The authors report 20 cases of injuries involving the proximal tibial epiphysis (16 avulsion fractures of the tibial tubercle, 4 epiphyseal fractures), occurring in adolescents engaged in athletics, in 3/4 of the cases. Sixteen displaced fractures needed open reduction and internal fixation with screw(s). Leg shortening (12 mm) occurred in a 14 year-old male with a displaced fracture of both the tibial tubercle and proximal epiphysis, in which premature ossification had taken place; fixation with Kirschner wires would have been the treatment of choice before closure of the tibial epiphysis. At follow-up, function was acceptable in all cases; all the patients had returned to full daily activity and no further surgical procedures were needed. Long-term knee laxity became obvious in one patient, however, with repeated fracture of the tibial tubercle. Associated ligamentous and meniscal tears should therefore be sought on early clinical examination and confirmed by arthroscopy or arthrotomy after surgical fixation.
