How do you test for knee instability?

Stand and then balance on one foot (the side you want to test). Perform a single-leg squat while trying to keep your body as straight as possible. If you’re able to balance so that you’re knee is straight about your hip for about one-half of the deep knee bend and the return up, then you pass the test on that side.

Doctors at NYU Langone often use ultrasound to diagnose muscle, tendon, and ligament injuries. This is because ultrasound uses high frequency sound waves to produce an often clearer picture of soft tissue, such as muscles and ligaments, compared with X-ray images.

How do you check for knee inflammation?


  1. X-ray. An X-ray can rule out broken or dislocated bones, and determine if you have arthritis.

We’ll evaluate the ligaments on the inside and the outside of the knee. So we’ll basically have the knee, drop it over the side of the table, flex it about 30 to 40 degrees and stress it outside and stress it inside. This tests the medial collateral ligament and the lateral collateral ligament.

What does a positive McMurray’s test mean?

The examiner then rotates the leg internally while extending the knee to 90 degrees of flexion. If a “thud” or “click” is felt along with pain, this constitutes a “positive McMurray test” for a tear in the posterior portion of the lateral meniscus.
