Abstract:
Objective: To investigate the early effectiveness of three-point suture technique in treatment of anterior cruciate ligament (ACL) tibial eminence avulsion fracture by arthroscopy. Methods: Between January 2016 and December 2017, 12 patients with ACL tibial eminence avulsion fractures underwent arthroscopic fixation of avulsion fractures with Ethibon suture using three-point suture technique. There were 9 males and 3 females, with an average of 36.4 years (range, 18-50 years). The fracture caused by traffic accident in 10 cases and sports in 2 cases. Among them, 1 patient was old fracture and 11 was fresh fracture. According to the modified Meyers-McKeever classification criteria, the fractures were rated as type Ⅲ in 7 cases and type Ⅳ in 5 cases. There were 2 cases of medial collateral ligament injury and medial meniscus injury. The preoperative International Knee Documentation Committee (IKDC) score was 37.9±4.7 and Lysholm score was 46.0±3.7. Results: All operations completed smoothly. The operation time was 45-70 minutes (mean, 61.3 minutes). The incisions healed by first intention in all patients. The hospitalization stays ranged from 4 to 9 days (mean, 5 days). All patients were followed up 3-20 months (mean, 9.3 months). The anterior drawer test, Lachman test, and axis shift test in all patients were negative after operation. At last follow-up, the IKDC score was 89.7±2.5 and Lysholm score was 90.2±1.9, which were significantly higher than those before operation ( t=-30.94, P=0.00; t=-33.03, P=0.00). At last follow-up, the X-ray films showed 9 cases of fracture anatomical reduction and 3 cases of almost anatomical reduction, and 12 cases of fracture healing. Conclusion: For ACL tibial eminence avulsion fracture, arthroscopic three-point suture technique can effectively restore the stability of knee joint and obtain satisfactory early effectiveness.
