Показать описание
The Patella apprehension test is used to diagnose patellar instability, most commonly lateral patellar instability.

How to Perform Patellar Apprehension Test
Position of Patient: The patient should be in supine with the leg flexed to 30 degrees.

Performance: The examiner instructs the patient to relax and places both thumbs along the medial aspect of the patella. In this position, apply pressure against the medial side of the patella. This movement directs the patella laterally and may cause apprehension.

How to Interpret Patellar Apprehension Test
Positive Finding: A positive test occurs if the patient demonstrates apprehension or attempts to move the leg or knee to prevent lateral patellar dislocation.

Hey Tim🌸
Indeed a sweet and short explanation!
How do we know that this test comes positive? I mean what should be the criteria? Does the patient resists this manoeuvre or what?
