Osgood-Schlatter disease is a traction-related osteochondrosis of the tibial tubercle that occurs in active adolescents during growth spurts. Repeated pulling of the patellar tendon through the quadriceps pulls on the tibial tubercle’s growth plate, causing inflammation and small fragments to form or separate. This presents as anterior knee pain right below the kneecap, especially with running, jumping, kneeling, or stairs, and a tender bump over the tibial tubercle. Imaging may show fragmentation of the tibial tubercle, though X-rays can be normal early on. It’s usually self-limiting and improves with rest, activity modification, and NSAIDs; most kids recover as they finish grow. In contrast, Sinding-Larsen-Johansson disease affects the inferior pole of the patella, Scheuermann disease is a spinal condition with wedged vertebrae causing kyphosis, and Van Neck-Odelberg disease relates to osteochondrosis around the distal femur, not the tibial tubercle.
