After Anterior Cruciate Ligament Injury, Patients With Medicaid Insurance Experience Delayed Care and Worse Clinical Outcomes Than Patients With Non-Medicaid Insurance.

Purpose: To evaluate the effects of socioeconomic factors on the operative treatment of anterior cruciate ligament injuries and outcomes following surgical reconstruction. Methods: A retrospective cohort study of primary anterior cruciate ligament reconstruction surgeries at a single institution performed from 2011 to 2015 with minimum 2-year follow-up was conducted. Patient demographics, insurance type, workers' compensation status, surgical variables, International Knee Documentation Committee score, and failure were recorded from chart review. Education level and income were obtained via phone interview. Differences between functional outcome were compared between Medicaid and non-Medicaid groups. Results: In total, 268 patients were included in the analysis (43 patients in the Medicaid group and 225 patients in the non-Medicaid group, overall mean follow-up of 3.1 ± 0.8 years). The Medicaid group demonstrated lower annual income ( Conclusions: Patients with Medicaid insurance were seen in the clinic significantly later after initial injury and had worse outcomes compared with patients with other insurance types. Also, patients in higher annual income brackets had significantly better clinical outcomes scores at a minimum of 2 years postoperatively. Level of Evidence: Level III, retrospective cohort study.
