A 13-year-old soccer player presents with a four-week history of aching anterior right knee pain that lasts about 24 hours following training and matches. There is no history of direct trauma, but he has experienced a significant growth spurt during the last six months. Clinical examination reveals swelling and tenderness over the tibial tuberosity, absence of a knee joint effusion, stable knee ligaments and no patellofemoral irritability. X-ray shows a normal tibial tuberosity, with overlying soft tissue swelling.
