL than for the ATFL during the first year.

期刊介绍： Foot and Ankle Surgery is essential reading for everyone interested in the foot and ankle and its disorders. The approach is broad and includes all aspects of the subject from basic science to clinical management. Problems of both children and adults are included, as is trauma and chronic disease. Foot and Ankle Surgery is the official journal of European Foot and Ankle Society. The aims of this journal are to promote the art and science of ankle and foot surgery, to publish peer-reviewed research articles, to provide regular reviews by acknowledged experts on common problems, and to provide a forum for discussion with letters to the Editors. Reviews of books are also published. Papers are invited for possible publication in Foot and Ankle Surgery on the understanding that the material has not been published elsewhere or accepted for publication in another journal and does not infringe prior copyright.
