研究目的: |
全膝关节置换术(TKA)是一种有效治疗终末期膝关节骨性关节炎的外科方法,可以缓解膝关节疼痛,改善膝关节功能。围术期出血是TKA手术最早期、最常见的并发症之一。但针对高原创伤骨科手术的失血风险因素分析和优化血液管理策略的研究仍存在不足的现状。本研究采用回顾性队列研究,系统对比分析低海拔地区和高海拔地区TKA手术患者围术期失血量的差异以及引起出血差异的独立危险因素,绘制ROC曲线初步推断其适宜高海拔地区TKA手术的截断值,明确出血量差异是否会影响患者术后1年膝关节恢复和并发症发生情况。研究成果将为临床医生实施手术提供充分的理论依据和实践指导,帮助医生评估出血风险、减少术中出血、改善患者预后,提高手术成功率和患者满意度,最终将惠及百万高原藏族同胞。 |

Objectives of Study: |
Total knee arthroplasty (TKA) is an effective surgical method for treating end-stage knee osteoarthritis, which can relieve knee pain and improve knee function. Perioperative bleeding is one of the earliest and most common complications of TKA. However, there is still a lack of research on the risk factors for blood loss in high-risk orthopedic surgeries and the optimization of blood management strategies. This study used a retrospective cohort study to systematically compare the differences in perioperative blood loss between TKA patients in low-altitude and high-altitude areas, as well as the independent risk factors for bleeding differences. The ROC curve was drawn to preliminarily infer the appropriate cutoff value for TKA in high-altitude areas, and to determine whether the difference in blood loss would affect the recovery of the knee joint and the occurrence of complications one year after surgery. The research results will provide sufficient theoretical basis and practical guidance for clinicians to perform surgeries, help doctors assess bleeding risks, reduce intraoperative bleeding, improve patient prognosis, increase the success rate of surgeries and patient satisfaction, and ultimately benefit millions of Tibetan compatriots living in high-altitude areas. |
