Background: Several different etiologies cause knee pain in the pediatric and adolescent population, including anterior knee/patellofemoral pain, patellar instability, anterior cruciate ligament (ACL) tears, meniscal tears, osteochondritis dissecans (OCD) lesions, and discoid meniscus. The purpose of the current study was to determine the relative morbidity of different causes of knee pain in children and adolescents using the International Knee Documentation Committee (IKDC) score. Methods: We performed a retrospective review of prospectively collected data of a cohort of pediatric and adolescent patients with knee pain who presented to a single surgeon. Each patient completed an IKDC questionnaire at the time of diagnosis and patients were grouped by diagnosis for analysis. Statistical analysis was performed to compare the IKDC scores of the 7 diagnostic groups, and a P-value <0.05 was considered significant. Results: The IKDC mean score for all 242 patients was 50.3±18.3. The mean IKDC score for patients with isolated meniscal tears was 41.2±16.0, combined ACL and meniscal injuries was 50.2±13.9, and isolated ACL tears was 48.1±14.1. The mean IKDC score for patients with symptomatic discoid meniscus was 46.3±13.2, anterior knee pain/patellofemoral pain was 49.0±17.4, patellar instability was 49.2±22.1, and OCD lesions was 62.2±19.5. Conclusions: The IKDC scores of most of the diagnostic groups were similar to the overall average score, with the notable exception of patients with OCD lesions exhibiting statistically significant less morbidity reflected by a higher IKDC score. Although symptoms in each individual clinical presentation may vary, knowledge of the relative morbidity of these diagnostic groups is valuable in counseling patients and their families regarding these common pediatric and adolescent sources of knee pain. Level of Evidence: Level IV.
