Which test is used to assess PCL injury according to the material?

• A. Godfrey's Test
• B. Posterior Drawer Test
• C. Lachman's Test
• D. Anterior Drawer Test

Answer: (A)

PCL injuries are best detected by a sign that shows the tibia sagging backward when the knee is flexed, revealing posterior instability. Godfrey's test does exactly that: with the patient lying on their back and both knees bent to about 90 degrees, gravity pulls the tibia posteriorly. If one tibia sags relative to the other, that posterior sag sign indicates PCL insufficiency. This gravity-assisted, labeling-free observation makes it a straightforward and reliable bedside indicator of a PCL tear, which is why it’s identified as the test for assessing PCL injury in the material. The other tests either assess different ligaments (for example, Lachman and Anterior Drawer focus on ACL) or examine posterior laxity in a different way (posterior drawer), but the visual posterior sag at 90 degrees flexion is the classic sign specific to PCL injury here.
