McMurray test

From WikiMD's WELLNESSPEDIA

McMurray test is a clinical examination procedure used in the diagnosis of meniscal tears in the knee joint. It was named after the British orthopedic surgeon, Thomas Porter McMurray.

Procedure[edit]

The patient is asked to lie down with the knee bent. The examiner holds the knee and the foot, providing a valgus (outward) stress at the knee while the foot is externally rotated. The knee is then extended. If a "click" is felt, the test is considered positive.

Interpretation[edit]

A positive McMurray test indicates a possible tear in the meniscus of the knee. However, it is not definitive proof and further medical imaging such as MRI may be required for confirmation.

Limitations[edit]

The McMurray test has been found to have a sensitivity of around 52% and a specificity of around 97%. This means that while a positive test is a strong indicator of a meniscal tear, a negative test does not definitively rule out a tear.
