Osteochondritis dissecans (OCD), classified under ICD-10-CM code M93.2, is a joint disorder that affects the subchondral bone, leading to the separation of bone segments due to insufficient blood supply. Although uncommon, with an incidence of 6 to 29 per 100,000 individuals annually, OCD poses significant challenges in military populations due to its impact on physical readiness and operational performance. In the general population, the condition most frequently affects the knee, particularly the medial femoral condyle, and is prevalent among active, skeletally immature individuals aged 12-19 years (Chau et al., 2021). In military settings, repetitive microtrauma from high-impact activities such as running, marching, and combat tasks can exacerbate OCD lesions, increasing the risk of chronic disability and early attrition (Andriolo et al., 2020). Cases requiring surgical intervention or resulting in functional limitations often lead to Medical Evaluation Board (MEB) processing and disability separation, highlighting the importance of timely diagnosis and effective management strategies. To address these readiness challenges, the Medical Standards Analytics and Research (MSAR) team is conducting a study to evaluate early adverse attrition (EAA) among active duty enlistees accessed between FY 2019-2023 via an approved OCD medical waiver. The waivered cohort, composed of individuals diagnosed with OCD (M93.2), is compared to demographically matched medically qualified (MQ) enlistees. EAA is assessed at both 1-year and 3-year intervals using Kaplan-Meier survival analysis, with results stratified by service branch and sex to identify differential attrition patterns. Sub-analysis of disability discharge is conducted using chi-square or analogous non-parametric tests to evaluate significance of associations and relative risk. Findings from this study aim to inform evidence-based modifications to DoD medical standards, ensuring a balance between recruitment needs and long-term health outcomes for service members.
