摘要
目的比较计算机导航辅助与传统方法行人工膝关节置换术(TKA)的近期疗效,探讨计算机导航辅助应用于TKA的优势。方法将186例行TKA的骨关节炎患者(186膝)分为导航组(110膝)和非导航组(76膝)。比较两组的手术时间、切口长度、术后总引流量、术后下肢力线、术后KSS关节功能评分以及WOMAC评分。结果 186例患者均获得随访,时间12个月。与非导航组相比,导航组手术时间平均延长9 min,手术切口平均长了2 cm,但术后引流量更少,下肢力线偏离≥3°更少,胫骨平台后倾更接近预设值0°;以上各项指标两组比较差异均有统计学意义(P <0. 05)。术后KSS关节功能评分和WOMAC评分导航组均优于非导航组(P <0. 05)。结论计算机导航辅助TKA能提高下肢力线的精准度,提高膝关节假体安放的准确性,近期临床效果较传统手术更有优势。
Objective To compare the short-term therapeutic effects of computer-aided navigation and conventional methods for total knee arthroplasty（TKA）, and investigate the application advantages of computer-aided navigation in TKA. Methods The 186 patients （186 knees）with osteoarthritis who were initially treated with TKA were divided into the navigation group （110 knees） and non-navigation group （76 knees）. The operative time, incision length, postoperative total drainage volume, postoperative limb alignment, postoperative KSS joint function score, and WOMAC score were compared between the two groups. Results All patients were followed up for 12 months. Compared with the non-navigation group, the operation time of the navigation group was extended by an average of 9 min, the average length of the incision was lengthened 2 cm; however there were less postoperative drainage volume,the limb alignment deviation ≥3° was less, the tibial plateau leans was closer to the preset value of 0°; the postoperative KSS joint function score and WOMAC score were better in the navigation group,the above indicators were statistically significant （ P 〈0.05）. Conclusions Computer-aided navigation TKA can improve the precision of the lower limb alignment and improve the accuracy of the placement of the knee prosthesis, the recent clinical effects are more advantageous than conventional surgery.
