Internal rotation of the leg during McMurray's test is indicative of which condition?

The maneuver tests for meniscal tears by stressing the menisci with tibial rotation during knee extension. Turning the tibia inward (internal rotation) places stress on the lateral meniscus; a positive sign—such as a painful click or catching—suggests a tear in the lateral meniscus. The medial meniscus is stressed with external rotation, not internal rotation. MCL sprains are assessed with valgus stress tests, and gluteus medius trigger points aren’t diagnosed with this knee maneuver. So internal rotation pointing to a lateral meniscal tear fits best.
