Tibial spine fractures are uncommon injuries affecting the insertion of the anterior cruciate ligament on the tibia. They typically occur in skeletally immature patients aged 8 to 14 years and result from hyperextension of the knee with a valgus or rotational force. Diagnosis is based on history, physical examination, and standard radiographs. The use of MRI can identify entrapped soft tissue that may prevent reduction. Open or arthroscopic repair is indicated in patients with partially displaced fractures (>5 mm) with one third to one half of the avulsed fragment elevated, in patients who have undergone unsuccessful nonsurgical reduction and long leg casting or bracing, and in patients with completely displaced fractures. Arthroscopy offers reduced invasiveness and decreased morbidity. Suture fixation and screw fixation have produced successful results. Suture fixation can eliminate the risk of fracture fragment comminution during screw insertion, the risk of neurovascular injury, and the need for hardware removal. Suture fixation is ideal in cases in which existing comminution prevents screw fixation.
