文题释义:
可吸收挤压螺钉
:具有良好的可降解性能,由聚乳酸材料加工而成,置入体内12-18个月后,100%降解成乳酸(人体新陈代谢产物),再经过一系列的生物化学反应,最后降解成为二氧化碳和水,排出体外,术中使用之后患者无需进行二次手术,且材料具有良好的生物相容性,不会导致不良反应的出现。
前交叉韧带:又称前十字韧带,位于膝关节内,连接股骨与胫骨,主要作用是限制胫骨向前过度移位,它与膝关节内其他结构共同作用,来维持膝关节的稳定性,使人体能完成各种复杂和高难度的下肢动作。解剖和生物力学特点决定了前交叉韧带在人群分布、损伤机制及合并损伤等方面,显现出与其他膝关节损伤不同的疾病特征。

背景:治疗膝关节前交叉韧带损伤过程中,关节镜下进行重建修复是一种常用的手段,其中肌腱的固定是一项重要内容。
目的:探讨关节镜下可吸收挤压螺钉置入固定自体腘绳肌前交叉韧带重建的临床效果。
方法:纳入47例行前交叉韧带重建的患者,其中男27例,女20例,年龄18-48岁,均实施关节镜下可吸收挤压螺钉置入固定自体腘绳肌重建治疗。治疗后随访12个月,治疗前和治疗后1,3,6,12个月,分别对患者进行Lysholm、Tegner、IKDC评分,治疗后12个月对患者进行X射线正侧位片及MRI复查,并记录不良反应发生情况。
结果与结论:①术后患者膝关节不稳症状、关节痛均消失,未出现“打软腿”现象,行走步态恢复至正常水平,伤口均一期愈合,治疗后3,6,12个月的Lysholm、Tegner、IKDC评分均明显高于治疗前(P < 0.05);均未出现切口感染和神经损伤、深静脉血栓等,1例患者出现膝关节积血,其余患者治疗过程中均未出现任何不良事件;②治疗后12个月影像学检查显示,患者均未出现骨隧道扩大等现象,关节间隙未出现明显变化;③结果表明:可吸收挤压螺钉置入固定自体腘绳肌重建前交叉韧带创伤小、效果好,可显著改善患者肢体功能。

Abstract:

BACKGROUND: Arthroscopic reconstruction is a common method in the treatment of anterior cruciate ligament injury, in which tendon fixation is an important part.
OBJECTIVE: To investigate the clinical effect of absorbable screw fixation with autologous hamstring for anterior cruciate ligament reconstruction under arthroscopy.
METHODS: Totally 47 cases of anterior cruciate ligament reconstruction were included, containing 27 male patients and 20 female patients, aged from 18-48 years old, and all patients underwent the absorbable screw fixation with autologous hamstring implantation. After12-month follow-up, patients underwent Lysholm, Tegner, and IKDC scoring before treatment and after 1, 3, 6 and 12 months, respectively. Additionally, anterioposterior lateral X-ray and MRI reexamination were performed, and adverse reactions were recorded at 12 months after treatment.
RESULTS AND CONCLUSION: Postoperative knee instability symptoms such as “weak legs” walking gait recovered to normal levels, and the wound all reached the primary healing. Moreover, the Lysholm, Tegner and IKDC scores at 3, 6 and 12 months after treatment were significantly higher than those before treatment (P < 0.05). There were no incision infection, nerve injury, deep vein thrombosis and other adverse events except hemarthrosis of the knee joint in one case. After 12 months of treatment, the imaging examinations showed that there was no enlargement of the bone tunnel, and no significant change in the joint space. In conclusion, the absorbable screw fixation with autologous hamstring for the reconstruction of anterior cross ligament has good fixing effect and little trauma, and significantly improves the extremity function of patients.
