Execution
- 1Position the patient supine with the knee flexed.
- 2Palpate the posterior joint line or suspected posterior meniscal area.
- 3Move the knee while maintaining posterior joint line contact.
- 4Apply localized pressure to reproduce symptoms.
- 5Observe for a sudden withdrawal or jump response.
Positive outcome
A sudden jump response or sharp posterior joint line pain is positive. The test is intended to suggest posterior meniscus pathology. Local tenderness without mechanical features is less specific.

CommentFinochietto's jump sign is an older meniscus sign with limited modern validation. I kept the procedure conservative because detailed standardized descriptions vary. It should be interpreted only as an adjunct to better-studied meniscus tests.
