Introduction: A lateral ankle sprain is one of the most frequent reasons for consultation at the emergency trauma unit. Numerous surgical procedures have been described with long-term outcomes that differ.
Hypothesis: The long-term results of anatomical repair of the anterior talofibular ligament (ATFL) and the calcaneofibular (CFL) ligament are better, with less secondary radiological osteoarthritis than non-anatomical repair.
Materials and methods: A review of the literature after a minimum follow-up of 10 years was performed to analyze the clinical and radiological results of direct anatomical repair (Broström, Duquennoy) and non-anatomical repair (Watson Jones, Evans, Castaing). Thirteen articles were selected.
Results: Eight hundred and one ankles were evaluated after a mean follow-up of 15.3 years. The functional outcome was better after anatomical repair but with recurrent instability. Loss of range of motion and secondary osteoarthritis was more frequent after non-anatomical repair.
Conclusion: Anatomical repair of the lateral collateral ligament of the ankle resulted in a better functional outcome and less secondary osteoarthritis than non-anatomical repair.
Study design: Review of the literature; level of proof IV.
Keywords: Anatomic repair; Lateral ankle instability; Lateral reconstruction; Long term.
