前交叉韧带重建术中隐神经髌下支损伤不影响膝关节功能

Injury of infrapatellar branch of saphenous nerve during anterior cruciate ligament reconstruction does not affect knee function

目的探讨自体移植肌腱重建前交叉韧带术中隐神经髌下支损伤对膝关节功能的影响。方法回顾性分析2014年2月至2016年12月于河北医科大学第三医院手外科应用自体移植肌腱重建前交叉韧带术的病例,根据术后患者是否存在胫前皮肤感觉障碍,分为感觉障碍组和无感觉障碍组。t检验比较术后12个月膝关节Lysholm评分、VAS疼痛评分,卡方检验比较术后并发症发生情况。结果按照纳入排除标准,共有97例患者纳入本研究,感觉障碍组20例,无感觉障碍组77例。2组研究对象的性别、年龄、BMI、术前膝关节Lysholm评分、术前VAS及术中额外取肌腱等相比较,差异无统计学意义(P> 0. 05)。2组患者术后12个月的Lysholm评分、VAS疼痛评分相比,差异均无统计学意义(P> 0. 05)。结论自体移植肌腱重建前交叉韧带术中隐神经髌下支的损伤引起的胫前皮肤感觉障碍,不会对膝关节的功能产生不利影响。

Objective To investigate the effect of subacromial branch injury on knee joint function in anterior cruciate ligament reconstruction with autograft tendon. Methods Retrospective analysis of the cases of autogenous allograft reconstruction of anterior cruciate ligament in the Department of Handsurgery,the Third Hospital of Hebei Medical University from February 2014 to December 2016. According to the presence or absence of anterior tibial skin sensory disorder,the patients were divided into a sensory disorder group and a non-sensory disorder group. The postoperative knee Lysholm score,VAS pain score and postoperative complications were compared by t test and chi-square test. Results According to the inclusion and exclusion criteria,a total of 97 patients were enrolled in the study,20 in the sensory disorder group and 77 in the nonsensory group. There were no significant differences in gender,age,BMI,Lysholm scores,VAS or extra tendon occurrence between the two groups( P > 0. 05). There was no significant differences in Lysholm scores or VAS between the two groups 12 months after the surgery( P > 0. 05). Conclusion The anterior tibial skin sensory disturbance caused by saphenous nerve injury in the anterior cruciate ligament reconstruction with autograft tendon does not adversely affect the function of the knee joint.
