Can Calcaneofibular Ligament Repair Correct Hindfoot Varus Alignment in the Management of Chronic Lateral Ankle Instability?
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHindfoot varus alignment is a risk factor for chronic lateral ankle instability (CLAI) and recurrent ankle instability following anterior talofibular ligament (ATFL) repair for CLAI. This study aimed to assess whether combining calcaneofibular ligament (CFL) repair with ATFL repair can correct hindfoot varus alignment and reduce recurrent ankle instability.
methodsThis study retrospectively examined 74 ankles from 71 patients with hindfoot varus alignment who had lateral ankle ligament repair for CLAI. Arthroscopic ATFL repair was performed on 37 ankles (from 36 patients) between 2018 and 2021 (ATFL-only group), whereas open ATFL and CFL repair were conducted on another 37 ankles (from 35 patients) between 2021 and 2023 (CFL-repair group). Long axial hindfoot alignment radiographs were utilized to measure tibiocalcaneal angles (TCA) pre- and postoperatively. The primary outcome includes recurrent ankle instability (i.e., respraining of the operated ankle after surgery), whereas the secondary outcome involves Self-Administered Foot Evaluation Questionnaire (SAFE-Q) scores.
resultsA comparison of patient demographics between the two groups revealed no marked differences. Additionally, pre- and postoperative TCA demonstrated that neither ATFL repair only nor CFL repair combined with ATFL repair corrected hindfoot varus alignment. Furthermore, no significant differences were observed in postoperative recurrent ankle instability and SAFE-Q scores between the two groups.
conclusionCombining ATFL and CFL repair could not correct hindfoot varus alignment, and this procedure for CLAI with hindfoot varus alignment was not more effective in reducing recurrent ankle instability than ATFL repair alone.
