Knee pain.

Patient Data

Age: 14 years
Gender: Male

There is a comminuted avulsion fracture of the tibial tuberosity with proximal displacement of the tibial tuberosity. The patella appears to be superiorly displaced. Small knee joint effusion. Moderate prepatellar soft tissue swelling.

Comminuted avulsion fracture of the tibial tuberosity and the patella appears high-riding. Small knee joint effusion. There is also a small avulsion fracture of the inferomedial aspect of the patella, associated with an adjacent bone fragment.

Internal fixation of the previously demonstrated tibial tuberosity fracture with partial bony union present. No hardware failure. No periprosthetic lucency. No further focal osseous lesion. Skeletal alignment within normal limits. Small knee joint effusion.

Case Discussion

Tibial tuberosity avulsion fractures are uncommon injuries. They should be differentiated from Osgood-Schlatter disease.
