No Difference in Outcomes Between Suspensory (Fixed-Loop Cortical Button) Versus Expandable Anteromedial Femoral Fixation in Anterior Cruciate Ligament Reconstruction With Autologous Hamstring Tendons: A Prospective, Randomized, Controlled Study in Male Patients.
Arthrosc Sports Med Rehabil. 2021 Jun 24;3(4): e1155-e1163.Seventy patients with anterior cruciate ligament (ACL) ruptures were randomized to receive an ACL reconstruction procedure utilizing either suspensory femoral fixation (cortical button; n=35) or expandable femoral fixation (AperFix; n=35). The primary outcomes of interest included anteroposterior knee stability at 2 years follow up and femoral/tibial tunnel widening at 12 months follow up. Secondary outcomes of interest included the International Knee Documentation Committee (IKDC) score, Lysholm score, Tegner scale, and post-operative pain on a Visual Analog Scale (VAS). Results revealed similar radiological and clinical outcomes throughout the 24 month follow up period between the suspensory fixation and expandable fixation groups.
