Osteochondral injuries require early recognition to prevent arthritis. Advanced imaging, particularly MRI, is crucial for diagnosing and staging these injuries, differentiating between surgical and non-surgical lesions.

Area of Science:

Orthopedics and Sports Medicine
Radiology
Musculoskeletal Imaging

Background:

Osteochondral injuries are a significant cause of musculoskeletal trauma.
Untreated injuries can lead to debilitating arthritis.
Joint anatomy and biomechanics influence injury patterns and imaging findings.

Purpose of the Study:

To review the imaging of osteochondral fractures and osteochondrosis dissecans (OCD).
To highlight the differentiation of surgical versus non-surgical lesions using advanced imaging.
To emphasize the role of modern imaging modalities in diagnosing and staging these injuries.

Main Methods:

Review of imaging techniques for osteochondral injuries.
Focus on Computed Tomography (CT) and Magnetic Resonance Imaging (MRI).

Discussion of newer strategies like MR arthrography and contrast-enhanced MRI.

Main Results:

Advanced imaging, especially MRI, enhances detection and characterization of osteochondral injuries.
MRI is the preferred modality for diagnosis and staging due to its sensitivity.
MRI effectively depicts marrow edema, fracture clefts, and articular cartilage morphology.

Conclusions:

Accurate imaging is vital for appropriate management of osteochondral injuries.
MRI provides superior sensitivity for detecting and staging osteochondral lesions.
Advanced MRI techniques aid in distinguishing stable from unstable osteochondral fragments.
