文题释义:
关节镜:是一种观察关节内部结构的直径约5 mm的棒状光学器械,是用于医师诊治关节疾患的内窥镜。关节镜在一根细管的端部装有一个透镜,将细管插入关节内部,关节内部的结构便会在监视器上显示出来,因此,可以直接观察到关节内部的结构。
膝关节镜优点:目前膝关节镜手术被认为是对膝关节病变较好的治疗手段。膝关节镜手术具有创伤小、出血少、疗效确切、恢复快、并发症少以及手术瘢痕小等优点。
 
摘要
背景:老年膝关节退行性骨关节炎的治疗主要是以缓解患者疼痛,恢复膝关节功能,提高生活质量,延缓关节置换时间,减少翻修次数为目的。目前此病最常用的治疗方式为膝关节置换,但治疗费用昂贵,手术创伤大,风险高,术后易出现假体松动及周围感染等风险,不良反应较多。
目的:试验设想采用关节镜下病灶清理的保膝疗法治疗老年膝关节退行性骨关节炎,可节省治疗费用,疗效确切,安全可靠。
方法:试验将纳入朝阳市第二医院的老年膝关节退行性骨关节炎患者212例(膝),按患者的病情及意愿分为2组:对照组首先于膝关节腔内注射玻璃酸钠,术后口服非类固醇类抗炎药,辅以常规理疗及股四头肌功能锻炼治疗;关节镜组首先进行膝关节镜下病灶清理,术后治疗方法同对照组,每组106例(膝)。术后随访1周,1个月,3个月,6个月,1年,2年。
结果与讨论:研究的主要结局指标为术后2年膝关节HSS评分等级为优的患者例数百分率,以此拟评价膝关节功能恢复情况;次要结局指标为术前、术后1周、1个月、3个月、6个月、1年膝关节HSS评分等级为优的患者例数百分率;术前、术后1周、1个月、3个月、6个月、1年、2年膝关节HSS评分、目测类比评分、WOMAC骨性关节炎指数评分、膝关节活动度、住院费用及膝关节X射线形态,术后2年治疗费用,术后1周、1个月、3个月、6个月、1年、2年不良反应发生率。试验结果数据反映以关节镜下病灶清理治疗老年膝关节退行性骨关节炎,是否有不良反应少,治疗费用低,能有效恢复患者膝关节功能的3点优势。试验经朝阳市第二医院医学伦理委员会批准(审批单位:辽宁省朝阳市第二医院,审批号:2017-08-01)。研究符合世界医学会制定的《赫尔辛基宣言》的要求。参与者对试验方案和过程均知情同意,并签署知情同意书。试验设计时间为2017年6月,试验于2018年6月至开始进行患者招募及数据收集,2018年12月完成患者招募,2021年6月进行结果指标分析,2021年8月试验完成。文章结果将以科学会议报告,或在同行评议的期刊上发表传播。试验已在中国临床试验注册中心注册(注册号:ChiCTR1800015208),注册方案版本号1.0。

Abstract:

BACKGROUND: The treatment of degenerative knee osteoarthritis is mainly to relieve pain, restore knee function, improve quality of life, delay knee replacement, and reduce the number of revisions. Knee replacement is currently the most common treatment for this disease, but it costs much, has great trauma and high risk, often results in prosthesis loosening and peripheral infection, and has many adverse reactions.

OBJECTIVE: We hypothesize that knee-preserving arthroscopic debridement for treatment of knee degenerative osteoarthritis in the elderly patients costs less, is effective, safe, and reliable.
METHODS:A total of 212 elderly patients (knees) with degenerative knee osteoarthritis who receive treatment in the Second Hospital of Chaoyang (Liaoning Province, China) will be included in this study. These patients will be assigned to two groups according to patient’s conditions and wishes (n = 106/group). In the control group, intra-articular injection of sodium hyaluronate will be performed, followed by oral administration of non-steroidal anti-inflammatory drugs, conventional physiotherapy, and quadriceps functional exercise. In the arthroscopic debridement group, arthroscopic debridement will be performed followed by oral administration of non-steroidal anti-inflammatory drugs, conventional physiotherapy, and quadriceps functional exercise. All patients will be followed up for 1 week, 1 month, 3 months, 6 months, 1 year, and 2 years.
RESULTS AND CONCLUSION: The primary outcome measure is the percentage of the number of patients with Hospital for Special Surgery (HSS) knee score ≥ 85 points at 2 years after surgery, which will be used to evaluate knee function recovery. The secondary outcome measures are the percentage of the number of patients with HSS knee score ≥ 85 points before surgery, 1 week, 1 month, 3 months, 6 months, and 1 year after surgery; HSS score, Visual Analogue Scale (VAS) score, The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), knee range of motion, hospitalization costs, and knee X-ray morphology before surgery, 1 week, 1 month, 3 months, 6 months, 1 year, and 2 years after surgery, medical costs after 2 years of treatment, incidence of adverse reactions at 1 week, 1 month, 3 months, 6 months, 1 year and 2 years after surgery. Findings from this study will reveal whether arthroscopic debridement for the treatment of degenerative knee osteoarthritis in the elderly patients has advantages of less adverse reactions, low treatment costs, and can effectively restore knee function. This trial has been approved by the Second Hospital of Chaoyang, Liaoning Province, China (approval number: 2017-08-01). All protocols will be in accordance with Declaration of Helsinki, formulated by the World Medical Association. Written informed consent will be provided by participants. This trial was designed in June 2017. The recruitment of subjects and data collection will begin in June 2018. The recruitment of subjects will be finished in December 2018. Outcome measures will be analyzed in June 2021. This trial will be completed in August 2021. The results of the trial will be reported in a scientific conference or disseminated in a peer-reviewed journal. This trial had been registered in the Chinese Clinical Trial Registry (registration number: ChiCTR1800015208). The version of this study protocol is (1.0).
