Abstract Background The aim of this study was to compare clinical and radiologic outcomes of a modified all-inside arthroscopic remnant-preserving technique of lateral ankle ligament reconstruction with traditional open reconstruction. Methods From January 2012 and March 2016, 60 eligible patients with chronic lateral ankle instability (CLAI) received all arthroscopic remnant-preserving reconstruction or open reconstruction of the anterior talofibular ligament and calcaneofibular ligament using semitendinosus autograft. They were divided into the arthroscopic group (n = 28) and the open group (n = 32). The American Orthopaedic Foot and Ankle Society (AOFAS),visual analog scale (VAS), and Karlsson scores and ankle range of motion (ROM) were used to evaluate clinical outcomes pre-operatively and at six and 12 months and the final follow-up of at least 24 months post-operatively, with SF-36 physical component summary (PCS) and mental component summary (MCS) scores evaluated for quality of life, and the anterior talar translation and talar tilt measurements for radiologic outcomes. Results There was no difference in pre-operative demographics between two groups (P > 0.05). At the final follow-up, the AOFAS, VAS, Karlsson, SF-36 PCS, and MCS scores improved significantly in both groups (P < 0.05). However, no significant difference was found in AOFAS (91.9 ± 6.8 vs 91.1 ± 5.5), VAS (2.7 ± 1.7 vs 2.5 ± 1.6), Karlsson (95.3 ± 6.7 vs 94.8 ± 6.5), SF-36 PCS (53.2 ± 6.1 vs 52.9 ± 5.7), and MCS scores (55.7 ± 5.8 vs 54.2 ± 5.4) between the two groups (P > 0.05). There was no significant difference in post-operative operated/non-operated ankle ROM between two groups (P > 0.05). No significant difference was observed in talar tilt angle (7.6 ± 4.1° vs 6.8 ± 3.6°) and anterior talar translation (5.8 ± 1.7 mm vs 5.7 ± 1.5 mm) between the two groups at the final follow-up (P > 0.05), although these two variables improved significantly in both groups (P < 0.05). No severe complications were encountered in both groups during the follow-up period. Conclusions The modified all-inside arthroscopic remnant-preserving technique of lateral ankle ligament reconstruction could produce excellent clinical and radiologic outcomes comparable with open reconstruction.
