What is it?
A tear in joint fibrocartilage may follow injury or degeneration; an MRI finding alone does not establish the source of pain.
Symptoms and important signs
Joint-line or deep joint pain, catching and sometimes locking.
How is it assessed?
History and examination; selected MRI or other imaging.
Care and treatment options
Activity modification and rehabilitation; repair or other surgery in selected tears.
When to seek help
A truly locked joint or inability to bear weight needs early assessment.
