Arthroscopic reduction and fixation of avulsion fracture of the tibial attachment of the anterior cruciate ligament

In treating avulsion fracture of the tibial attachment of the anterior cruc iate ligament, surgical reduction and fixation of fractured bone is necessa ry for patients who have a wide displacement of bone fragment (i.e., types III and IV in the Meyers classification). Our arthroscopic technique allows the creation of bone tunnels on the medial and lateral sides of the bone f ragment from the medial side of the tibial tubercle without using special e quipment. At surgery, fixation wire is prepared into a loop, pulled into th e joint space, and the loop is opened within the joint. This makes intra-ar ticular manipulation easy, and the bone can be reduced more accurately. Thi s arthroscopic technique decreases surgical invasion of the joint, allows g ood postoperative range of motion without problems, and is useful in preven ting extension limitation due to dislocation of the anterior portion of the fragment.
