数字化设计及3D打印技术在人工全膝关节置换术中的应用研究
Application research on digital design and 3D printing technology in total knee arthroplasty
摘要
Abstract
Objective To explore the feasibility and superiority of digital design and 3D printing technology accuracy and clinical efficacy of surgery.Methods80 cases (90 Knees) of patients undergoing primary total knee arthroplasty were randomly divided into ditital group (digital design and 3D printing group) and traditional group. 40 (46 knees) cases were divided into digital group and applied of digital design and 3D printing technology to guide surgery. 40 (44 knees) cases were divided into traditional group and operated by by traditional experience. Incision length, operation time, the amount of bleeding during operation of the two groups were recorded. The matching degree between the prosthesis and the preoperative design was observed. Functional activity of knee joint after operation was evaluated. The changes of the lower limb force line after the imaging examination was compared. Pain visual analogue scale (VAS), American Knee Society rating criteria score (KSS) and patellofemoral joint Feller score at 3 months and 6 months after operation were respectively followed up and compared.ResultsCompared with the traditional group, the length of incision, operation time and blood loss of digital group were better than those of traditional group. There were statistical significances on prosthesis matching degree, joint mobility, lower limb force line correction and VAS, KSS, Feller score (P<0.05). ConclusionDigital design and 3D printing technology can well guide the initial total knee replacement. It is benefit to improve the accuracy and short-term clinical efficacy of surgery.关键词
