These tests include the pivot-shift test, anterior drawer test, and Lachman test. The pivot-shift test involves flexing the knee while holding onto the ankle and slightly rotating the tibia inwards. [28] In the anterior drawer test, the examiner flexes the knees to 90 degrees, sits on the person's feet, and gently pulls the tibia towards ...
The anterior drawer and Lachman tests can be used to access the integrity of the anterior cruciate ligament. In the anterior drawer test, the person being examined should lie down on their back (supine position) with the knee in 90 degrees flexion. The foot is secured on the bed with the examiner sitting on the foot.
Lachman test The Lachman test is a clinical test used to diagnose injury of the anterior cruciate ligament (ACL). It is recognized as reliable, sensitive, and usually superior to the anterior drawer test .
Increased posterior translation on the posterior drawer test indicates a combined posterior cruciate ligament tear with the PCL injury. Figure 4 Test - The patient lies supine and flexes their affected knee to approximately 90° then crosses it over the normal side with the foot across the knee and the hip externally rotated.

The key in diagnosing a rupture of the cruciate ligament is the demonstration of an abnormal gait in the dog. Abnormal knee motion is typically observed and diagnosis of a rupture can be made by performing the drawer sign test. [7] [9]
