00:00:03.023 --> 00:00:07.083
The patellar apprehension test evaluates for
pateller subluxation or dislocation.

00:00:07.083 --> 00:00:12.013
With the knee extended, push medially and laterally on the patella in an attempt to

00:00:12.013 --> 00:00:14.209
sublux the patella.

00:00:14.209 --> 00:00:18.109
If it is painful or the patient becomes apprehensive about the movement, it is a

00:00:18.109 --> 99:59:59.999
positive test.
