摘要
目的通过比较不同方法指导人工全膝关节置换术对手术精确性及临床疗效的影响,探讨数字化设计及3D打印技术在人工全膝关节置换术中应用的可行性、优越性。方法 80例(90膝)行初次人工全膝关节置换术患者被随机分为数字化组(数字化设计及3D打印组)和传统组。数字化组40例(46膝),应用数字化设计及3D打印技术指导手术;传统组40例(44膝),按传统经验进行手术。分别记录两组切口长度、手术时间、术中出血量,观察术中假体与术前设计的匹配度,评价术后患者膝关节功能活动情况,复查影像学比较术后下肢力线变化。术后3个月、6个月分别随访对比观察疼痛视觉模拟评分(VAS)、美国膝关节协会评定标准评分(KSS)和髌股关节Feller评分。结果数字化组在切口长度、手术时间、术中出血量方面较传统组有优势,假体匹配度、关节活动度、下肢力线纠正和VAS、KSS、Feller评分方面与传统组相比差异有统计学意义(P<0.05)。结论数字化设计及3D打印技术能良好指导初次人工全膝关节置换术,有助于提高手术精确性及短期的临床疗效。
