Osteochondral lesions of the talus (OLT), also known as talar osteochondritis dissecans, is minor fracture to the articular cartilage of the talas subchondral bone it is associated with. The literature regarding its impact on patient demographics on post-operative associations of OLT-related repairs is lacking. The American College of Surgeons National Surgical Improvement Program (NSQIP) database was retrospectively reviewed, collecting data on patients with an OLT procedure between the 2008 through 2016. Univariate analysis was utilized to compare patient demographics, potential risk factors, comorbidities, hospital, and operative variables. Finally, Logistic regressions were utilized, adjusting associations of its risk factors and respective associations in a postoperative manner. A total of 491 patients with an OLT were collected for analysis. Hypertension requiring medication was a risk factor for readmission (<i>P</i> &#61; 0.039) and longer lengths of stay (<i>P</i> &#61; 0.021). The American Society of Anesthesiologists (ASA) classification significantly predicted increased rates of longer lengths of stay, with ASA class III being more likely than ASA class I (odds ratio &#91;OR&#93;: 4.8; 95&#37; confidence interval &#91;CI&#93;: &#91;1.7-14.2&#93;; <i>P</i> &#61; 0.004) or ASA class II (OR: 3.0; 95&#37; CI &#91;1.2-7.4&#93;; <i>P</i> &#61; 0.016) for patients to remain in hospital for longer than one day. Furthermore, patients who underwent an OLT with ASA class III underwent greater than average lengths of stay than ASA class I patients (0.54 &#177; 0.9 vs. 0.14 &#177; 0.5 days, respectively; <i>P</i> &#61; 0.011). Hypertension requiring medication and ASA classification predicted, in a positive manner, postoperative complications occurring in patients with an OLT. Despite being related with extended lengths of stay, only hypertension requiring medication were associated with increased rates of readmission. Orthopaedic surgeons may use these findings to counsel patients on their risk factors and subsequently prepare themselves for peri- and post-operative complications.
