Osteochondral Lesion: AI-Powered MRI Assessment
Upload your ankle MRI for AI detection and staging of osteochondral lesions of the talus. Comprehensive cartilage and bone assessment.
Overview
Osteochondral lesions of the talus (OLT) involve damage to both the articular cartilage and underlying subchondral bone of the talar dome. They commonly result from ankle sprains or repetitive trauma and can cause chronic ankle pain and mechanical symptoms. MRI is the gold standard for evaluating OLT size, stability, and associated bone marrow changes. Our AI consortium stages lesions according to established classification systems and maps the precise location on the talar dome.
Common Symptoms
- Deep ankle pain that worsens with activity
- Ankle swelling, often intermittent
- Catching or locking sensation in the ankle
- Pain with weight-bearing activities
- Stiffness after periods of rest
- Persistent pain despite treatment of ankle sprain
Key Imaging Findings
- Focal cartilage defect on the talar dome surface
- Subchondral bone marrow edema beneath the lesion
- Detached or partially detached osteochondral fragment
- Subchondral cyst formation indicating chronicity
- High T2 signal fluid undercutting the fragment suggesting instability
- Medial or lateral talar dome location mapping
Frequently Asked Questions
What is the difference between a stable and unstable osteochondral lesion?
A stable lesion has intact overlying cartilage and no fluid undercutting the fragment on MRI. An unstable lesion shows fluid signal between the fragment and parent bone, cartilage disruption, or fragment displacement. Our AI evaluates these stability criteria to help stage the lesion.
