Godfrey's Test is used to assess injury to which ligament?

Explanation:
Godfrey's test looks at posterior stability of the knee, specifically crowding in the back when the knee is bent. When you perform it, the patient lies on their back with hips flexed and knees bent about 90 degrees. If one tibia sags backward compared with the other, giving the tibial tubercle a posterior drop, that’s a positive posterior sag sign. This happens because the posterior cruciate ligament (PCL) normally resists backward movement of the tibia relative to the femur. If the PCL is injured, gravity can pull the tibia into a more posterior position when the knee is flexed, so the tibial plateau appears to drop back. That makes Godfrey's test most indicative of a PCL injury. Other ligaments aren’t the focus here: injuries to the ACL are better detected with anterior-based tests (like the anterior drawer or Lachman), and MCL/LCL injuries are assessed with varus/valgus stress tests. Godfrey's test is specifically about posterior tibial displacement, which points to the PCL.
