Objective To explore the clinical effect of arthroscope-assisted surgical treatment with plasma blade and conventional apparatus for knee meniscus injury. Methods 135 military patients with meniscus injury were selected and divided into plasma blade group(n=77) and conventional apparatus group(n= 58) according to the operation method. The Lysholm scores, recovery periods and the incidence of joint effusion after operation of patients from two groups were compared respectively. Results The mean follow-up period was 15 months,and symptoms of patients in two groups disappeared after operation. Compared with the conventional apparatus group,postoperative recovery time of patients in plasma blade group was markedly reduced,their incidence rate of joint effusion was significantly decreased, and their Lysholm scores were markedly higher 15 days after operation(P<0. 05). There was no statistically significance in Lysholm scores between two groups 3 months after operation (P>0. 05). Conclusion It is feasible for arthroscope-assist surgery using plasma blade to treat knee meniscus injury, which is worth promoting for clinical use.%目的 探讨关节镜下等离子刀与常规器械手术治疗膝半月板损伤的临床效果.方法 选择135例半月板损伤的部队患者,按手术方式将其分为等离子刀组(n=77)及常规器械组(n=58).术后分别比较两组患者Lysholm评分、术后康复时间及关节积液发生情况.术后平均随访15个月.结果 两组患者术后症状消失,等离子刀组康复时间较常规器械组明显缩短,关节积液发生率明显减少,术后15 d Lysholm评分显著优于同期的常规器械组(P<0.05),术后3个月两组患者Lysholm评分差异无统计学意义(P>0.05).结论 关节镜下采用等离子刀治疗膝半月板损伤是可行的,值得推广应用.
