摘要: 探讨CT三维重建技术联合MRI检测球类运动致膝关节前交叉韧带(ACL)损伤重建术后移植物、周围结构与膝关节稳定性的关联性。选取238例球类运动致膝关节ACL损伤患者为研究对象,根据术后膝关节稳定性分为不稳组(31例)和稳定组(207例)。通过对比分析发现,不稳组移植物连续性阳性率、移植物走向松弛率、螺钉阳性率、隧道周围骨质阳性率、关节腔内情况阳性率均高于稳定组;不稳组术后移植物信号强度、胫骨前移、Blumensaat角高于稳定组,ACL角低于稳定组(P<0.05);移植物连续性、移植物走向、螺钉、隧道周围骨质、关节腔内情况、术后移植物信号强度、术后胫骨前移、术后ACL角、术后Blumensaat角均为重建术后膝关节不稳的影响因素(P<0.05);Logistic回归模型预测术后膝关节不稳的曲线下面积(AUC)为0.909。研究结果表明CT三维重建技术联合MRI检测膝关节ACL损伤患者重建术后移植物情况及周围结构与膝关节稳定性存在显著关联性,且在预测膝关节稳定性方面具有一定价值。

Abstract: The purpose of this article was to explore the correlation between the grafts, surrounding structures and the stability of the knee joint after reconstruction of the knee joint anterior cruciate ligament (ACL) injury caused by the CT three-dimensional reconstruction technology combined with MRI. According to the stability of the knee joint after the operation. A total of 238 patients with knee ACL injury caused by exercise were divided into unstable group (31 cases) and stable group (207 cases). Through comparative analysis, it was found that the positive rate of graft continuity, the rate of graft loosening, the positive rate of screw, the positive rate of bone around the tunnel, and the positive rate of intra-articular cavity of the situation in the unstable 418group was higher than those of the stable group. The postoperative graft signal strength, tibia anterior movement, and Blumensaat angle in the unstable group were higher than those in the stable group, while the ACL angle was lower than that in the stable group (P<0.05). Graft continuity, graft orientation, screws, bone around the tunnel, intra-articular conditions, postoperative graft signal intensity, postoperative tibial anterior movement, postoperative ACL angle, and postoperative Blumensaat angle were all the influencing factors of postoperative knee instability after reconstruction (P<0.05). The area under the curve (AUC) of the Logistic regression model for predicting postoperative knee instability was 0.909. It shows that CT three-dimensional reconstruction technology combined with MRI has a significant correlation with the stability of knee joint in the detection of the postoperative graft status and surrounding structures in patients with knee ACL, and has a certain value in predicting the stability of knee joint.
