posterior drawer test
Clinical examination maneuver to assess posterior cruciate ligament integrity by applying posterior force to the proximal tibia.
Full Definition
The posterior drawer test is a fundamental clinical examination technique used to evaluate the integrity of the posterior cruciate ligament (PCL). The test involves positioning the patient supine with the knee flexed at 90 degrees and applying posterior force to the proximal tibia while stabilizing the foot. Excessive posterior translation compared to the contralateral side indicates PCL injury. This test is routinely documented in orthopedic examinations and is considered a primary diagnostic maneuver for PCL pathology.
Usage
Usage note: Always specify 'posterior' to distinguish from the anterior drawer test; results are typically graded I-III.
