三维数字化测量辅助全膝关节置换术治疗重度膝骨关节炎
Three-dimensional digital measurement assisted total knee arthroplasty in the treatment of se-vere knee osteoarthritis
摘要
Abstract
Objective To investigate the application effect of three-dimensional(3D)digital measurement of lower limb related angle of severe knee osteoarthritis patients in total knee arthroplasty(TKA).Methods The 80 patients with severe knee osteoarthritis were divided into X-ray measurement group(traditional TKA treatment,40 cases)and 3D digital measurement group(3D digital measurement assissted TKA treatment,40 cases)according to random num-ber table method.The difference of the lower limb alignment related angle measured before surgery,operation situa-tion,HSS score at 3 months after surgery and knee activity were compared between the two groups.Results Both groups were followed up for 3～6 months.The hip-knee-ankle angle,femorotibial angle,tibial angle in X-ray measure-ment group were larger than those in 3D digital measurement group(P<0.05),and there were no statistical differ-ences in the posterior slope angle of tibial plateau,femur angle and femoral valgus angle between the two groups(P>0.05).Operation time,intraoperative blood loss and postoperative drainage volume were all longer(more)in X-ray measurement group than those in 3D digital measurement group(P<0.05).At 3 months after surgery,HSS scores:Two groups were higher that before surgery(P<0.05),and there was no statistical difference between the two groups(P>0.05).The knee flexion activity:At 3 months after surgery,both groups was higher than that before surgery(P<0.05),and 3D digital measurement group was larger than that in the X-ray measurement group(P<0.05).Conclusions Compared with X-ray measurement,3D digital measurement of lower extremity related angle in patients with severe knee osteoarthritis is more accurate,assisted TKA treatment has shorter operation time,less intraoperative blood loss and postoperative drainage volume,and more satisfactory postoperative knee activity.关键词
