Abbreviations
- Osteochondral fracture (OCF), osteochondritis dissecans (OCD), osteochondral lesion
Synonyms
- Osteochondritis dissecans, osteochondral defect
Definitions
- Injury resulting in fracture line extending through articular cartilage and some portion of underlying bone
- May or may not result in displaced fragment
- OCD
- Term historically used to describe OCF of knee in adolescents
- Some believe this is also due to a component of osteonecrosis
- Medial femoral condyle in 85%
- Lateral weight-bearing aspect in 70% of these
