分析膝关节半月板损伤手术患者术后疼痛及其影响因素。

将2019年11月至2021年3月海军青岛特勤疗养中心收治的膝关节半月板损伤手术患者150例纳入研究，患者术后均接受规律康复训练治疗。以术后6个月视觉模拟评分表(VAS)得分患者分为疼痛组(n＝23)和非疼痛组(n＝127)。回顾性收集分析膝关节半月板损伤手术患者术后疼痛残留情况，卡方检验和多因素logistic回归分析法分析膝关节半月板损伤手术患者康复训练后疼痛残留的影响因素。

术后6个月，150例膝关节半月板损伤手术患者康复训练后疼痛23例，疼痛残留率为15.3%，疼痛组及非疼痛组患者术后6个月的VAS评分均较术前降低(t＝3.149、20.409，均为P<0.05)；疼痛组与非疼痛组术前VAS评分差异无统计学意义(t＝0.630，P>0.05)；非疼痛组术后6个月VAS评分较疼痛组低(t＝9.961，P<0.05)。年龄>60岁、身体质量指数(BMI)>24 kg/m²、关节软骨损伤、骨关节炎疼痛、行滑膜切除为膝关节半月板损伤患者术后疼痛残留的影响因素[优势比(OR)＝3.130、2.164、2.259、3.881、1.998; 95%置信区间(CI)：(1.537，6.376)、(1.420，3.298)、(1.135，4.495)、(1.376，10.945)、(1.054，3.785)，均为P<0.05]。

膝关节半月板损伤手术患者康复训练后仍有部分遗留疼痛情况，其发生与年龄>60岁、BMI>24 kg/m²、关节软骨损伤、骨关节炎疼痛、行滑膜切除等因素相关。

To analyze the status and influencing factors of postoperative pain residual in patients with knee meniscus injury.

A total of 150 patients with knee meniscus injury who were treated by surgery in Navy Qingdao Special Service Convalescent Center from November 2019 to March 2021 were included in the study. All the patients received regular rehabilitation training after operation. The patients were divided into the pain group (n=23) and the non-pain group (n=127) according to the visual analogue scale (VAS) score six months after the operation. The general data and the status of postoperative residual pain were collected and analyzed. the pain after rehabilitation training was analyzed by chi-square test and the influencing factors of residual pain was analyzed by multivariate logistic regression analysis.

Six months after the operation, 23 of 150 patients with knee meniscus injury had pain after rehabilitation training, and the residual pain rate was 15.3%. There was no statistically significant difference in the preoperative VAS score between the two groups (t=0.630, P>0.05); the postoperative VAS scores were lower than the preoperative ones in the two groups (t=3.149, 20.409, both P<0.05); the postoperative VAS score was higher in the pain group than the non-pain group six months after the operation (t=9.961, P<0.05). Age>60 years old, body mass index(BMI)>24 kg/m², articular cartilage injury, osteoarthritis pain, and synovectomy were the influencing factors for postoperative residual pain in the patients who accepted knee meniscus injury surgery[odds ratio (OR)=3.130, 2.164, 2.259, 3.881, 1.998; 95% confidence interval (CI): (1.537, 6.376), (1.420, 3.298), (1.135, 4.495), (1.376, 10.945), (1.054, 3.785), all P<0.05].

Some patients with knee meniscus injury still have residual pain after rehabilitation training, and the occurrence is related to factors such as age>60 years old, BMI>24 kg/m², articular cartilage injury, osteoarthritis pain, and synovectomy.
