探讨关节镜下半月板成形术治疗老年膝关节半月板损伤的疗效。

选择2019年1月至2020年1月重庆宏仁一医院骨科收治的80例老年膝关节半月板损伤患者作为观察对象。依据手术治疗方案的不同，将患者分为对照组（接受关节镜下半月板切除术治疗）和观察组（接受关节镜下半月板成形术治疗），各40例。比较两组患者手术前后Lysholm膝关节评分、简明健康状况调查量表（SF-36）评分以及术后临床疗效。组间计量资料的比较采用t检验，计数资料的比较采用χ²检验。

手术后，观察组Lysholm膝关节评分和SF-36评分均显著高于对照组，差异均有统计学意义（t=14.228、4.817，P<0.01）。观察组手术治疗的优良率显著高于对照组，差异有统计学意义（χ²=6.542，P<0.01）。

老年膝关节半月板损伤患者接受关节镜下半月板成形术治疗效果显著，有助于患者膝关节活动能力的恢复，值得推广应用。

To investigate the efficacy of arthroscopic meniscinoplasty for elderly patients with knee meniscus injury.

A total of 80 elderly patients with knee meniscus injury treated in the Department of Orthopedics of Chongqing Hongren First Hospital during January 2019 and January 2020 were selected into the study. The patients were divided into control group (treated with arthroscopic meniscectomy) and observation group (treated with arthroscopic meniscinoplasty), with 40 cases in each group. Lysholm scores, clinical efficacy and the MOS item short from health survey (SF-36) scores were compared between the two groups. T test was used to compare measurement data, and chi-square test was used to compare technical data.

After surgery, Lysholm knee score and SF-36 score in the observation group were significantly higher than those in the control group (t=14.228, 4.817, P < 0.01). The excellent and good rate of surgical treatment in the observation group was significantly higher than that in the control group (χ²=6.542, P < 0.01).

Arthroscopic meniscinoplasty has good effect on elderly patients with knee meniscus injury, and is helpful for the recovery of patients’ knee mobility, so is worthy of clinical application.
