What is a common cause of knee pain in growing adolescents?

Osgood-Schlatter disease is a common cause of knee pain in growing adolescents, particularly because it is related to the growth spurts that occur during this developmental stage. This condition results from overuse, which can lead to localized pain and inflammation at the tibial tuberosity, where the patellar tendon inserts. As adolescents engage in high-impact sports or activities, the repetitive stress on the knee joint can exacerbate this condition, leading to discomfort that is often reported as pain below the kneecap.

During periods of rapid growth, the quadriceps and surrounding musculature may develop at different rates, contributing to an imbalance that can further stress the knee. Additionally, the growth plate in this area is still developing, making it susceptible to irritation and inflammation. This provides a clear physiological rationale for why Osgood-Schlatter disease is prevalent among active, growing adolescents, particularly during periods of intense physical activity.

In contrast, conditions like patellar tendinitis or tendon rupture are less common or typically seen in older athletes rather than adolescents. Osteoarthritis generally does not manifest in this age group, as it is more associated with advanced age and wear-and-tear on the joints. Understanding these distinctions helps in recognizing Osgood-Schl
