文题释义:
内外翻畸形:膝关节内翻畸形是指双侧踝关节处于正常位置的内侧,同理,外翻是指双侧踝关节位于正常位置的外侧。正常的膝关节,压力是平均分布在关节面上的。而膝内外翻的人,体质量就过多集中于膝关节外侧,内侧关节面上,同时下肢力线不良,髌骨及股骨之间的摩擦增多,易导致髌骨软化。过度的压力和摩擦力,会导致膝关节外侧软骨面磨损,胫骨平台塌陷。
iASSIST智能辅助定位系统:与传统导航系统相比,操作更简单,使用更方便。不过,到目前为止,使用iASSIST智能辅助定位系统来完成全膝关节置换手术的报道比较少,本课题组使用的iASSIST系统的组成包括4个具备微小加速度计的感应器(Pod)、手术配套工具以及便携的平板计算机。在手术操作过程中,Pod能够感应速度与空间的变化,并利用无线传输技术把手术数据传输到平板计算机中,在定位系统和计算机交互运算后,就可以得到截骨的力线,这在理论上对医师在截骨前的导航与截骨后的评估非常有利。
 
摘要
背景:与常规膝关节置换手术相比,膝关节内外翻畸形患者全膝关节置换手术对适应证选择、假体选定、手术技巧准确性、围手术期管理的要求更高。
目的:对比分析iASSIST智能导航辅助定位系统与传统手术方式在膝关节内外翻畸形全膝关节置换中的临床应用效果。
方法:选择接受全膝关节置换的21例膝关节内外翻畸形患者,采用电脑随机抽样法分为2组,iASSIST智能导航辅助全膝关节置换组(A组)10例,传统全膝关节置换手术组(B组)11例。通过测量并比较2组术后冠状面髋-膝-踝角、冠状面股骨组件角、冠状面胫骨组件角、矢状面股骨组件角、矢状面胫骨组件角的偏移值评估手术精确性;通过比较2组术中出血量、手术时间、术后引流量、术后力线恢复程度、术后并发症发生率、住院时间、术后目测类比评分与美国膝关节协会评分评估疗效。
结果与结论:①2组患者术后下肢力线的髋-膝-踝角、冠状面股骨组件角、冠状面胫骨组件角、矢状面股骨组件角、矢状面胫骨组件角的偏移值均<3°,其中A组对内外翻畸形的矫正效果更好;②手术时间A组长于B组(P < 0.05),术后力线恢复程度A组优于B组(P < 0.05),术中出血量2组差异无显著性意义(P > 0.05),术后引流量A组多于B组(P < 0.05),住院时间B组长于A组(P < 0.05),术后引流量、术后1 d、1周的目测类比评分及美国膝关节协会评分B组优于A组(P < 0.05),术后并发症发生率、术后2周、1个月、3个月的目测类比评分及美国膝关节协会评分2组差异无显著性意义(P > 0.05);③结果表明,对于需要行全膝关节置换且膝关节内外翻畸形的复杂患者,使用iASSIST智能导航辅助全膝关节置换及传统全膝关节置换技术均可以获得较好的手术精度,其中iASSIST智能导航辅助全膝关节置换对术后下肢力线的重建效果更好。两种技术的远期疗效尚需要进一步研究。

Abstract:

BACKGROUND: Compared with conventional total knee arthroplasty (TKA), for patients with genu varum or genu valgus, indications, prosthesis choice, surgical accuracy and perioperative management during TKA should be paid more attention.

OBJECTIVE: To compare the clinical effectiveness of iASSIST-assisted TKA and traditional TKA in the treatment of genu varum or genu valgus.
METHODS: Twenty-one patients with genu varum or genu valgus undergoing TKA were selected, and were then randomized into two groups: iASSIST-assisted TKA (group A) or traditional TKA (group B). The surgical accuracy was compared between two groups by measuring the knee valgus angle of patients, and the angle between prosthesis components on the coronal and sagittal planes. Besides, the intraoperative blood loss, operation time, postoperative drainage, restored alignment, postoperative complications, hospitalization time, as well as Visual Analogue Scale and American Knee Society scores were recorded to assess the clinical effectiveness.
RESULTS AND CONCLUSION: (1) The deviation of hip-knee-ankle angle, frontal femoral component angle, frontal tibial component angle, lateral femoral component angle and lateral femoral component angle in the two groups was less than 3°, and the group A exhibited better corrective efficacy. (2) The operation time in the group A was significantly longer than that in the group B; the hospitalization time in the group was significantly shorter than that in the group B; the restored alignment in the group A was significantly superior to that in the group B; the postoperative drainage, as well as Visual Analogue Scale and American Knee Society scores at 1 day and 1 week postoperatively in the group B were significantly superior to those in the group A (all P < 0.05). There were no significant differences in the intraoperative blood loss, incidence of complications, as well as Visual Analogue Scale and American Knee Society scores at postoperative 2 weeks and 1 and 3 months between two groups (P > 0.05). (3) These results manifest that for the patients with genu varum or genu valgus, both iASSIST-assisted TKA and traditional TKA can obtain satisfactory surgical accuracy, and the former has advantage in restricting the alignment of lower limbs. However, the long-term efficacy needs to be explored in depth.
