Predictors of Osteochondral Lesions of the Talus in Patients Undergoing Broström-Gould Ankle Ligament Reconstruction.

Chronic ankle instability is associated with intra-articular and extra-articular ankle pathologies, including osteochondral lesions of the talus. Patients with these lesions are at risk for treatment failure for their ankle instability. Identifying these patients is important and helps to guide operative versus nonoperative treatment. There is no literature examining which patient characteristics may be used to predict concomitant osteochondral lesions of the talus. A retrospective chart review was performed on patients (N = 192) who underwent a primary Broström-Gould lateral ankle ligament reconstruction for chronic ankle instability from 2010 to 2014. Preoperative findings, magnetic resonance imaging, and operative procedures were documented. Patients with and without a lesion were divided into 2 cohorts. Fifty-three (27.6%) patients had 1 lesion identified on preoperative magnetic resonance imaging. Forty (69.0%) of these lesions were medial, 18 (31.0%) were lateral, and 5 patients had both. Female sex was a negative predictor of a concomitant lesion (p = .013). Patients were less likely to have concomitant peroneal tendinopathy (30.2% vs 48.9%; p = .019) in the presence of a lesion. However, sports participation was a positive predictor of a concomitant lesion (p = .001). The remainder of the variables (age, body mass index, smoking, trauma, duration, contralateral instability, global laxity) did not show a significant difference. In patients who underwent lateral ankle ligament reconstruction, females were less likely to have a lesion than males. Patients with peroneal tendinopathy were less likely to have a lesion compared with patients without. Additionally, athletic participation was a positive predictor of a concomitant lesion.
