MR and CT arthrography of the knee

Area of Science:

• Radiology
• Orthopedic Imaging

Background:

• Magnetic Resonance (MR) and Computed Tomography (CT) arthrography are valuable tools for knee joint evaluation.
• Established indications include postoperative assessment, chondral lesions, and intra-articular bodies.

Purpose of the Study:

• To review established and potential indications for MR and CT knee arthrography.
• To compare these modalities with conventional imaging.

Main Methods:

• Review of established clinical indications for MR and CT knee arthrography.
• Discussion of techniques, normal variants, and common pathologies.
• Examination of emerging indications like ACL injury and autologous chondrocyte implants.

Main Results:

• MR arthrography is indicated for postoperative meniscus, chondral lesions, and intra-articular bodies.
• CT arthrography is crucial for internal derangements when MRI is contraindicated.
• The review covers established pathologies and potential new applications.

Conclusions:

• MR and CT arthrography offer distinct advantages for specific knee conditions.
• These imaging techniques are essential for comprehensive knee assessment and diagnosis.
