This is not medical advice. The content is intended as educational content for health care professionals and students. If you are a patient, seek care of a health care professional. With a torn Anterior cruciate ligament, the tibia will subluxate anteriorly on the femur during extension. During the pivot-shift test, you induce the subluxation and subsequently test for spontaneous reduction indicating a positive test.

It eseay explanation God bless u
I have the app already thanks
Aspiring PT here! Just found your channel, and I'm learning so much already! Thank you for your videos! :)
Awesome Melissa! Glad you found us and we can help you with your learning process! You're welcome - thank you for subscribing!
Excelent video and well explained. Really appreciated it
The illustration at the end really helped me to understand what is happening with the patient! Thank you so much!
You're welcome Wauneta!
Amazing Video. Thank you!
I am your follower from Egypt and I benefit a lot from your videos
+Ebtehal M thanks a lot! Glad we can help!
This is awesome and very helpful. Thanks! Video was very well made. I've subscribed!
+M Bagis thanks a lot
My ACL re-rupture only showed up on pivot shift, lucky the third guy I saw knew how to do the test :)
Very useful, informative video and it was demonstrated very succesful. Thanks. Love from Turkey 🇹🇷
Love back from Amsterdam!
Really appreciate your work👍👍
Thanks for the feedback! And glad we can provide some value!
This video was awesome,, thanks!!!!
Thanks for the compliment and for following us!
thank's, nice work,really beneficial
You welcome!
Hi, beyond 40 degrees, is the Tibial subluxaton reduced by the ITB as the knee is taken into further flexion after the give- way feeling?
My knee specialist did this & detected my torn ACL perfectly
My GP did the Lachsman test & couldn't (so referred me to the specialist)
My GP needs to learn this technique.!
Thanks!
Ur welcome
nice:)
thank you! you saved my grade! This is exactly what my teacher asked me!
+Tak Hang Siu awesome! Glad we could help! Congrats 🎊
thank u💜
Ur welcome!
Wonderful!! You are making difficult things easy to learn. Best of luck n many thanks.
That's our goal - happy we succeeded!;)
good videos thnx
Thanks for the compliment Damith!
Great videos as always from you guys! Quick question on the mechanics. The ACL helps to prevent anterior displacement of the tibia, so I don't understand why the tibia moving posteriorly (reducing or jogging back) during this test indicates an ACL tear. Any clarification would be great. Thanks!
The subluxation occurs in the beginning of the movement and when the ITB tightens the tibia is shifted posteriorly. What they call "jog". That is what I think anyway!
In the beginning there is internal rotation and valgus force given. This (somehow) causes anterior subluxation of tibia, which an intact ACL would have prevented. So basically at the start of the test, we may have subluxated the tibia, but we don't know that yet.
As we keep on flexing the knee, at about 30° the IT band pulls it back to it's original position i.e, reduces it. (It's clear in the anatomical diagram shown in the video) Which means, it was actually subluxated to begin with, which means there's an ACL tear.
You are creative in physical therapy 👍🏻,
I'm waiting for your new videos 😊
+5ial Rasam thanks 🙏🏼 we try to illustrate concepts in a visual way! Thanks for following
We post twice a week
I am now studying to be a physiotherapist, the second year, what do you recommend, what I focus on more .
+5ial Rasam get good at the basics. Understand the key principles of rehab (tissue healing phases, load management, etc)
I don't know the specifics of your curriculum but for example we had a lot of freedom choosing our clinical placements and they were a key point to our development. Choose a direction you like. We love ortho so a big focus was put on that
I understand, thank you very much 🙏🏻
Content cop intro music!! The video is already great :)
+Kieran Thompson haha we realize we have quite some iDubbz fans on our channel :)
Keep up the great work, I'm studying sports science at Loughborough uni and these videos are really helping me!
Glad to hear, we certainly will!
This test is for identify Posterolateral corner injury
I must not have had a complete ruptured maybe grade 3 tear because my knee would give out after a ski accident and a pivot shit test was the only way to confirm not even an mri or Lachmams test would works
Good day. When you say the tibia reduces or jerks backwards does it subsequently sublux anteriorly/forwards? Thanks
The tibia subluxes anteriorly in the beginning phase of the test by the internal rotation and abduction/valgus component in case the ACL (+ possibly the posterolateral corner is torn). Reducing means that the tibia is 'repositioned' so drawn back on the lateral side because of tension in the ITB.
Thank you sir
Where are the links of the other 2 tests for ACL that you've mentioned in this video?
+The Humming Boy are they not added yet?
You can otherwise find them on our channel page or a collection on our website
Where we assemble tests by pathology
i hope you found them on the channel. i have added the endcard annotations now
Thanks for the helping PT Students like me, i just want to ask if you guys are using Orthopedic physical Assessment by: David Magee, because i was using it same time watching you vids and every thin you say is like carbon copy of the book.. thanks :D
+theportsmass Mass that's is the book we used during our bachelor studies and if we can't find a suitable research article. So yes, sometimes we are staying very close to that book although the more we learn the more it becomes obvious that it's definitely not the gold standard.
Great video, can you please repeat the last line:the test can produce a clunk sound and something about walking, sorry I didn't catch the last part. Thankyou
The patient describes the feeling (experience) as the “giving way feeling that they know from walking”
@@Physiotutorsyou mean the sensation just before it gives way (or feels like it's about to give way)
I have had this injury for 20 years now 😳
niceeeeeee
genu recurvatum bilateral
And how to cure that itb
Ur not curing the ITB, for an ACL tear you will need rehabilitation.
Another name for pivot shift test la? M....what sir
Cannot catch
Please try to translate video to arabic
Poor explanation. Just some technical terms thrown in, the typical medical babble you find on any medical page with no expanding on those terms and a once going through the motion. No nuanced approach, no examples of actually how one ruptured looks like or what contribution lateral pressure has. After all it is a LATERAL pivot shift test.
Unfortunately we can't make everyone happy. Not sure what you mean with medical babble and which words you mean in particular? In a video we have limited time to explain medical jargon.
Agree that it would be ideal to have patient's with an actual torn ACL and PLC, but it's next to impossible to have them available for videos.
Lateral pressure / valgus force increases the subluxation of the tibia on the femur.
@Helmaerl Cheny: Do you want them to write your thesis for you, too? By the format of their videos, it is quite clear that their target audience isn't the general population. I would expect the people that end up here to already be familiar with most of the terminology, or at least be willing to look it up. If you were expecting 1-3 minute videos to substitute for sitting down to read whole chapters, I think you're in for quite a disappointment. I mean, don't get me wrong... I too would love to just browse their channel for a few days and VOILÀ! be a physical therapist. But yeah, I think they're actually going for short demonstrations in a condensed format (while still managing to consult several sources and present the best available evidence, might we add), to aid in the visualization of tests and measures.
PS. Not sure how you expect them to present live examples of all pathologies being discussed throughout their channel, but hey... you could always upload a video yourself.
Can NOT Understand your enunciation of The English Language. Your Eastern/North Eastern European Broge, Accent is TOO Rich. In Addition, I find, it is not helpful following your methods without your pointing out Layman's terms, coupled with the medical names, definitions and location... (i.e. LATERAL/Outer, MEDIAL/Inner, Anterior/Front, Pasterior/Back...) Do I want to go to Medical School to learn ALL the Terms you are referring to, No. I'd like a reference to "self-test" my knee pain from CZcams, NOT have to enroll into John Hopkin's University, in order to relate to where and what you are referring to. I will search elsewhere.
