Three adolescent patients with the tibial tuberosity avulsion fracture and the detailed descriptions of patient S histories, physical examinations, radio-graphic analyses and selection of treatments are presented. There is minimally two-year follow-up. All were injured in the basketball game and resulted in the Watson-Jones type III fracture. One of them received our treatment at a four-week’s delay after the traditional bonesetter manipulation and a herbal drug dressing. This particular type of fracture can be treated successfully, despite a delay in the treatment of at least one-month post injury, through an anatomic reduction procedure.
