Anterior Drawer TestAnterior Drawer Test is a specified version of the general Drawer Test both of which are determining tests in the derivation of medical or surgical conclusions about crucial ligaments in a person’s knee. Anterior drawer test is the specific test for assessing the condition of the Anterior Cruciate Ligament of a person’s knee.

Anterior cruciate ligament of the knee is one of the most important components of the knee. The most important function of the anterior cruciate ligament is to ensure that the knee is not overextended. Hence it is often referred to as one of the organs that aid or contribute to stability of a person’s knee. Sometimes they are also called stabilizers.

Procedure and technique of the Anterior Drawer Test are not at all that complicated. The person on whom the test is about to be done is asked to lay down with his face facing the ceiling with a straight body and torso. After this, the patient is asked to flex his hips to about 45 degrees.

This can be done by perpendicular bending of both the knees of the patient with the sole of both the feet touching the platform on which the patient is lying down. When this is done the doctor or his assistant sits on the same platform in front of the toes of the patient. Although many physicians and surgeons perform this test by seating themselves on the toes of the person whose anterior drawer test is being conducted. Conducting the test by sitting on the toes is considered to be the most appropriate method generally.

It is also said to give more defining results. The doctor or his assistant thereafter holds the leg of the patient below the tibia. After this is done the doctor or his assistant try to create a movement of the leg in an anterior manner.

The various intricate movements and positioning of the leg must be done with efficiency as per the exact method of the anterior drawer test for the correct conclusions to be drawn. If the flexing of the hips is not done to the required 45 degrees or the bending of the knee is not done perpendicular to the platform the results may be misleading.

The results of the anterior drawer test are considered positive if the extent of movement is excessive or more than normally expected. This is so because there are clear proofs of the anterior cruciate ligament being stretched more than usual and hence abnormal extension of the anterior cruciate ligament is confirmed. The extent of damage or level of integrity remaining in the anterior cruciate ligament is also among the significant conclusions that may be drawn from this test.

Drawer test is a little more varied in performance than the anterior drawer test. Injuries or hyperextension of the posterior cruciate ligament is detected, confirmed and tested by the posterior drawer test. The posterior drawer test and the anterior drawer tests are both very similar to the drawer test and are variations or modifications of the drawer test.
