The ankle arthroscopy is widely used as an essential tool for the various ankle disorders. The use of arthroscopy has also been tried for the treatment of acute ankle fractures, in the hope of improving the postoperative outcome. It was initially thought that the properly reduced ankle fractures had generally acceptable outcomes, with a reported rate of 81% good to excellent results. However further investigation and longer term follow-up has shown more mixed and less encouraging results. Some patients have persistent pain and poor outcomes following open reduction and internal fixation (ORIF), although the cause of poor outcome is not clearly understood. It may be secondary to intra-articular injuries at the time of fracture, which occur in up to 88% of fractures. Ankle arthroscopy at the time of ORIF has been proposed to address these intraarticular injuries. Arthroscopy-assisted reduction and percutaneous screw fixation for syndesmosis injury has been performed as well by some surgeons. However the effectiveness of true arthroscopic reduction and internal fixation compared with ORIF for ankle fractures has yet to be determined, in spite of the advantages such as limited exposure, preservation of blood supply, and improved visualization of the pathology. Postoperative chronic pain and arthrofibrosis after ankle fracture are another good indication for ankle arthroscopy, which can be performed at the time of implant removal. In conclusion, the ankle arthroscopy is a safe adjunctive procedure for the treatment of ankle fractures. It can be performed as well for the evaluation and management of syndesmotic injury, and for persistent pain following the definitive treatment of ankle fractures.
