The Quadriceps Active Test is used to assess the integrity of the PCL or posterior cruciate ligament of the knee.
How to Perform Quadriceps Active Test
Position of Patient: The patient is positioned in supine with the hip at 45 degrees and knee at 90 degrees of flexion, similar to the position of the posterior drawer test. The patient’s foot should be flat on the table and stabilized by the examiner’s body.
Performance: The examiner will instruct the patient to activate their quadriceps muscle as if the patient was attempting to kick into knee extension against resistance.
