We report a case of en bloc avulsion fracture of tibial tuberosity and Gerdy's tubercle. A 40 -year-old male suffered from an acute pain in his left knee after a motorcycle accident. Simple radiographs showed an avulsion of the tibial tuberosity. Confirmed by CT scans. MRI evaluation revealed no intra-articular associated pathology. Open reduction and internal fixation with 1 screws were performed under antero-lateral approach to expose the Gerdy's tubercle with ITB. At 2 months postoperative, he could walk and complained of no difficulty in activities on daily living with full range-of-motion of the knee. We believe that the injury was caused by violent contraction of the tensor fascia lata or gluteus maximus. Preoperative planning including the determination of the extent of fracture and recognition of concomitant injury is a prerequisite for appropriate treatment.
