Which statement best describes the posterior drawer test final position and result description?

• A. The knee is extended and tibia translated anteriorly; positive with increased anterior translation.
• B. The tibia is translated laterally with knee flexed; positive with lateral gapping.
• C. The knee is flexed about 90 degrees and the tibia is translated posteriorly; positive with lack of end-feel or excessive posterior translation.
• D. The test uses varus stress to assess LCL.

Answer: (C)

The key idea is that the posterior drawer test checks the posterior cruciate ligament (PCL) by pushing the tibia backward when the knee is bent. In the normal knee, the tibia doesn’t move much and there’s a definite end-feel. When the knee is flexed to about 90 degrees and the tibia translates posteriorly with an absent or soft end-feel, that signals PCL laxity or tearing. This contrasts with other tests: anterior translation at 0–30 degrees tests the ACL, while lateral translation with varus stress tests the LCL. So the described final position—knee flexed about 90 degrees with posterior tibial translation—and a positive finding of lack of end-feel or excessive posterior movement correctly identify the posterior drawer result.
