Augmented reality and mixed reality have been used to help surgeons perform complex surgeries. With the development of technology, mixed reality (MR) technology has been used to improve the success rate of complex hip arthroplasty due to its unique advantages. At present, there are few reports on the application of MR technology in total knee arthroplasty. We presented a case of total knee arthroplasty with the help of mixed reality technology.
We presented a case of a 71-year-old woman who was diagnosed with bilateral knee osteoarthritis with varus deformity, especially on the right side. After admission, the right total knee arthroplasty was performed with the assistance of MR technology. Before the operation, the three-dimensional virtual model of the knee joint of the patient was reconstructed for condition analysis, operation plan formulation, and operation simulation. During the operation, the three-dimensional virtual images of the femur and tibia coincided with the real body of the patient, showing the osteotomy plane designed before the operation, which can accurately guide the completion of osteotomy and prosthesis implantation.
As far as we know, this is the first report on total knee arthroplasty under the guidance of mixed reality technology.
增强现实和混合现实已被用于帮助外科医生进行复杂手术。随着技术的发展，混合现实（MR）技术因其独特优势已被用于提高复杂髋关节置换术的成功率。目前，关于MR技术在全膝关节置换术中应用的报道较少。我们展示了一例在混合现实技术帮助下进行全膝关节置换术的病例。
我们展示了一例71岁女性患者，她被诊断为双侧膝关节骨关节炎伴内翻畸形，尤其是右侧。入院后，在MR技术辅助下进行了右侧全膝关节置换术。术前，重建了患者膝关节的三维虚拟模型，用于病情分析、手术方案制定和手术模拟。术中，股骨和胫骨的三维虚拟图像与患者真实身体重合，显示了术前设计的截骨平面，可准确指导截骨和假体植入的完成。
据我们所知，这是关于在混合现实技术引导下进行全膝关节置换术的首次报道。
