Study design:

Case study 

研究目的:

1. 评估 3D 打印 PSI 辅助 TKA 治疗血友病合并膝关节强直患者的围手术期安全性,统计手术相关并发症发生情况; 2. 明确该术式对血友病强直膝患者术后下肢力线、膝关节活动度(ROM)的改善效果; 3. 探讨该术式对患者术后膝关节功能、生活质量的短期临床结局的影响,总结其临床应用可行性。  

Objectives of Study:

1. Assess the perioperative safety of 3D-printed PSI-assisted TKA in patients with hemophilia combined with knee joint stiffness, and record the occurrence of surgery-related complications; 2. Clarify the effect of this procedure on improving lower limb alignment and knee joint range of motion (ROM) in patients with hemophilic stiff knees after surgery; 3. Explore the impact of this procedure on short-term clinical outcomes of knee joint function and quality of life in patients after surgery, and summarize its clinical feasibility.
