Figure 3. — Prevalence of symptomatic Osgood-Schlatter disease (OSD) by age and sex. Prevalence peaked at approximately 12 years of age in both sexes (males, 13.8%; females, 11.4%), whereas another peak was observed in female participants at 9 to 10 years of age (9.2%-10.9%) and in male participants at 14 years (10.3%). The prevalence of symptomatic OSD increased significantly with older age in male participants and in total (P < .01). No increasing trend was noted for prevalence of OSD in female participants.
