Final answer:
McMurray's Sign is a physical examination test that evaluates for meniscal tears in the knee by bending, extending, and rotating the patient's knee to elicit pain or a clicking sound.
Step-by-step explanation:
McMurray's Sign is a clinical test used to evaluate individuals for tears in the meniscus of the knee. The test is performed by a healthcare provider who will bend the knee, then straighten and rotate it to see if there's a clicking sound or pain, which might indicate a meniscal tear. It's an important diagnostic tool in sports medicine and orthopedics.
Detecting McMurray's Sign involves a physical examination where a patient lies on their back, and the examiner holds the heel and flexes the knee. While the knee is flexed, the examiner rotates the lower leg and tibia first externally (laterally) and then internally (medially) while extending the knee. A positive McMurray's test may suggest a tear in the lateral or medial meniscus respectively, prompting further investigation through imaging or referring for specialist opinion.
