The therapist compresses on the patella posteriorly onto the femoral condyles and then moderately moves the patella distally.

Pain, crepitus, apprehension
With the client prone, the therapist flexes the clients affected knee, trying to bring the heel to their glutes, while making sure the client’s affected leg doesn’t abduct.
The pelvis on the affected side flexes as you try to get their heel to touch their glute.
