Tibial tubercle avulsion fractures most commonly occur in adolescent boys and usually result from pushing off or landing while jumping. These fractures are relatively uncommon but can have a significant functional effect. The purpose of this study was to determine the long-term outcome with return to play in 8 adolescent basketball players with at least 4 years of postoperative reconditioning. Results with return to play at the preinjury level are favorable after treatment of acute tibial avulsion fractures in adolescent basketball players. Long-term outcome was excellent in all patients regardless of fracture type. Open reduction and internal fixation using 1 or 2 cancellous bone screws achieved union in all cases.
