Arthroscopic Suture Fixation of Anterior Cruciate Ligament Avulsion Fracture of the Tibial Eminence: Four Cases Report

Background: In treating avulsion fractures of the tibial eminence of the anterior cruciate ligament (ACL), surgical reduction and internal fixation is necessary for patients with a widely displaced fragment. The study presents clinical results for arthroscopic suture fixation in treating ACL avulsion fractures of the tibial eminence. Methods: Between July 2000 and January 2002, four patients with ACL avulsion fractures in the tibial eminence were treated with the arthroscopic suture fixation technique. All the fractures were classified type Ⅲ in the Meyers classification. The average follow-up period was 27.5 months (range, 24-36 months). Follow-up assessment included Lysholm knee scores, Tegner activity scores, International Knee Documentation Committee (IKDC) score, KT-1000 arthrometer and radiographic evaluation. Results: The mean Lysholm score at final follow-up was 97 (range, 92 to 100). All 4 patients (100%) showed good or excellent results at final assessment. The mean Tegner score at final follow-up was 7.25 (range, 7 to 8). At the final follow-up of IKDC scores, there were three grade A (normal) and one grade B (near normal) scores. All four fractures reached to solid union within 3 months. There was no significant complication such as arthrofibrosis, loss of initial fixation or wound infection for all patients. Conclusions: Arthroscopic reduction and suture fixation of these 4 patients restored the length of the ACL, stabilized all fragments, promoted early motion, minimized morbidity, and showed good fracture union.
