Which of the following clues in Diane's exam or history would alert the clinician to the need for obtaining radiographs?

Question 2
The clinician suspects that a client has patellar instability. In order to test for this, the client is seated with the quadriceps relaxed, and the knee is placed in extension.
Next the patella is displaced laterally and the knee flexed to 30. If instability is present, this maneuver displaces the patella to an abnormal position on the lateral femoral condyle, and the client will perceive pain. Testing for patellar instability in this way is known as:
a. Apprehension sign.
b. Bulge sign.
c. Thumb sign.
d. None of the above
