Posterior Drawer Test (Knee)

Two common tests for posterior cruciate ligament (PCL) injuries are the posterior drawer test and the posterior sag sign. Both tests help assess the stability of the posterior cruciate ligament.

The posterior drawer test evaluates the integrity of the posterior cruciate ligament by assessing for excessive posterior movement of the tibia, indicating a potential tear or injury.

A positive posterior drawer test suggests a potential tear or injury to the posterior cruciate ligament, which could lead to knee instability and functional issues.
