Execution
- 1Position the patient supine with the knee supported.
- 2Control the foot and proximal tibia while placing the knee into the described rotatory-stress position.
- 3Apply valgus stress and tibial rotation to bias the anterolateral structures.
- 4Move the knee through flexion and extension while watching for a shift.
- 5Record the presence of subluxation, reduction, apprehension, or side-to-side difference.
Positive outcome
A rotatory shift, giving way, clunk, or apprehension is positive for ACL-related rotatory instability. The test is not interpreted as isolated ACL laxity unless supported by straight anterior tests. Side-to-side comparison is important.

CommentDejour-type rotatory tests are part of the broader pivot-shift family. I kept the entry conservative because modern high-quality diagnostic data are usually reported for pivot shift rather than this named variation. Use it as a rotatory instability adjunct, not as a primary ACL test.
