Ankle Arthroscopy as an Adjunct to the Management of Ankle Fractures.

Background: Ankle fractures are one of the most common injuries managed by orthopedic surgeons. Although the etiology of posttraumatic osteoarthritis in anatomically reduced ankle fractures is not completely known, several studies suggest that undetected intra-articular pathology at the time of injury may play a role. The purpose of this study is to report the operative findings of ankle arthroscopy as an adjunct to ankle fracture open reduction and internal fixation.

Methods: A retrospective review was performed of all ankle fractures treated consecutively at our institution by a single surgeon from August 2010 to October 2019, which were found using codes. A total of 84 patients met our inclusion criteria for whom patient demographics and clinical history were collected. Pre- and postoperative diagnoses from every operative report were noted as well as intra-articular intervention made during the time of arthroscopy.

Results: The study included 49 men (58.3%) and 35 women (41.7%), with a mean age of 39.0 (range, 12-69; SD = 15.0) years. Sixty-three patients (75%) had new diagnoses detected by the addition of ankle arthroscopy. The most common new pathology seen arthroscopically were osteochondral lesions (n = 36, 41.9%) and posterior malleolus fractures (n = 28, 32.6%). Thirty-four patients had a total of 40 additional arthroscopic procedures in conjunction with their fracture management. Complications were noted in 13 patients, with hardware removal (n = 8) being the most common (62%).

Conclusion: Ankle arthroscopy can act as a significant diagnostic and prognostic tool and can help address intra-articular injuries without adding considerable cost or serious adverse events.

Level Of Evidence: Level IV, retrospective case series.
