膝关节韧带损伤术后系统性康复治疗效果与膝关节MRI影像学结果的关系

Relationship between Curative Effect of Systemic Rehabilitation Treatment after Knee Ligament Injury Surgery and MRI Imaging Results of Knee Joint

目的探讨膝关节韧带损伤术后系统性康复治疗效果与膝关节磁共振成像(MRI)影像学结果的关系。方法回顾性分析2017年8月至2018年8月本院膝关节韧带损伤术后行系统性康复治疗的90例患者临床资料,所有患者均进行MRI检查,按照移植物的信噪比分为移植物信号良好组(n=56)与移植物信号增高组(n=34),对比两组患者膝关节临床评估结果,探讨患者术后系统性康复治疗效果与膝关节MRI影像学结果的关系。结果移植物信号增高组内侧束与外侧束平均信噪比高于移植物信号良好组(P<0.05);移植物信号增高组骨性隧道扩大值高于移植物信号良好组(P<0.05);移植物信噪比与胫骨前内侧隧道、股骨前内侧隧道、胫骨后外侧隧道、股骨后外侧隧道扩大值呈正相关(r=0.683、0.696、0.728、0.625,P<0.05)。移植物信号良好组膝关节功能Lysholm评分、BBS评分、FAC评分高于移植物信号增高组(P<0.05);移植物信号良好组膝关节运动功能评分高于移植物信号增高组(P<0.05);移植物信噪比与患者膝关节Lysholm评分、BBS评分、协调能力、活动能力呈正相关(r=0.710、0.679、0.652、0.695,P<0.05)。结论移植物信噪比高低与膝关节韧带损伤术后系统性康复治疗效果存在相关性。

Objective To explore relationship between curative effect of systemic rehabilitation treatment after knee ligament injury surgery and magnetic resonance imaging(MRI)imaging results of knee joint.Methods The clinical data of 90 patients underwent systemic rehabilitation treatment after knee ligament injury surgery in the hospital from August 2017 to August 2018 were retrospectively analyzed.All patients underwent MRI.According to signal-to-noise ratio(SNR)of the graft.They were good signal graft group(n=56)and increased signal graft group(n=34).The clinical evaluation results of knee joints were compared between the two groups.The relationship between postoperative curative effect of systemic rehabilitation treatment and imaging results of knee MRI was explored.Results The average SNR of medial and lateral bundles in increased signal graft group was higher than that in good signal graft group(P<0.05).The expansion value of bone tunneling in increased signal graft group was higher than that in good signal graft group(P<0.05).The graft SNR was positively correlated with expansion values of tibia and femoral anterior medial tunnel,tibia,and femoral posterior lateral tunnel(r=0.683,0.696,0.728,0.625,P<0.05).The scores of knee function Lusholm,BBS,and FAC in good signal graft group were higher than those in increased signal graft group(P<0.05).The score of knee motor function in good signal graft group was higher than that in increased signal graft group(P<0.05).The graft SNR was positively correlated with scores of Lysholm and BBS,coordination ability,and activity ability(r=0.710,0.679,0.652,0.695,P<0.05).Conclusion There is correlation between SNR and curative effect of systemic rehabilitation treatment after knee ligament injury surgery.
