    Abstract:
    BACKGROUND: Arthroscopically assisted reduction and internal fixation (ARIF) allows for the assessment of joint congruity following anatomic reduction, identification of occult intra-articular lesions, and treatment of traumatic intra-articular pathologies. The aim of this systematic review and meta-analysis was to provide evidence on whether ARIF is an alternative treatment protocol for ankle fractures. METHODS: The PubMed, Embase, and Cochrane Library databases were searched independently by two investigators from the inception dates to October 9, 2022, for comparative studies. The risk-of-bias tool of the Cochrane Collaboration for Randomized Controlled Trials and the methodological index for non-randomized studies (MINORS) were used for assessing the methodological quality. Outcomes were evaluated in terms of the Olerud-Molander Ankle Score (OMAS), American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale, post-operative complications, arthroscopic findings, Visual Analogue Scale (VAS) score, and operation time. Cochrane Review Manager Software 5.4 was used to perform the statistical analysis. RESULTS: A total of 10 trials involving 755 patients were included in this meta-analysis. The results revealed that ARIF for ankle fractures was superior regarding functional outcomes and VAS scores when compared with open reduction and internal fixation (ORIF). No significant difference was noted in the post-operative complication rate and the operation time between the ARIF and ORIF groups. A high incidence of chondral or osteochondral lesions (OCLs), ligamentous injuries, and loose bodies with ankle fractures was found by ankle arthroscopy. CONCLUSIONS: ARIF for ankle fractures might be beneficial to offer superior functional outcomes and VAS score than ORIF. Orthopedic surgeons should take a high incidence of OCLs and ligamentous injuries into consideration for the treatment of acute ankle fractures. We believe that with the increase in surgical experience, the occurrence of post-operative complications and the extension of operation time will no longer be a potential concern for surgeons.
