Is Lachman or anterior drawer more sensitive?
Lachman’s test is more sensitive than is the anterior drawer sign. One reason may be that it is difficult for the patient to contract his hamstrings and thus prevent forward sliding of the tibia when the knee is in only 20 degrees – 30 degrees of flexion.
What is anterior drawer of the knee?
The anterior drawer test is a physical examination doctors use to test the stability of the knee’s anterior cruciate ligament (ACL). Doctors may use this test, along with images and other exams, to determine if a person has injured their ACL and recommend treatment options.
What does a positive anterior drawer test demonstrate with an injured knee?
Anterior translation of the tibia associated with a soft or a mushy end-feel indicates a positive test. More than about 2mm of anterior translation compared to the uninvolved knee suggests a torn ACL (“soft end-feel”), as does 10mm of total anterior translation.
What does a positive drawer test mean?
If the tibia pulls forward or backward more than normal, the test is considered positive. Excessive displacement of the tibia anteriorly suggests that the anterior cruciate ligament is injured, whereas excessive posterior displacement of the tibia may indicate injury of the posterior cruciate ligament.
How reliable is the anterior drawer test?
Results of the anterior drawer test were positive in 79.6% of the patients, in 98.6% patients having the Lachman test, and in 89.8% of patients having the pivot shift test.
What is anterior drawer test for ankle?

What does a positive anterior drawer test demonstrated in a patient who has an injured knee?
What does a positive ankle anterior drawer test indicate?
In a positive ankle drawer-sign finding, there is a difference in movement in a relaxed patient between the injured side and the uninjured side, with the injured side having more movement than the uninjured one. Sometimes, a dimple appears over the area of the ATFL on anterior translation.
How to test for an anterior drawer sign?
Testing involves having the patient flex the knee at a right angle while the lower leg is grasped just below the knee and moved first toward, then away from the examiner. The test result is positive for the knee injury if the head of the tibia can be moved more than a half inch from the joint. See also anterior drawer sign or test.
What does the cranial drawer sign stand for?
anterior (cranial) drawer sign. cranial, nonrotary movement of the proximal tibia in relation to the distal femur. Normally restricted by the cranial (anterior) cruciate ligament and used as a diagnostic test for rupture of that structure.
