计算机导航下全膝关节置换术治疗膝关节骨关节炎的临床研究

Clinical study of total knee arthroplasty under computer navigation in the treatment of knee osteoarthritis

目的探讨计算机导航下全膝关节置换术(TKA)治疗膝关节骨关节炎的临床效果。方法抽取2019年2月至2021年2月晋城市人民医院收治的86例膝关节骨关节炎患者,依据随机数字表法分为对照组和观察组,每组43例。对照组患者接受常规髓内定位技术下TKA治疗,观察组患者接受计算机导航下TKA治疗。记录并比较两组术中出血量、手术时间;比较两组术前及术后3个月的膝关节活动度、膝关节功能[美国纽约特种外科医院(HSS)膝关节功能评分];记录并比较两组并发症发生情况。结果观察组手术时间[(60.86±3.54)min]短于对照组[(76.71±3.89)min],术中出血量[(116.47±8.49)ml]少于对照组[(147.16±10.57)ml],P<0.05;术后3个月,两组患者膝关节伸直度、屈曲度、HSS膝关节评分均高于术前,且观察组高于对照组(P<0.05);术后两组并发症总发生率比较差异未见统计学意义(P>0.05)。结论计算机导航下TKA治疗膝关节骨关节炎,可减少术中出血量,缩短手术时间,改善膝关节活动度与膝关节功能。

Objective To investigate the clinical effect of total knee arthroplasty(TKA)under computer navigation in the treatment of knee osteoarthritis.Methods Eighty-six patients with knee osteoarthritis treated in Jincheng People’s Hospital from February 2019 to February 2021 were selected,and they were divided into control group and observation group by random number table method,with 43 cases in each group.Patients in the control group were treated by TKA under conventional intramedullary positioning technology,while patients in the observation group were treated by TKA under computer navigation.The amount of intraoperative bleeding and operation time were recorded and compared between the two groups.The knee range of motion and knee function which was evaluated by the knee function score of New York Special Surgery Hospital(HSS)of the two groups were compared before and 3 months after operation.The complications of the two groups were recorded and compared.Results The operation time in the observation group was(60.86±3.54)min,shorter than the(76.71±3.89)min in the control group(P<0.05);and the amount of intraoperative bleeding in the observation group was(116.47±8.49)ml,less than the(147.16±10.57)ml in the control group(P<0.05).Three months after operation,the knee extension,flexion and HSS knee score of the two groups were higher than those before operation,and these indicators of the observation group were higher than those of the control group(P<0.05).There was no significant difference in the total incidence of postoperative complications between the two groups(P>0.05).Conclusions TKA under computer navigation in the treatment of knee osteoarthritis can reduce the amount of intraoperative bleeding,shorten the operation time,and improve their knee range of motion and knee function.
