Patellar Apprehension Test | Patella Dislocation Assessment

Dislocations of the patella are a fairly common sight in sports and Kai can has experienced it himself during his active soccer career. While these are usually traumatic incidences, genetic predisposition can play a role as well. Factors that may influence the risk of dislocation are among others the sulcus angle and sulcus depth. 

Nunes et al from 2013 conducted a scientific review and meta-analysis on clinical tests for the diagnosis of patellofemoral pain syndrome which included the patellar apprehension test. Upon pooling the positive likelihood ratio for the patella apprehension test is reported at 1.3 and the negative likelihood ratio at 1.0 which is why we attribute a weak clinical value to this test.

To conduct the test, the patient lies supine with the knee flexed to 30°. The quads should be relaxed to allow passive movement of the patella.
With the thumb of both hands, press on the medial side of the patella to exert laterally directed pressure. 

In a positive test, the patient may be surprised by the lateral displacement of the patella and feel uncomfortable or apprehensive as the patella reaches the point of maximal lateral displacement. The patient may even reach for your hands or attempt to straighten the knee to pull the patella back into a relatively normal position.

Another orthopedic test for patellar luxation / patellar instability is the moving patellar apprehension test.

    The Assessment E-Book (Spanish Version) Excelente Libro electrónico, me gusta que esta basado en la evidencia clínica y me apoya mucho para mi practica clínica. Es el mejor libro que he visto de evaluación, y me gusta mucho que esta en constante actualización, estaría bien meter más evaluaciones funcionales, que ya comienzan a subir en los videos con la nueva integrante mujer al equipo. Gracias kai y Andreas.

    The Assessment E-Book I can’t believe this extremely inconvenience interface of this book. I’m used to reading my physio books with kindle, ipad just swiping the page back and forth, but this book , you need to tap the arrow on the left corner of the book to turn the page..even space bar and enter key don’t work to turn the page..it’s feel like read a book in the computer in 1990s..

    The Assessment E-Book A must-have for all physiotherapists, osteopaths and manual therapists. The authors conducted an extensive research on assessment tests in manual therapy. I find it very easy to read. The more I read the more I learn. Thank you!

    The Assessment E-Book Very helpful during my study and making clinical decisions. You have made the test descriptions perfect for every region! Compliments! Loving the extra information (screening/guidelines) that comes with the cervical spine and the lumbar spine. Looking forward to see those as well for the other regions.

    The Assessment E-Book (Spanish Version) Un libro genial!!! Pero le doy 4 estrellas en vez de 5 ya que no me gusta el poder abrirlo solo en dos dispositivos. Tengo 2 ordenadores (uno en el trabajo), un móvil y una tablet, pudiendo abrirlo solo en dos de ellos. Por lo demás, un libro muy recomendable.

    The Assessment E-Book These are probably the best 80€ that I have ever invested in a book. Absolutly greatful for your work. It has been such a great effort, that you have put into this book and together with your videos, it really helped me to pass some exams and to later decide which assessment to use for my patients. I can only recommend this book to every single physiotherapist or physio student!!!
    thumps up, guys

    The Assessment E-Book The best way to spend 80euros. Totally worth it. The amount of work you put behind this must have been absolutely huge. Every physical or physiotherapist should own it.
    Congrats guys you’ve done an incredible job.
    I’ve learnd a lot of new things and my approach to therapy in general have totally changed.
    In one word: amazing. Keep going guys ! Best wishes from france.

    The Assessment E-Book Got me through my assessment exams with a breeze would not have been as easy and enjoyable without the assessment handbook. It provides relevant data, and insights into statistical values and the lay of the land on the research side of things. A great book and a must for any physiotherapist, student, or practitioner...
