VIDEO 1: Tibial thrust test

The tibia, in the cranial cruciate ligament-deficient stifle, will subluxate cranially relative to a motionless femur. This results in passive cranial motion of the index finger overlying the tibial tuberosity as seen in this video. A positive result is recognized as an increase in the distance between index finger and thumb as the proximal tibia moves cranially with respect to the distal femur.

VIDEO 2: Cranial drawer test

The tibia, in the cranial cruciate ligament-deficient stifle, can be displaced cranially relative to the stable femur as seen in this video.
