Study design:

Cohort study 

研究目的:

本研究拟纳入拟行全膝关节置换术的膝骨关节炎患者,术前采集粪便样本,开展16S rRNA测序和拉曼光谱检测,提取肠道菌群特征、拉曼光谱特征及临床特征,随访术后慢性疼痛发生情况,构建并验证基于多组学特征的机器学习预测模型,以评估其对全膝关节置换术后慢性疼痛的预测价值,为术后慢性疼痛的早期风险识别和个体化干预提供依据。  

Objectives of Study:

This study aims to enroll patients with knee osteoarthritis scheduled for total knee arthroplasty. Preoperative fecal samples will be collected for 16S rRNA sequencing and Raman spectroscopy. Gut microbiota features, Raman spectral features, and clinical variables will be extracted. The occurrence of chronic pain after total knee arthroplasty will be followed up. A machine learning prediction model based on multi-omics features will be developed and validated to evaluate its predictive value for chronic pain after total knee arthroplasty, providing evidence for early risk identification and individualized management.

药物成份或治疗方案详述:

本研究为观察性前瞻性队列研究,不设置额外药物或治疗干预措施。所有受试者均按照临床常规接受全膝关节置换术及围术期管理。研究流程包括:术前采集受试者粪便样本,进行16S rRNA测序和拉曼光谱检测;同时收集人口学资料、临床资料、术前疼痛评分、功能评分、合并症、围术期相关指标等信息;术后按照研究方案进行随访,记录慢性疼痛发生情况及相关结局指标。研究所得16S rRNA测序特征、拉曼光谱特征及临床特征将用于构建和验证机器学习预测模型,以预测全膝关节置换术后慢性疼痛发生风险。 

Description for medicine or protocol of treatment in detail:

This is an observational prospective cohort study without additional drug or therapeutic intervention. All participants will receive routine total knee arthroplasty and standard perioperative management according to clinical practice. The study procedures include preoperative collection of fecal samples for 16S rRNA sequencing and Raman spectroscopy, as well as collection of demographic data, clinical characteristics, preoperative pain scores, functional scores, comorbidities, and perioperative variables. Postoperative follow-up will be conducted according to the study protocol to assess the occurrence of chronic pain and related outcomes. Features derived from 16S rRNA sequencing, Raman spectroscopy, and clinical variables will be used to develop and validate a machine learning prediction model for chronic pain after total knee arthroplasty.
