Abstract

Chondral or osteochondral avulsion injuries of the inferior pole of the patella in skeletally immature patients are common; however, superior pole injuries are very rare. Recognition of these injuries is important as the displaced bone-forming fragment will continue to enlarge and ossify, and may in some cases duplicate the patella. Moreover, these injuries often involve the extensor mechanism which is integral to the function of the lower extremity. We present a case of superior patellar sleeve avulsion fracture in an 8-year-old boy and review the radiographic and magnetic resonance imaging features and management of this injury.
