Abstract:
Objective:To evaluate arthroscopy-assisted tibial bone tunnel fixation combined with double-row anchors in the treatment of tibial eminence fracture.Methods:The 23 patients were retrospectively analyzed who had been treated at Department of Orthopedics, Beiing Shunyi District Hospital for tibial eminence fractures by arthroscopy-assisted tibial bone tunnel fixation combined with double-row anchors from October 2015 to December 2019. They were 15 males and 8 females, aged from 12 to 55 years (average, 35.5 years). All the injuries were unilateral (14 right and 9 left sides). According to the modified Meyers-McKeever classification, 2 cases belonged to type Ⅱ, 18 cases to type Ⅲ and 3 cases to type Ⅳ. Range of motion of the knee, Lysholm and International Knee Documentation Committee (IKDC) scores were observed before surgery, 1 month and 12 months after surgery. The anterior tibial slope angle (ATSA) on CT was measured preoperatively and 1 month after surgery for evaluation of fracture reduction.Results:All the 23 patients were followed up for an average of 23 months (from 12 to 52 months). Postoperatively, limited knee movement was observed in 2 patients and non-anatomic reduction in one patient. At 1 month and 12 months after operation, the Lysholm scores (61.4 ± 3.5 and 90.4 ± 4.3) and IKDC scores (69.6 ± 4.2 and 88.5 ± 3.0) were significantly improved compared with the preoperative values (45.4 ± 6.8 and 49.6 ± 3.9, respectively) ( P<0.05). ATSA was significantly restored from preoperative 4.2° ± 5.7° to -11.7° ± 2.9° at 1 month after operation ( P<0.05). Conclusion:In the treatment of tibial eminence fracture, arthroscopy-assisted tibial bone tunnel fixation combined with double-row anchors can achieve anatomical reduction and firm fixation, leading to satisfactory surgical outcomes.
