Lelli Test

Lelli test : Clinical test for the diagnosis of Anterior cruciate ligament (ACL) rupture

Lelli test is carried out with patient in supine position, knee in full extension and heel touching the bed.
A clenched fist is placed beneath the proximal calf just distal to tibial tuberosity.
Gentle downwards pressure is applied over quadriceps tendon and the examiner looks to see if the heel ‘lifts off’ the bed.
The test is positive if there is no heel lift-off and indicates likely ACL disruption

Developed in 2005 to better assess the functional aspects of ACL disruption
