个体化手术入路在膝关节镜半月板成形术中的临床价值

Clinical value of individualization portal for knee arthroscope meniscoplasty

目的 探讨个体化手术入路在膝关节镜半月板成形术中的临床应用价值。方法 回顾性分析100例行膝关节镜半月板成形术患者的临床资料，其中采用常规手术入路50例（A组），采用个体化手术入路50例（B组）。比较两组手术时间、疗效、并发症发生率。结果 B组手术时间明显短于A组[（28.8 ± 3.1）min比（39.5 ± 5.4）min]，差异有统计学意义（t= 12.151，P〈0.01）。A组和B组优良率比较差异无统计学意义[94%（47/50）比96%（48/50），χ2= 0.522，P〉0.05]。B组半月板、软骨损伤发生率明显低于A组[2%（1/50）比14%（7/50）]，差异有统计学意义（χ2= 4.891，P〈0.05），两组血肿发生率比较差异无统计学意义（P〉0.05）。两组无韧带损伤、感染、神经血管损伤、下肢深静脉血栓、器械损坏、滑膜瘘等发生。结论 膝关节镜半月板成形术使用个体化手术入路可方便操作，缩短手术时间，减少半月板与软骨损伤发生率，但对术后疗效及其他并发症无明显影响。

Objective To study the clinical application value of individualization portal for knee arthroscope meniscoplasty.Methods The clinical data of 100 patients who had underwent knee arthroscope meniscoplasty were retrospectively analyzed. In the patients, 50 cases were performed with routine portal （group A）, and other 50 cases were performed with individualization portal （group B）. The operation time, curative effect and incidence of complications were compared between 2 groups.Results The operation time in group B was significantly lower than that in group A： （28.8 ± 3.1） min vs. （39.5 ± 5.4） min, and there was statistical difference （t= 12.151, P〈0.01）. There was no statistical difference in excellent and good rate between group A and group B： 94% （47/50） vs. 96% （48/50）, χ2= 0.522, P〉0.05. The incidence of meniscus and cartilage injury in group B was significantly lower than that in group A： 2% （1/50） vs. 14% （7/50）, and there was statistical difference （χ2= 4.891, P〈0.05）. There was no statistical difference in incidence of hematoma between 2 groups （P〉0.05）. There was no ligament injury, infection, vascular and nerve injury, deep vein thrombosis, instrumentation damage and synovial fistula.Conclusions The individualization portal for knee arthroscope meniscoplasty is more convenient. It can shorten operation time and decrease meniscus and cartilage injury. But it has no influence on clinical effect and other complications.
