UASSIGNED:本研究旨在探讨全膝关节置换术(TKA)后组件排列与短期临床结果之间的相关性。
未经评估:来自地区医院的50名TKA患者被纳入研究。从手术后1周内获得的放射学数据测量以下组件对齐:髋-膝-踝角度(HKA),股骨远端内侧角(MDFA),胫骨近端内侧角(MPTA),股骨屈伸角度(FEA),胫骨倾斜角(TSA),股骨旋转角(FRA)和胫骨旋转角(TRA)。特殊外科医院(HSS)膝关节评分系统用于评估1年后的临床结果,将患者分为三组(优秀,好和不好)根据HSS分数。统计学分析采用差异分析和线性相关分析。
UNASSIGNED:结果显示三个患者组之间的MDFA(p=0.050)和FEA(p=0.001)存在显着差异。还发现总HSS与FEA仅具有中等相关性(r=0.572,p<0.001),但FEA与疼痛评分呈正线性相关(r=0.347,p=0.013),函数得分(r=0.535,p=0.000),ROM分数(r=0.368,p=0.009),肌肉评分(r=0.354,p=0.012)和稳定性评分(r=0.312,p=0.028)。较大的MDFA与较低的FE畸形评分相关(r=-0.289,p=0.042),TSA对ROM有积极影响(r=0.436,p=0.002)。此外,FRA的变化导致FE畸形评分随之变化(r=0.312,p=0.027),肌肉力量评分随着TRA的增加而增加(r=0.402,p=0.004)。
UNASSIGNED:结果表明,FEA在TKA后的临床结局中起着重要作用。手术技术和工具可能需要改进以准确地调整FEA以改善关节功能和患者满意度。
UNASSIGNED: This study aimed to investigate the correlation between component alignment and short-term clinical outcomes after total knee arthroplasty (TKA).
UNASSIGNED: 50 TKA patients from a regional hospital were enrolled in the study. The following component alignments were measured from radiological data acquired within 1 week after surgery: hip-knee-ankle angle (HKA), medial distal femoral angle (MDFA), medial proximal tibial angle (MPTA), femoral flexion-extension angle (FEA), tibial slope angle (TSA), femoral rotational angle (FRA) and tibial rotational angle (TRA). The Hospital for Special Surgery (HSS) knee scoring system was used to assess clinical outcomes after 1 year, with patients being divided into three groups (excellent, good and not good) according to the HSS scores. Difference analysis and linear correlation analysis were used for the statistical analysis.
UNASSIGNED: The results showed significant differences in MDFA (p = 0.050) and FEA (p = 0.001) among the three patient groups. It was also found that the total HSS had only a moderate correlation with FEA (r = 0.572, p < 0.001), but FEA had a positive linear correlation with pain scores (r = 0.347, p = 0.013), function scores (r = 0.535, p = 0.000), ROM scores (r = 0.368, p = 0.009), muscle scores (r = 0.354, p = 0.012) and stability scores (r = 0.312, p = 0.028). A larger MDFA was associated with lower FE deformity scores (r = -0.289, p = 0.042) and the TSA had a positive influence on the ROM (r = 0.436, p = 0.002). Also, changes in FRA produced a consequent change in the FE deformity score (r = 0.312, p = 0.027), and the muscle strength scores increased as TRA increased (r = 0.402, p = 0.004).
UNASSIGNED: The results show that the FEA plays a significant role in clinical outcomes after TKA. Surgical techniques and tools may need to be improved to accurately adjust the FEA to improve joint functionality and patient satisfaction.
