With Picmonic, facts become pictures. We've taken what the science shows - image mnemonics work - but we've boosted the effectiveness by building and associating memorable characters, interesting audio stories, and built-in quizzing.
DOWNLOAD PDFThe patient will be lying prone with the testing knee flexed to 90 degrees. The clinician will stabilize the patientâs femur to the table, passively distract the tibia from the knee joint, and slowly rotate the tibia internally and externally. If this rotation and distraction is more painful or demonstrates increased rotation, the injury is most likely ligamentous. The clinician will then apply a compressive force to the knee and, again, slowly rotate the tibia internally and externally. If this rotation and compression is more painful or shows decreased rotation relative to the normal side, the deficit is most likely due to a meniscus injury.
The patient will be lying supine, and the clinician will hold the patientâs heel of the testing foot with their hand and then passively flexes the knee. The knee is then passively allowed to extend; it should be able to fully extend, or âbounce home,â with a sharp end feel. A positive test for a torn meniscus is indicated if full extension of the knee is incomplete or has a rubbery end feel.
The patient will be lying supine with the testing knee in maximal flexion. The clinician will passively internally rotate and extend the knee to test the lateral meniscus. The clinician will passively externally rotate and extend the knee to test the medial meniscus. A positive indication is the reproduction of a âclickâ and pain in the knee joint.
The patient will be standing on one leg (uninvolved leg first) with approximately 5 degrees of knee flexion while the clinician provides their hands to assist with balance. The patient will rotate the femur on the tibia laterally and medially three times. This will be repeated with 20 degrees of flexion. A positive test is indicated if the patient experiences medial or lateral joint pain/discomfort or a sense of locking/catching in the knee.
