A case with simultaneous tibial tuberosity fracture and patellar tendon avulsion in a 16-year-old boy is presented. Surgery was performed for open reduction, screw fixation and patellar tendon repair, and protected with a wire loop to restore the extensor mechanism. The wire loop was removed at 2 months postoperatively. The fracture healed at 5 months after surgery and the patient regained the full range of movement of the knee at 5 months.
