股薄肌肌腱移位结合带线锚钉固定修复膝内侧副韧带Ⅲ度损伤的临床疗效

The clinical effect of gracilis tendon transfer combined with wire anchor fixation in the repair of the degree Ⅲ injury of the medial collateral ligament of knee

目的分析股薄肌肌腱移位结合带线锚钉固定修复膝内侧副韧带Ⅲ度损伤的临床疗效。方法回顾性分析2015年3月至2017年6月于我院手术治疗膝内侧副韧带Ⅲ度损伤的38例病人的临床资料,均采用股薄肌肌腱移位结合带线锚钉内固定加强修复膝内侧副韧带手术治疗,收集并比较其术前及术后12个月的Lysholm评分、Tegner评分、侧方应力试验结果,以评价其临床疗效。结果术后12个月复查的X线片示所有病人内固定位置良好,均未出现感染,侧方应力试验均转为阴性。38例病人术前的Lysholm评分为(37.48±10.40)分,范围为25~64分,术后改善至(91.30±6.72)分,范围为82~96分,手术前后Lysholm评分比较,差异有统计学意义(t=2.512,P=0.019)。38例病人术前的Tegner评分为(4.25±2.10)分,范围为3~6分,术后改善至(8.52±4.38)分,范围为8~9分,差异有统计学意义(t=2.370,P=0.021)。结论通过股薄肌肌腱移位结合带线锚钉内固定修复治疗膝内侧副韧带Ⅲ度损伤的临床效果良好。

Objective To analyze the clinical effect of gracilis tendon transfer combined with wire anchor fixation in the repair of the degree Ⅲ injury of the medial collateral ligament of knee.Methods From March 2015 to June 2017,38 cases of the degree Ⅲ medial collateral ligament injury of knee treated by transposition of the gracilis tendon combined with the internal fixation with wire anchor to repair the medial collateral ligament of knee were retrospectively analyzed.Knee joint function was evaluated by the Lysholm score,the Tegner score,and the medial stress test for 12 months.Results X-ray was reviewed 12 months after operation.All patients had a good internal fixation position and no infection occurred.The medial stress test turned negative.The preoperative Lysholm score was increased from 37.48±10.40(25-64) preoperation to91.30±6.72(82-96) at 12th month postoperation(t=2.512,P=0.019).The preoperative Tegner score was increased from 4.25±2.10(ranging from 3 to 6) preoperation to 8.52±4.38(ranging from 8 to 9) postoperation(t=2.370,P=0.021).Conclusion The clinical effect of the treatment of the degree Ⅲ injury of the medial collateral ligament of knee with gracilis tendon transfer and internal fixation with wire anchor is satisfactory.
