Occurs with rapid growth of child. Tendon insertion commonly partially rips up some of the tibial tubercle. This is a microfracture more than failure to mineralize as the tendon fails to grow as fast as the bones - increasing tension on the insertion point.
Adolescent boy with knee pain exacerbated by jumping who has tenderness/swelling specifically over the tibial tubercle, most consistent with Osgood-Schlatter disease (patellar tendon pulls on tibial tubercle repeatedly, leading to inflammation and repeated microfractures)
