目的:对合并高度轴移不稳定的前交叉韧带损伤患者,在前交叉韧带重建的手术过程中,施行前外侧肌腱固定,分析该方法对恢复膝关节稳定性的作用与临床效果.方法:2015年6月至2015年12月,共140例患者诊断为前交叉韧带损伤,于我科接受手术治疗.其中,18例患者在麻醉下检查轴移试验表现为2+至3+,入选本研究.在手术过程中,在重建前交叉韧带的基础上,取髂胫束后方纤维做前外侧肌腱固定.患者在术后即刻、6个月和12个月时接受临床随访,采用KT-1000检查膝关节前后向稳定性,采用轴移试验评估膝关节旋转稳定性.使用Lysholm主观功能评分评估膝关节功能.结果:18例患者平均获得12.7±2.4个月随访,男性14例,女性4例,平均年龄28.3±7.1岁.至最终随访时,全部患者无膝关节不稳定主诉.前后向稳定性KT-1000检查患侧-健侧差值平均为2.3±0.7 mm,与术前(9.2±2.6mm)相比有显著差异(P＜0.01).术前麻醉下检查,13例患者轴移试验2+,5例患者3+.术后即刻检查轴移试验均为阴性.最终随访时,17例患者轴移试验阴性,1例患者1+,术后与术前相比有显著差异(P＜0.01).患者Lysholm评分术前平均为67.7±5.9(55至78),术后为89.0±4.6(75至95),术后相比术前有显著改善(P＜0.001).结论:对前交叉韧带损伤合并高度轴移试验阳性的患者,在重建前交叉韧带的同时,采用前外侧肌腱固定的方法,可有效改善轴移试验的结果,恢复关节稳定性,术后早期随访结果满意.“,”Objective To evaluate the early clinical outcomes of anterior cruciate ligament(ACL)reconstruction combined with anterolateral tenodesis procedure in patient with high grade pivot-shift after ACL injuries.Methods Among the 140 patients diagnosed as ACL injury and undergoing operations in our hospital between June and December 2015,18 presenting high grade pivot-shift 2+ or 3+ under anesthesia were included into this study.During their surgeries,the anterolateral tenodesis procedure using iliotibial tract ITB was applied together with ACL reconstruction.The anteroposterior stability of the knee was examined and pivot-shift test was conducted right after the operation as well as 6 and 12 months after that.The Lysholm score was used to evaluate the clinical function of their knees.Results The mean follow-up period of the 18 patients was 12.7 ± 2.4 months.There were 14 males and 4 females,with an average of 28.3 ± 7.1 years.No patients complained about unstable symptoms during the follow-up.The mean side-to-side difference of anteroposterior knee laxity assessed using KT1000 at 30 degree knee flexion was 2.3 ± 0.7 mm,which was significantly improved compared with preoperative assessment(9.2 ± 2.6 mm)(P＜0.01).For the preoperative examination,the pivot-shift examination indicated 2+ in 13 patients and 3+ in 5 patients.However,all were negative right after the operation.Seventeen patients presented negative pivot-shift at the final follow-up,while 1 had 1+ rotational laxity.Significant differences were found in the Pivot-shift test before and after the operation.The average Lysholm score improved significantly from 67.7 ± 5.9(ranging from 55 to 78)before the operation to 89.0-± 4.6(ranging from 75 to 95)after that.Conclusion The high grade pivot-shift rotational instability could be effectively restored using the anterolateral tenodesis procedure,in addition to ACL reconstruction.The early stage clinical outcomes indicate significant improvement of the knee stability postoperatively.
