Overview & Considerations
A physical examination shows signs of torn meniscus. This includes various manipulations of the joint.
- Pain on the joint line in the area of the meniscus tear.
- In the McMurray's test, the health care practitioner will have you lie on your back while holding the heel of your injured leg with your leg bent. Pressure is placed on the outside of the knee with the practitioner's other hand, and the leg is straightened with the foot turned in (internally rotated). Pain and/or a click over the middle of the joint indicate a middle (medial) meniscal tear.
- For an Apley's compression test, the health care practitioner will have you lie on your back with your knee bent at a 90 degree angle. The practitioner will grab your foot with both hands and rotate it to the outside (lateral rotation) while a downward force is applied to the foot. The practitioner's knee and thigh may be used to stabilize your thigh. Pain in the middle of the joint may indicate a middle (medial) meniscal tear.
- A ballottement test for synovial effusions (excess joint fluid) is positive in meniscal tears, indicating swelling with fluid around the joint. This test is a physical examination test that allows the practitioner to detect the presence of fluid in a body space.
