McMurray's test
Last reviewed 01/2018
This is a rotation test for demonstrating a torn meniscus. The tear may cause a pedunculated tag of meniscus which may become jammed between the joint surfaces.
Held by one hand which is placed along the joint line, the knee is flexed to 90ø while the foot is held by the sole with the other hand. The ankle is internally rotated and the knee extended. The manoeuvre is repeated with external rotation of the ankle and at varying degrees of knee flexion.
A tag, caused by a tear will cause a palpable or even audible click on extension of the knee.
The 'normal' leg must be checked for completeness: clicks can arise from normal tendon movement.
