Abstract

Background: Osteochondritis Dissecans (OCD) is an idiopathic process and can progress from stable to cartilage fragmentation with the formation of loose bodies in the affected joint capsule. Loose bodies in the knee may wear out the articular cartilage, tendons, and ligaments, leading to a series of problems, such as joint locking, bouncing, joint effusion, and meniscus tear; therefore, early recognition and treatment of intraarticular loose bodies are important to achieve favorable long-term outcomes.

Case report: A 49-year-old male presented with a 1-month history of right knee discomfort. The patient underwent a knee MRI scan and was diagnosed with OCD. A short-term MRI follow-up with a thin-layer PDWI sequence without fat suppression detected the cartilage fragments in the knee capsule. Loose body removal, cartilage repair, and microfracture surgery were performed under arthroscopic surgery, and loose bodies of cartilage fragments were removed.

Conclusion: Short-term MRI follow-up and thin-layer PDWI sequence without fat suppression are necessary for detecting cartilage loose bodies.

短期MRI随访及无脂肪抑制的薄层PDWI序列检测软骨松体1例。

背景：夹层性骨软骨炎（OCD）是一种特发性疾病，可以从稳定发展到软骨碎裂，并在受影响的关节囊内形成松散体。膝关节内的松散体可能磨损关节软骨、肌腱和韧带，导致一系列问题，如关节锁定、弹跳、关节积液和半月板撕裂；因此，早期识别和治疗关节内松体对于获得良好的长期预后非常重要。病例报告：一名49岁男性，右膝不适1个月。患者接受了膝盖核磁共振扫描，并被诊断为强迫症。短期MRI随访，无脂肪抑制的薄层PDWI序列检测到膝关节囊中的软骨碎片。在关节镜下进行松体取出、软骨修复、微骨折手术，取出松体软骨碎片。结论：短期MRI随访和无脂肪抑制的薄层PDWI序列是检测软骨松体的必要手段。
