Execution
- 1Position the patient supine.
- 2Cup the heel and passively flexes the patient's knee fully.
- 3Allow the knee to passively extend while supporting the heel.
- 4Observe whether the knee reaches full extension smoothly.
- 5Note end-range pain, rubbery block, or springy resistance.
Positive outcome
A rubbery block, rebound, or inability to reach full passive extension is positive. The sign suggests intra-articular pathology such as meniscal tear, loose body, or effusion-related block. It does not identify the exact structure.

CommentBounce home is a mechanical-block screen, not a meniscus-specific test. It is clinically useful when true extension block is reported. It should be interpreted with effusion, locking history, and other intra-articular findings.
Low Clinical Value
