Execution
- 1Position the patient supine and controls both lower limbs.
- 2Cross the involved limb over the opposite leg as described for the test.
- 3Apply the required rotatory and valgus stress through the tibia.
- 4Move the knee through the provocative arc.
- 5Observe for a shift, clunk, apprehension, or reproduction of giving way.
Positive outcome
A rotatory shift, clunk, or giving-way response is positive. The finding is interpreted as anterolateral rotatory instability. The test should not replace Lachman and standard pivot shift testing.

CommentThe Cross Over test is an older named rotatory instability maneuver. Exact procedural variants differ across sources, so the file uses a conservative Magee-style rotatory instability framing. Evidence quality is low compared with contemporary ACL tests.
