Résumé

Introduction: Anterior tibial eminence (ATE) fractures are characterized by avulsion of the anterior cruciate ligament insertion. The aim of our study was to evaluate the long-term incidence of laxity and instability in the aftermath of these fractures. The secondary objective was to identify factors for instability. Hypothesis: ATE fracture in children is responsible for laxity and instability in the medium and long term. Material and methods: This retrospective, single-center study included 35 isolated fractures of the tibial intercondylar eminence during skeletal growth between January 2006 and January 2020. Analysis comprised demographics, laxity measured by GNRB™, range of motion and IKDC and Lysholm scores. Clinical reassessment was performed in 24 patients, the other 11 being interviewed by telephone. Results: Mean laxity on GNRB™ was 1.46 mm, and 3 patients had >3 mm differential with respect to the healthy knee. Mean IKDC score was 92.2 and mean Lysholm score 93.1. Four patients showed instability, 2 of whom required surgical management. There was no significant difference in occurrence of laxity according to fracture type or reduction quality. Mean follow-up was 5.9 years (range, 1.1-14.8). Discussion: Our clinical and functional results were in accordance with the literature. The long-term clinical results were satisfactory. ATE fractures require long-term follow-up to screen for instability and laxity on GNRB™. Level of evidence: IV, retrospective study.
