Posterior Drawer Test assesses which ligament?

Explanation:
The test focuses on the posterior cruciate ligament, which normally prevents the tibia from moving backward relative to the femur when the knee is bent. To perform it, the knee is flexed to about 90 degrees and a posterior-directed force is applied to the tibia. In a healthy knee, only a small amount of posterior translation occurs with a firm end feel. If the PCL is torn or lax, the tibia will translate more posteriorly and the end feel may be soft or absent, indicating PCL injury. This contrasts with the anterior drawer test, which screens the ACL by pulling the tibia forward, and with tests for the collateral ligaments (MCL/LCL) that assess side-to-side laxity with valgus or varus stress. PCL injuries can occur from dashboard-type impacts or hyperflexion injuries.
