The postoperative pain associated with total knee arthroplasty (TKA) is severe for most patients. The analgesic efficacy and safety of preoperative use of selective cyclooxygenase-2 (COX-2) inhibitors for patients undergoing TKA are unclear.
We conducted a systematic review and meta-analysis to assess whether the use of selective COX-2 inhibitors before TKA decreases the postoperative pain intensity.
Data sources: The PubMed, Embase, EBSCO, Web of Science, and Cochrane Controlled Register of Trials databases from inception to January 2020.
All randomized controlled trials (RCTs) in which the intervention treatment was preoperative selective COX-2 vs placebo in patients undergoing TKA and that had at least one of the quantitative outcomes mentioned in the following section of this paper were included. Letters, review articles, case reports, editorials, animal experimental studies, and retrospective studies were excluded.
All RCTs in which the intervention treatment was preoperative selective COX-2 vs placebo in patients undergoing TKA.
The quality of the RCTs was quantified using the Newcastle-Ottawa quality assessment scale. RevMan 5.3 software was used for the meta-analysis.
Six RCTs that had enrolled a total of 574 patients were included in the meta-analysis. The visual analog scale pain score at rest was significantly different between the experimental group and control group at 24 hours (P < .05) and 72 hours (P < .05) postoperatively. The experimental group exhibited a significant visual analog scale pain score during flexion at 24 hours postoperatively (P < .05), and it was not different at 72 hours postoperatively (P = .08). There was a significant difference in opioid consumption (P < .05), but there was no difference in the operation time (P = .24) or postoperative nausea/vomiting (P = .64) between the groups.
The efficacy of preoperative administration of selective COX-2 inhibitors to reduce postoperative pain and opioid consumption after TKA is validated.

全膝关节置换术（TKA）后疼痛剧烈，大多数患者均如此。对于接受 TKA 的患者，术前使用选择性环氧化酶-2（COX-2）抑制剂的镇痛效果和安全性尚不清楚。
我们进行了一项系统评价和荟萃分析，以评估 TKA 术前使用选择性 COX-2 抑制剂是否能降低术后疼痛强度。
数据来源：从建库至 2020 年 1 月，检索 PubMed、Embase、EBSCO、Web of Science 和 Cochrane 对照试验注册库。
所有干预措施为 TKA 术前选择性 COX-2 与安慰剂比较的随机对照试验（RCT），且至少有以下部分中提到的定量结局之一。排除信件、综述文章、病例报告、社论、动物实验研究和回顾性研究。
所有 TKA 术前选择性 COX-2 与安慰剂比较的 RCT。
采用纽卡斯尔-渥太华质量评估量表对 RCT 质量进行量化。使用 RevMan 5.3 软件进行荟萃分析。
共纳入 6 项 RCT，总计 574 例患者。术后 24 小时（P<0.05）和 72 小时（P<0.05）时，实验组与对照组静息时视觉模拟评分疼痛明显不同。术后 24 小时时，实验组在膝关节弯曲时的视觉模拟评分疼痛明显（P<0.05），但在术后 72 小时时无差异（P=0.08）。两组间阿片类药物用量（P<0.05）差异显著，但手术时间（P=0.24）或术后恶心/呕吐（P=0.64）无差异。
术前使用选择性 COX-2 抑制剂可有效减轻 TKA 后疼痛和阿片类药物的使用。
