Riassunto dello studio

Sixty patients with acute or chronic lateral ankle ligament injuries were randomized to receive either arthroscopic treatment (n=29) or open Broström procedure (n=31). The primary outcome of interest was the accurate placement of suture anchors for lateral ankle ligament repair, assessed by measuring the distances of bone tunnels to various bony landmarks (fibular tip, anterior-inferior tibiofibular ligament insertion, and Fibular obscure tubercle) and the safe angle of anchor implantation on postoperative CT scans. Secondary outcomes included the successful identification and suturing of the inferior bundle of the anterior talofibular ligament (iATFL) and arcuate fiber. All outcomes were assessed postoperatively using CT scans. Overall, the results of the study revealed no significant differences between the arthroscopic and open-locating groups in terms of the primary and secondary outcomes. The conclusion of the study is that using the lowest point of the fibula (LPF) under arthroscopy as a bony landmark is a reliable method for the precise and efficient placement of suture anchors and suturing of the iATFL.
