膝关节镜技术对于膝关节单髁置换手术的疗效影响探究

Study on the Effect of Knee Arthroscopy on Knee Condyle Replacement

目的:探讨膝关节镜技术对于膝关节单髁置换手术疗效的影响.方法:选取本院收治的50例膝关节单间室关节炎患者,随机分为2组,各25例,对照组采用单纯单髁置换术(UKA)治疗,观察组采用膝关节镜检+UKA治疗,比较2组手术前后疼痛VAS和HSS评分、术后直腿抬高和主动屈曲到90°所用的时间、膝关节活动度及并发症情况.所有患者均获得12个月的随访.结果:手术后12个月VAS评分和HSS评分:观察组分别为(2.42±0.83)分和(82.45±6.91)分,对照组分别为(2.35±0.85)分和(82.31±6.87)分,2组各项评分均较术前明显改善(P<0.05),组间比较无显著差异(P>0.05).观察组直腿抬高到90°的时间(3.23±0.82)天和主动屈曲到90°的时间(4.05±1.35)天,短于对照组的(3.71±0.93)天和(4.71±1.05)天(P<0.05).膝关节活动度:术后1、3个月2组患者膝关节活动度比较无显著差异(P>0.05),术后6、12个月膝关节活动度观察组均明显优于对照组(P<0.05).术后2组未见感染、假体松动、血栓、皮肤坏死等并发症事件发生.结论:在单髁置换术中应用膝关节镜检查对治疗膝关节单间室关节炎效果优于对照组,值得临床应用推广.

Objective:To investigate the effect of knee arthroscopy on the outcome of knee joint replacement surgery.Methods:Fifty patients with knee joint single compartment arthritis admitted to our hospital were randomly divided into two groups,25 patients in the control group.The control group was treated with simple sputum replacement(UKA),and the observation group was treated with knee arthroscopy+UKA.The pain VAS and HSS scores before and after surgery,the time of postoperative straight leg elevation and active flexion to 90°,knee joint mobility and complications were compared.All patients were followed for 12 months.Results:VAS score and HSS score at 12 months after surgery:(2.42±0.83)points and(82.45±6.91)points in the observation group and(2.35±0.85)points and(82.31±6.87)points in the control group,respectively.The scores of the group were significantly improved compared with the preoperative(P<0.05),and there was no significant difference between the groups(P>0.05).The time during which the straight leg was raised to 90°(3.23±0.82)d and the time during active flexion to 90°(4.05±1.35)d was shorter than that of the control group(3.71±0.93)d and(4.71±1.05)d(P<0.05).Knee activity:There was no significant difference in knee joint activity between the two groups at 1 and 3 months after operation(P>0.05).The knee joint activity observation group was significantly better than the control group at 6 and 12 months after operation.(P<0.05).No complications such as infection,loosening of the prosthesis,thrombosis,and skin necrosis occurred in the two groups.Conclusion:The application of knee arthroscopy in the treatment of knee joint single compartment arthritis is better than the control group in single iliac replacement surgery,which is worthy of clinical application.
