Abstract:Objective To investigate the influence of triple-tunnel Femoral-Intrafix fixed double bundle reconstruction on knee stability and function in patients with anterior cruciate ligament injury. Methods Fifty-four patients with anterior cruciate ligament injury of knee joint admitted to Huabeiyiliao Jiankangjituan Fengfeng Zongyiyuan from November 2019 to November 2020 were selected and divided into observation group and control group by random drawing method, with 27 cases in each group. Single-tunnel single bundle reconstruction was used in the control group, while triple-tunnel Femoral-Intrafix fixed double bundle reconstruction was used in the observation group, and both groups were followed up for 24 months after surgery. The operation and postoperative conditions of the two groups were compared, the differences in joint function and knee stability before operation and 24 months after operation between the two groups were compared, and the incidence of postoperative complications between the two groups was recorded. Results The time of hospitalization, weight bearing, and getting out of bed in the observation group were shorter than that in the control group (P<0.05). At 24 months after operation, International Knee Documentation Committee score and Lysholm score of the two groups were higher than those before operation, and those of observation group were higher than those of control group (P<0.05). At 24 months after operation, the positive rates of the front drawer test and Lachman test in the two groups were lower than those before operation, and the positive rate of the axial shift test in the observation group was lower than that before operation and control group (P<0.05); there was no statistical significance in the positive rate of the axial shift test in the control group compared with that before operation (P>0.05). There was no significant difference in the total incidence of complications between the two groups (P>0.05). Conclusion Triple-tunnel Femoral-Intrafix fixed double bundle reconstruction can restore the function and rotational stability of the patient’s knee joint better, and is worthy of clinical promotion.
