中文摘要:
目的:探讨造成人工全膝关节置换术(total knee arthroplasty,TKA)后矢状面上股骨假体不同位置放置的原因.
方法:回顾性的收集2012年2月1日至2014年2月1日之间,因膝关节骨性关节炎入院,且由同一主刀行初次人工全膝关节置换术患者共251例作为研究对象.根据术后全长片矢状面股骨假体屈曲角(femoral prosthesis flexion angle,FPFA)分为3组:FPFA>3°为屈曲组共68例,其中男18例,女50例,平均年龄(68.59±6.16)岁;0°~3°为中立组共143例,其中男33例,女110例,平均年龄(69.26±6.74)岁;<0°为过伸组共40例,其中男8例,女32例,平均年龄(70.31±6.70)岁.观察并记录各组研究对象的身高、性别、体重指数(body mass index,BMI)、股骨长度、股骨前弓角度及术中股骨远端切除厚度等资料,并做统计学分析.
结果:屈曲组、中立组及过伸组的FPFA分别为(4.48±1.52)°、(1.93±0.57)°、(-1.52±0.43)°,差异有统计学意义(P<0.05);各观察指标中股骨前弓角、身高、股骨长度各自在3组之间差异均有统计学意义(P<0.05);FPFA与股骨前弓角、身高、股骨长度的回归系数分别为0.605、0.164、0.390.
结论:股骨前弓角度大、股骨长度短、身高矮均会造成术后股骨假体的过伸位放置,其中股骨前弓角度影响最大. |

| Influencing factors on sagittal position of femoral prosthesis after total knee arthroplasty |

ABSTRACT
Objective:To investigate factors of influence sagittal position of femoral prostheses after total knee arthroplasty (TKA).
Methods:From February 1st 2012 to February 1st 2014,251 patients with knee osteoarthritis underwent primary TKA by the same experienced surgeon in our hospital were reviewed. All the cases were divided into 3 groups according to the femoral prosthesis flexion angle(FPFA) on the sagittal plane:FPFA>3° as flexion group,which contained 68 cases,including 18 males and 50 females,with an average age of(68.59±6.16) years old;FPFA between 0° and 3° as neutral group,which contained 143 cases,including 33 males and 110 females,with an average age of(69.26±6.74) years old; While FPFA<0° as extension group,which contained 40 cases,including 8 males and 32 females,with an average age of (70.31±6.70) years old. Indexes including age,gender,height,body mass index(BMI),femoral length,femoral bowing angle and distal femoral resection thickness were observed and recorded. A value of P<0.05 was considered statistically significant.
Results:The FPFA in flexion group,neutral group and extension group were (4.48±1.52)°,(1.93±0.57)°,(-1.52±0.43)° respectively,there was statistical significance among them (P<0.05). Femoral bowing,height and femoral length were statistically significant among 3 group(P<0.05). And the regression coefficient between FPFA and femoral bowing,femoral length and height were 0.605,0.164,0.390 respectively.
Conclusion:Large femoral bowing angle,short femoral length and short height all can lead to the extension of femoral prosthesis,among which femoral bowing has a greatest effect. |
