== Technique<br>  ==


The patient is supine and the knee to be tested is flexed to approximately 90 degrees. The examiner then sits on the toes of the tested extremity to help stabilize it. The examiner grasps the proximal lower leg, approximately at the tibial plateau or joint line, and attempts to translate the lower leg posteriorly. The test is considered positive if there is a lack of end feel or excessive posterior translation <ref>Flynn TW, Cleland JA, Whitman JM.  Users' guide to the musculoskeletal examination: fundamentals for the evidence-based clinician.  United States; Evidence in motion: 2008.</ref>
