Lelli Test

Description

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
