[MR imaging of the knee]

Area of Science:

• Orthopedics
• Radiology
• Sports Medicine

Background:

• Magnetic resonance imaging (MRI) is a cornerstone in diagnosing knee joint injuries.
• It has largely superseded diagnostic arthroscopy for evaluating traumatic knee lesions.
• MRI offers high confidence in detecting injuries to ligaments, menisci, and articular surfaces.

Purpose of the Study:

• To review the fundamental principles of knee MRI examination techniques.
• To describe the normal MRI anatomy of internal knee joint structures.
• To outline typical MRI findings for various knee injuries, including ligament and meniscal tears, patellar dislocation, and osteochondral lesions.

Main Methods:

• Review of established MRI protocols for knee imaging.
• Analysis of anatomical variations and common pathologies visualized on MRI.
• Correlation of MRI findings with known injury patterns.

Main Results:

• Detailed description of MRI techniques for optimal knee visualization.
• Comprehensive overview of normal internal knee anatomy on MRI.
• Illustrative examples of MRI findings in acute traumatic knee injuries.

Conclusions:

• MRI is a reliable and primary diagnostic tool for knee joint injuries.
• Understanding MRI anatomy and pathology is crucial for accurate diagnosis.
• This review provides a guide for interpreting MRI in the context of knee trauma.
