Knee Orthopaedic Test: McMurrays Test

McMurray's test is a physical examination maneuver used to assess the presence of meniscal tears in the knee joint. Here are the steps to perform the test:

1. Ask the patient to lie down in a supine position with the affected leg straightened.
2. Grasp the patient's heel with one hand and flex the knee to 90 degrees.
3. Place the other hand on the patient's knee with the thumb and index finger positioned on either side of the joint line.
4. Rotate the lower leg externally by placing the foot in an outward direction with your hand while simultaneously applying a valgus (inward) stress to the knee with your other hand.
5. Slowly extend the knee joint while maintaining external rotation and valgus stress on the joint.
6. Listen and feel for a clicking, snapping or popping sensation in the knee joint as it reaches full extension. This may indicate the presence of a meniscal tear.
7. If no clicking, snapping, or popping sensation is felt, repeat steps 2 to 6 with the lower leg internally rotated, while applying varus (outward) stress on the knee joint.
