During which test can pain on internal rotation indicate a lateral meniscus injury?

The McMurray test is used to assess for tears of the meniscus in the knee, particularly the lateral meniscus. During this test, the patient's knee is flexed, and the examiner manipulates the knee joint while applying rotational forces. Pain during internal rotation of the knee can indicate a problem with the lateral meniscus, especially if a click or pop is also felt during the maneuver.

In contrast, the Thessaly test also evaluates meniscal integrity but involves weight-bearing and tibial rotation in a standing position at various angles of knee flexion. The Apley test combines compression and distraction while the patient lies prone, and it can indicate meniscal tears but does so less specifically. Ober's test primarily assesses for iliotibial band tightness rather than meniscus injuries. Therefore, in the context of assessing the lateral meniscus specifically, the McMurray test is distinctly associated with internal rotation pain indicating an injury.
