A retrospective analysis of 18 patients with 19 acute tibial tubercle avulsion fractures was performed. Mean age at injury was 13 years 8 months. Mean follow-up time was 2 years 8 months. A group of 4 preadolescent patients ages 9 to 12 years at injury was identified. Participation in athletics, particularly basketball, resulted in 77% of fractures. There were one type IA, 3 type IB, 2 type IIA, 6 type IIB, 2 type IIIA, 4 type IIIB, and one type IV fractures. 15 fractures were treated with open reduction and internal fixation and 4 by closed reduction and cylinder cast immobilization. 3 cases (15.7%) of extensor mechanism disruption were noted, 2 patellar tendon avulsions and one quadriceps avulsion. Final outcome was good in all patients regardless of fracture type or treatment. There were no complications.
