- Traction apophysitis of the distal pole of the patella
- Patellar ligament is partially avulsed from the lower pole of the patella
- Traction tendonitis develops
- Similar pathology to Osgood-Schlatter disease of the tibial tuberosity
- X-Ray may show calcification of lower pole of patella in chronic cases
- Usually resolves spontaneously within 1 year
- Rarely requires surgical debridement of necrotic parts of tendon or excision of apophysis
