Compartment syndrome complicating tibial tubercle avulsion

Avulsion of the tibial tubercle is an uncommon physeal injury. Complications from this fracture are infrequent. Adolescent boys developed compartment syndrome after tibial tubercle avulsion. Injury to the soft tissue surrounding the tibial tubercle avulsion may be more extensive than is usually appreciated. The anatomy of the proximal tibia and the tibial tubercle with nearby branches of the anterior tibial recurrent artery suggest a predisposing factor for the development of compartment syndrome. Compartment syndrome should be added to the list of possible complications of tibial tubercle avulsion fractures.
