Predictors of Disparities in Patient-Reported Outcomes before and after Arthroscopic Meniscectomy

J Knee Surg DOI: 10.1055/s-0042-1743229The purpose of this study is to identify predictors of disparities in patient-reported outcome measures (PROMs) before and after arthroscopic meniscectomy. Knee injury and Osteoarthritis Outcome Score (KOOS) was used in this study. All patients who underwent single-knee arthroscopic meniscectomy from January 2012 to March 2018 performed by a single surgeon at an academic safety-net hospital were identified. We excluded patients who had undergone ipsilateral previous knee surgery, bilateral meniscectomy, or concomitant ligament, cartilage, or osteotomy procedures, and those with severe radiographic osteoarthritis in the operated knee, missing preoperative data, or military insurance. Data abstracted from medical records included demographics (age, sex, race, insurance type), clinical characteristics (body mass index, Charlson comorbidity index, and Kellgren-Lawrence [KL] grade), procedure codes, and KOOS assessed before and 90 days after surgery. Multivariable analyses investigated the associations between patient characteristics and the KOOS Pain, other Symptoms, and Function in activities of daily living (ADL) subscales. Among 251 eligible patients, most were female (65.5%), half were of nonwhite race (50.2%), and almost one third were insured by Medicaid (28.6%). Medicaid and black race were statistically significant (p < 0.05) predictors of worse preoperative values for all three KOOS subscales. Medicaid insurance also predicte...
