研究目的:

通过测量后交叉韧带胫骨止点骨块HU值及韧带HU值,探讨骨组织质量与韧带组织CT衰减特征对后交叉韧带不同损伤模式形成的影响,旨在建立一种基于CT定量参数的损伤模式评估方法,为后交叉韧带损伤的影像学分型、损伤机制分析及临床诊疗决策提供客观依据。  

Objectives of Study:

By measuring the Hounsfield unit values of the tibial insertion bone fragment of the posterior cruciate ligament and the ligament itself, this study aims to investigate the effects of bone tissue quality and ligament tissue CT attenuation characteristics on the formation of different injury patterns of the posterior cruciate ligament. The objective is to establish a CT quantitative parameter-based method for assessing injury patterns, thereby providing objective evidence for imaging classification, injury mechanism analysis, and clinical decision-making in posterior cruciate ligament injuries.

纳入标准:

Inclusion criteria

排除标准:

1. 陈旧性 PCL 损伤、受伤时间不明或受伤至影像检查时间>6 周者。 2. 既往同侧膝关节手术史或既往明确 PCL 损伤史。 3. 合并严重胫骨平台骨折、股骨远端骨折、膝关节脱位后严重骨性破坏等影响ROI 测量的损伤。 4. 严重膝关节骨关节炎、类风湿关节炎、感染、肿瘤、代谢性骨病或其他明显影响局部骨质/韧带影像学表现的疾病。 5. CT 图像层厚过大、重建质量差、运动伪影明显、金属伪影明显或无法清楚识别 PCL 胫骨止点区域者。 6. MRI 或手术资料不足,无法可靠判定损伤模式者。 7. 研究者认为不适合纳入本研究的其他情况。

Exclusion criteria:

1. Chronic PCL injuries, unknown injury time, or injuries where more than 6 weeks passed before imaging. 2. History of surgery on the same knee or a known previous PCL injury. 3. Combined severe tibial plateau fracture, distal femur fracture, severe bone damage after knee dislocation, or other injuries that affect ROI measurement. 4. Severe knee osteoarthritis, rheumatoid arthritis, infection, tumor, metabolic bone disease, or other conditions that obviously affect local bone/ligament imaging. 5. CT images with too thick slices, poor reconstruction quality, obvious motion artifacts, significant metal artifacts, or inability to clearly identify the PCL tibial attachment area. 6. Insufficient MRI or surgical data, making it impossible to reliably determine the injury pattern. 7. Other situations the researchers believe are not suitable for inclusion in this study.
