骨岛技术在后交叉韧带保留型膝关节置换中的应用效果

Application effect of bone island technique in posterior cruciate ligament preserving knee arthroplasty

目的探讨骨岛技术在后交叉韧带保留型膝关节置换中的应用效果。方法选取2019年11月至2020年3月中山市中医院关节科收治的120例膝关节骨性关节炎患者作为研究对象,采用随机数字法分为后稳定型假体(PS)组、传统截骨后交叉韧带保留型(CR)假体组以及骨岛截骨CR假体组,每组40例。比较三组的美国特种外科医院膝关节评分(HSS)评分、视觉模拟评分法(VAS)评分、股骨髁后滚程度、膝关节活动度。结果术后1个月,骨岛截骨CR假体组HSS评分高于CR假体组、PS组,CR假体组HSS评分高于PS组,差异有统计学意义(P<0.05)。术后1个月,三组VAS评分比较,差异无统计学意义(P>0.05)。术后1个月,三组的股骨髁后滚距离、膝关节活动度比较,差异无统计学意义(P>0.05)。结论三种方式治疗膝关节骨性关节炎,其术后疼痛程度、膝关节活动度、股骨髁后滚程度相当,但骨岛截骨CR假体的膝关节功能更佳,临床值得推广。

Objective To study the application effect of bone island technique in posterior cruciate ligament preserving knee arthroplasty.Methods A total of 120 patients with knee osteoarthritis admitted to the Department of Arthrosis,Zhongshan Hospital of Traditional Chinese Medicine from November 2019 to March 2020 were selected as the research subjects.The patients were divided into stable prosthesis(PS)group,traditional posterior cruciate ligament(CR)prosthesis group and bone island osteotomy CR prosthesis group accordin to the random number table method,with 40 patients in each group.Hospital for special surgery knee(HSS)score,visual analogue scale(VAS)score,femoral condyle retrorolling degree and knee motion were compared among the three groups.Results One month after surgery,HSS score of bone island osteotomy CR prosthesis group was higher than that of CR prosthesis group and PS group,and HSS score of CR prosthesis group was higher than that of PS group,the differences were statistically significant(P<0.05).One month after surgery,there was no significant difference in VAS scores among the three groups(P>0.05).One month after surgery,there were no significant differences in femoral condyle retrorolling distance and knee motion among the three groups(P>0.05).Conclusion The three methods for the treatment of knee osteoarthritis have the same degree of postoperative pain,knee range of motion and femoral condyle roll back,but knee function of bone island osteotomy CR prosthesis is better,clinical worthy of promotion.
