骨盆正中体位双下肢全长摄影在全膝关节置换术中的应用价值研究

Study on the Application Value of Full-Length Photography of Both Lower Limbs Under Pelvic Median Position i Knee Arthroplasty

目的分析骨盆正中体位双下肢全长摄影在全膝关节置换术中的应用价值。方法92例行全膝关节置换术的患者均拍摄骨盆正中体位及髌骨正中体位的双下肢全长图像,比较两种体位下的测量结果,比较手术前后的膝关节功能。结果骨盆正中位下患者的mMPTA、mLDFA、FBA均大于髌骨正中位(P<0.05);两种体位下的mFTA比较,差异无统计学意义(P>0.05)。术后,患者的膝关节活动度、屈曲畸形、稳定性、疼痛、功能评分均高于术前(P<0.05)。结论骨盆正中体位双下肢全长摄影在全膝关节置换术中具有较高的临床应用价值,能够有效获得准确的下肢力线相关数据,利于促进患者术后膝关节功能恢复。

Objective To analyze the application value of full-length photography of both lower limbs under pelvic median position in total knee arthroplasty.Methods The full-length images of both lower limbs of 92 patients with total knee arthroplasty were taken under pelvic median position and patella median position,and the measurement results of the two positions were compared.The knee joint function before and after surgery was compared.Results The mMPTA,mLDFA and FBA of patients under pelvic median position were higher than those of patients under patella median position(P<0.05);No significant difference was found in mFTA between the two positions(P>0.05).After surgery,the scores of knee joint mobility,flexion deformity,stability,pain and function were higher than those before surgery(P<0.05).Conclusions Full-length photography of both lower limbs under pelvic median position has high clinical application value in total knee arthroplasty,which can effectively obtain accurate data related to the lower limb force line,and is conducive to promoting the recovery of knee joint function after surgery.
