研究目的: |
1. 主要目的:采用 Avizo 软件结合 MAR-CT 进行 3D 量化分析,对比全膝关节置换术(TKA)中 “仅骨面覆盖骨水泥 + 骨锤敲击” 与 “骨面 + 假体面覆盖骨水泥” 两种技术,在骨水泥渗透深度、界面接触面积占比、界面间隙宽度及分布均匀度等核心黏合指标上的差异,明确两种技术对假体 - 骨界面黏合效果的影响。 2. 次要目的:记录并分析两组术中骨水泥实际用量、操作时长及术后不良事件(感染、出血、深静脉血栓等)发生率,评估两种技术的安全性、经济性及临床可行性。对比两组患者术前及术后的临床功能恢复情况,包括 KSS 评分(疼痛、功能、活动度子项)、WOMAC 指数(疼痛、僵硬、功能子项)及 VAS 疼痛评分(静息 + 活动时),明确技术差异对患者术后生活质量的影响。 |

|
Objectives of Study: |
1. Primary Objective: Employ Avizo software in conjunction with MAR-CT for 3D quantitative analysis, to compare two techniques in total knee arthroplasty (TKA): "bone-surface-only cemented with bone hammering" versus "bone-surface-plus-prosthesis-surface cemented." The study evaluates differences in core cement-bonding metrics—cement penetration depth, proportion of interfacial contact area, interfacial gap width, and distribution uniformity—to clarify the impact of these techniques on prosthesis-bone interface bonding efficacy. 2. Secondary Objectives: Document and analyze actual intraoperative bone cement usage, procedure duration, and postoperative adverse event rates (infection, bleeding, deep vein thrombosis, etc.) across both groups to evaluate the safety, cost-effectiveness, and clinical feasibility of each technique. Compare preoperative and postoperative clinical functional recovery between patient groups, including KSS scores (pain, function, range of motion), WOMAC index (pain, stiffness, function), and VAS pain scores (at rest and during activity), to clarify the impact of technical differences on postoperative quality of life. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
本研究采用电子数据采集(EDC)系统进行研究数据的采集与管理;相关人员通过接受培训后,获取相应权限账号可登录EDC系统,按照试验方案要求,将数据录入EDC中。EDC系统自动核查录入的数据并产生相应提示信息,允许研究人员对录入的数据进行修改,最后主要研究者或其授权的研究人员进行电子签名。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
In this study, electronic data acquisition (EDC) system is used to collect and manage research data. After receiving the training, the relevant personnel can obtain the corresponding permission account to log in to the EDC system, and enter the data into the EDC according to the requirements of the test plan. The EDC system automatically checks the input data and generates corresponding prompts, allowing the researcher to make changes to the input data, and finally the principal investigator or his authorized researcher to sign electronically. |
