前交叉韧带重建术后肌力恢复对膝关节功能的影响研究

Effect of Muscle Strength Recovery on Knee Joint Function after Anterior Cruciate Ligament Reconstruction

目的探讨前交叉韧带重建术后肌力恢复对膝关节功能的影响。方法方便选取2017年3月-2018年3月在该院行前交叉韧带重建术治疗的90例例前交叉韧带损伤患者作为研究对象,术后3个月测量患者肌力,分别应用Lysholm评分标准和Tegner评分评分标准评价患者膝关节功能,将Lysholm评分≥70分的患者设为A组(n=72例),<70分的患者设为B组(n=18例),比较A组、B组肌力指标检测结果。将Tegner评分≥5分的患者设为C组(n=69例),<5分的患者设为D组(n=21例),比较C组、D组肌力指标检测结果。结果术后随访3个月,A组患侧股四头肌肌力百分比(83.99±10.03)分、患侧腘绳肌肌力百分比(96.18±3.26)分、患侧股四头肌峰力距百分比(89.78±9.35)分、患侧腘绳肌峰力距百分比(94.36±4.81)分均高于B组(t=4.677、10.010、4.293、4.510,P<0.05),且C组上述肌力指标均高于D组(P<0.05)。结论行前交叉韧带重建术治疗的患者,术后肌力恢复越好,对膝关节功能产生的影响越小。

Objective To investigate the effect of muscle strength recovery on knee joint function after anterior cruciate ligament reconstruction.Methods Ninety patients with anterior cruciate ligament injury who underwent anterior cruciate ligament reconstruction in our hospital from March 2017 to March 2018 were convenient selected and enrolled.The muscle strength was measured 3 months after surgery.Patients with knee function were evaluated by the Lysholm score and Tegner score respectively.The patients with Lysholm score ≥70 were assigned to group A(n=72 patients),and those with <70 scores were group B(n=18 patients).Group B muscle strength index test results.Patients with a Tegner score of ≥ 5 were assigned to group C(n=69 patients),and patients with < 5 points were assigned to group D(n=21 patients).The results of muscle strength measurements in groups C and D were compared.Results After 3 months of follow-up,the percentage of muscle strength in the quadriceps muscle of group A(83.99±10.03)points,the percentage of muscle strength of the affected side(96.18±3.26)points,and the peak force of the quadriceps muscle of the affected side.The percentage of distance(89.78±9.35)points and the percentage of peak force of the affected side of the hamstring muscle(94.36±4.81)points were higher than those of the B group(t=4.677,10.010,4.293,4.510,P<0.05),and the above muscles of group C.The force index was higher than that of group D(P<0.05).Conclusion Patients with anterior cruciate ligament reconstruction have better muscle strength recovery and less impact on knee function.
