ABSTRACT
Objective:To investigate the efficacy of arthroscopic reduction and double-tunnel button fixation in the treatment of fractures of the tibial intercondylar eminence in children.Methods:From January 2019 to June 2022, 8 children with fracture of the tibial intercondylar eminence were treated at Orthopedics Department, Shenzhen Children's Hospital with arthroscopic reduction and double-tunnel button fixation. They were 6 boys and 2 girls, with an age of (8.4±1.9) years. Injured sites: 4 left knees and 4 right knees. Their operation time, intraoperative blood loss, knee flexion and extension, and complications were recorded. Their Lysholm scores were compared between preoperation and the last follow-up.Results:The operation time was (161.9±57.9)min. All patients were followed up for (12.1±5.7) months. The intraoperative blood loss was 3.5 (1.0,4.3)mL. Their knee flexion was 145.0°±5.0° and extension 0.9°±1.2° after operation. All their incisions healed at one stage, with no postoperative infection or other complications. Their preoperative Lysholm score [(20.3±15.8) points (from 2 to 54 points)] increased significantly to (99.3±1.0) points (from 98 to 100 points) after operation ( P<0.05). Conclusions:Arthroscopic reduction and double-tunnel button fixation is effective for fractures of the tibial intercondylar eminence in children, leading to limited complications, limited bleeding and a low infection rate.
