We present a sleeve fracture at the superior pole of the patella in a 12-year-old boy. Sleeve fractures at the inferior pole
of the patella have been well described in the orthopedic and radiologic literature. However, a similar injury at the superior
pole of the patella is relatively rare. We hope that awareness of this unusual injury and its imaging findings will allow
timely diagnosis and intervention.
