What is the test to assess for a meniscus tear?

The Apley’s grind test (Apley Compression test) is used to evaluate individuals for problems of the meniscus in the knee. This test is named after Alan Graham Appley (1914 – 1996), a British orthopedic surgeon, who discovered this assessment technique.

What is a positive meniscus test?

The test is considered positive for a torn meniscus if the examiner appreciates a palpable or auditory click while rotating and extending the knee.

What is a medial McMurray test?

The McMurray test (also known as the McMurray circumduction test) is used to detect internal tears in the knee joint. It is a procedure by which the knee is systemically rotated to identify where tears in the cartilage (called the meniscus) may have occurred or developed.

What is the normal ROM for the knee?

A fully bent knee will max out at about a full range of motion of 135° degrees of flexion. As a general rule, a knee flexion of about 125° will allow you to carry out most normal activities. For daily living, a minimum flexion of around 105°-110° is required.

What does a negative McMurray test mean?

A false positive is when the test is positive suggesting a meniscal tear is present when, in fact, there is no tear. The more specific a test is, the fewer the false negatives. A false negative refers to the patient who has a negative McMurray test as if nothing is wrong when there really is a meniscal tear present.

What is a positive Lachman maneuver?

A positive Lachman test or pivot test is strong evidence of an existing anterior cruciate ligament (ACL) tear, and a negative Lachman test is fairly good evidence against that injury. Although widely used, the anterior drawer is the least helpful maneuver for diagnosing an ACL tear.

How do you self diagnose a torn meniscus?

To test for a lateral meniscus tear (on the outer side of the knee), you’ll be asked to turn your toes inward as far as your knees can rotate. You’ll then squat and slowly stand up. A click or pain can indicate a meniscus tear.
