Drawer test
Drawer Test
The Drawer Test (pronunciation: /drɔːr tɛst/) is a clinical examination procedure used by medical professionals to assess the integrity of the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL) in the knee.
Etymology
The term "Drawer Test" is derived from the action of pulling and pushing the knee joint, similar to the action of opening and closing a drawer.
Procedure
The Drawer Test is performed with the patient lying down with their knee bent at a 90-degree angle. The examiner will hold the patient's foot in place with their own body, while their hands are placed around the patient's knee. The examiner will then attempt to pull the tibia forward and push it backward, similar to the motion of opening and closing a drawer.
If the tibia moves forward more than it should (compared to the unaffected knee), it indicates a potential injury to the ACL. If the tibia moves backward more than it should, it indicates a potential injury to the PCL.
