研究目的:

(1)通过前瞻性、平行随机对照研究的方法,比较 3D 打印 PSI 辅助 TKA 与传统 TKA在临床结果上的差异。包括手术时间、术后疼痛和止疼药用量、术后出血和输血情况、术后力线和功能恢复情况等。 (2)通过前瞻性研究,评估 3D 打印 PSI 辅助 TKA 与传统 TKA 的经济学成本。包括住院费用、患者和/或家人工作岗位上收入的损失、出院后康复费用、聘请看护人员的费用等。 (3)结合上述两项结果,通过成本-效果、成本-效益和成本-效用分析,评价 3D 打印 PSI 技术在 TKA 临床应用中的卫生经济学价值,为其在关节置换手术中的开展和推广提供决策证据。  

Objectives of Study:

1. To compare the clinical outcomes of 3D-printed patient-specific instrumentation (PSI)-assisted total knee arthroplasty (TKA) and conventional TKA through a prospective, parallel, randomized controlled study. This includes parameters such as operative time, postoperative pain and analgesic use, postoperative bleeding and transfusion needs, and postoperative alignment and functional recovery. 2. To evaluate the economic costs of 3D-printed PSI-assisted TKA versus conventional TKA through a prospective study. This includes hospitalization expenses, loss of income for patients and/or their family members due to work absence, post-discharge rehabilitation costs, and caregiver expenses. 3. To assess the health economic value of 3D-printed PSI in TKA clinical practice by integrating the above findings through cost-effectiveness, cost-benefit, and cost-utility analyses. This aims to provide evidence-based support for the adoption and promotion of PSI technology in joint replacement surgery.

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data Collection and Management Plan 1. Data Collection Data will be collected using electronic systems (e.g., REDCap) to ensure accuracy and integrity. After participants provide informed consent to participate, data will be collected according to the study protocol. The data collected will include demographic information, clinical diagnosis, treatment plans, and postoperative recovery. 2. Data Management The storage, processing, and analysis of data will follow strict management procedures. All data will be stored in an encrypted database with access control, limited to authorized research personnel. Data will be regularly backed up to prevent data loss. 3. Data Quality Control During the data collection process, regular quality checks will be conducted to ensure the completeness, accuracy, and consistency of the data. Any errors or missing data will be promptly corrected, and records will be maintained. Research personnel will also receive regular training to ensure consistency in data collection and management. 4. Data Sharing and Confidentiality After the study, data will be shared with other researchers, in compliance with ethical guidelines and relevant policies, while ensuring participant privacy and confidentiality. All shared data will be de-identified to protect participant identities.
