[目的]探究全膝关节置换术后患者踝疼痛与下肢影像学参数的关系.[方法]2023年9月-2024年2月,膝关节骨性关节炎行初次TKA的41例患者纳入本研究.观察术后6个月踝疼痛的发生情况,测量下肢影像参数,分析是否踝疼痛与影像参数的关系.[结果]41例患者中,术后6个月出现踝关节疼痛13例,占31.7％;无踝关节疼痛28例,占68.3％.术前,疼痛组HKA、TAA、TTA和TI显著大于无疼痛组(P＜0.05);术后6个月,疼痛组TAA、TTA、TI和mLDTA显著大于无痛组患者(P＜0.05).两组间术前及术后6个月的ADTA和HAA的差异均无统计学意义(P＞0.05).ROC分析结果表明,⊿HKA和⊿mLDTA预测术后踝关节疼痛的的曲线下面积(area under cure,AUC)值分别为0.893和0.955.[结论]膝关节内翻纠正过大及踝关节代偿不足,可能与膝关节置换术后患者踝关节疼痛有关.
[Objective]To explore the relationship between ankle pain and imaging parameters of lower extremity after total knee ar-throplasty.[Methods]From September 2023 to February 2024,41 patients who underwent primary TKA for knee osteoarthritis were en-rolled in this study.The incidence of ankle pain 6 months after operation was observed,the imaging parameters of lower limbs were mea-sured,and the relationship between ankle pain and imaging parameters was analyzed.[Results]Of the 41 patients,13(31.7％)had ankle joint pain 6 months after operation,whereas other 28(68.3％)had no ankle pain.The pain group proved significantly greater HKA,TAA,TTA and TI than the painless group before surgery(P＜0.05),significantly greater TAA,TTA,TI and mLDTA than the painless group 6 months postoperatively(P＜0.05).However,there were no significant differences in ADTA and HAA between the two groups before opera-tion and 6 months after surgery(P＞0.05).As results of ROC analysis,the area under curve(AUC)of ⊿HKA and ⊿mLDTA were 0.893 and 0.955 in predicting postoperative ankle pain respectively.[Conclusion]Over-corrected knee varus and under-compensated ankle may be related to ankle pain after total knee arthroplasty.
