Filter by:This prospective observational study aims to collect and analyse data on functional outcomes, quality of life indicators, and costs in patients undergoing primary total knee arthroplasty (knee replacement) surgery.
The project intends to analyze the epidemiological characteristics, risk factors, complications and resource utilization of artificial joint replacement in China through the inpatient data collected by the Hospital Quality Monitoring System (HQMS). The HQMS database is a mandatory electronic inpatient database system developed by the National Health Commission of the People's Republic of China. Since 2013, tertiary hospitals have been required to upload their inpatient discharge records. By 2019, the HQMS database has included more than 230 million standardized inpatient discharge records of over 1000 hospitals across all 31 provincial-level administrative regions in mainland China. Patient demographics, clinical diagnosis, procedures and operations, drug use, costs and complications were all recorded in the HQMS database. The investigators planned to include five types of arthroplasty, including knee arthroplasty, hip arthroplasty, shoulder arthroplasty, ankle arthroplasty and elbow arthroplasty. The data analysis will be conformed to the principle of confidentiality and will not reveal the privacy of those patients. The data will be only used for this research project and there is no conflict of interest. It is in line with the principles of ethics, harmlessness and fairness. This study was authorized by the HQMS Committee Board and approved by the institutional review board, with waiver of informed consent.
The purpose of the study is the evaluation of the clinical and radiological long-term performance of the balanSys UNI fix in a multicenter routine clinical setting.
The mobile bearing unicompartmental knee arthroplasty has shown excellent clinical outcome and survivorship. However, some studies have shown that the patients still had medial knee pain and shown worst the clinical outcome, even though the survivorship was excellent. The medial knee pain after operation was the one cause of revision. The incidence of medial knee pain was 0%-9%. The cause of medial knee pain was overloading on the medial plateau, local inflammation, over hanging of the tibial component and overstretching of the MCL due to the application of excessive polyethylene. Therefore, the tibia in this study was cut with under resection technique for reducing the overloading on the medial tibial plateau. The purpose of this study is to compare medial knee pain between tibial bone cut preservation technique and conventional tibial bone cut technique following mobile bearing UKA.
Total knee arthroplasty (TKA) may result in significant postoperative pain. The majority of these patients are prescribed opioids for the management of postoperative pain. Recent evidence has highlighted that postoperative opioids are being over-prescribed resulting in opioid misuse and abuse. Over-prescribing also results in a significant financial cost. This prospective observational study was designed to determine the mean amount of opioid required after TKA. This data can be used in the future as a guide to change our current practice of prescribing with the aim to reduce over-prescription.
