Knee Joint

Knee Joint

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

开发和验证深层卷积神经网络,特别是基于视觉变压器的模型,用于预测膝盖OA的进展.
通过基线膝盖放射和临床数据来评估模型的性能.
评估模型识别可能进展并需要手术干预的患者的能力.

主要方法:

在骨关节炎倡议 (OAI) 数据集中的5565张膝盖放射图上训练了一种视觉转换器模型.
该模型使用了基线图像和临床数据 (完整或基本因素,单个或配对图像).
对远东纪念医院的274例病例进行了外部验证,评估了AUROC,准确性,敏感性和特异性等指标.

主要成果:

该模型在OAI测试中实现了0.808的AUROC,用于OAI进展预测 (最简单的输入:单个图像与基本因素).
外部验证显示,OA进展的AUROC为0.709.
该模型显示出强大的预测能力来识别手术候选人,在OAI中赔率比率为23.87,在外部验证中为5.92.

结论:

开发的视力变压器模型提供了可靠和高效的膝盖OA进展预测.
该模型的简单性和灵活性提高了其临床适用性.
这种人工智能工具有可能显著改善OA患者的早期干预策略.
