The Clarke's sign or Patellar Grind Test has long been used in the assessment of patellofemoral pain or chondormalacia patellae but it appears that the test has a low clinical value and should no longer be used in practice.

Thank you! Was really helpful for my orthopedic exam!
physio-cheerios lol. you guys are the best, I can always rely on your videos when studying.
Thanks a lot for all the videos, they make me easier to prepare for the license exam.
That's the goal - you're welcome!
I have an orthopedic examination and your videos really helped guys.. thanks a lot👍🏻🎉
follower from Egypt 😊😊
Thanks, that's our goal! Good luck with your studies Salma!
I have had an MRI to confirm grade 4 CMP on the left and grade 2 CMP on the right. Never had this test performed throughout the diagnosis process but as a physio student I thought I'd give it a try. It was very painful on the right, then extremely painful on the left. Wasn't expecting the pain to be so intense
How are you now
Thanks for sharing videos on special tests
Ur welcome Arti! Thanks for following us!
Thank youuu!
Thanks!
Wow! Never knew this existed. Thank you again :)
So amazing
Super vid
May it‘s important to mention that the downward pressure on the Patella should not be that high.. otherwise the test is always positive..
You want to fixate the base of the patella. What do you suggest to do differently?
The literature suggests otherwise, namely that the test rather has a bad sensitivity (lot of false negatives compared to relatively low true positives)
Physiotutors I meant to say that if you put too much pressure on anybody’s patella, they will always have pain when activating the quad. Otherwise everybody in my PT class would have Chondromalazia patellae :D
Great
Thx
great work guys, keep it up, the videos really really helped me for my musculoskeletal exam preparation and also for performance , can't Thankyou enough 👍👍💯💯💯...us(physio) students really need guys like you to make these videos 👍👍, just keep it us and thankyou!!
Thanks for the compliment Maggie this is why we have started the channel a couple of years ago! Thx for following!
Physiotutors welcome 😊 keep it up and wish you all the best!
I just did this test in myself and it hurts a lot. I haven’t been able to play soccer for 2 months. I can’t run, squatting hurts, and I’m just depressed right now.
Exactly how I feel man. It sucks.
Nah thats lig tear
How are you afyer 9 months?
Bro??
Go see an orthopaedic
شكرااااااا
While doing the Clark's test, what does grating unaccompanied by pain sifnify
Do you have any videos on radial nerve testing in the forearm?
Check out the ULTT3 for the radial nerve: czcams.com/video/rir6x6Iiqc4/video.html
Physiotutors thank you
Kunt u mij alstublieft helpen ik ben bijna 16 en heb al ongeveer een half jaar dit in het begin viel het best mee hoeveel pijn ik had maar de laatste tijd heb ik echt het gevoel dat ik dood ga echt serieus ik krijg meestal s’avonds heel veel pijn dat ik bijna niet kan opstaan en zitten soms huil ik heel de nacht door en slaap ik terwijl ik huil ik was naar de huisarts geweest hij zegt het gaat over of je moet sporten maar sporten doet nog meer pijn en de pijn ligt in / random mijn knie schijf en als ik daar zoveel pijn heb gaat het zelfs verder naar onder mijn voeten daar heb ik dan ook veel mijn alsof iemands e bijt en ook heel raar s’avonds krijg ik ook heel veel pijn aan mijn vingers (knokkels/duim) en heupen en rug sorry voor mijn lange verhaal maar ik heb echt hulp nodig ik ben echt bang en ik ga volgende week weer een afspraak maken want door die vorige heb ik nu nog veel meer pijn! 🥺😭😭😭🙏
Do you know the Rabot sign? I can't find a lot of information about that. it's is possible that is has an other name I do not know...Thanks a lot
wo liegt der Unterschied zum Zohlen-Zeichen?
Hello bro I hear sound from knee when i sit or rise ....plz tell me whats problem?
Hey Bilal, i understand that noisy knees can cause you to be worried. However usually knee cracking is nothing to be concerned about and actually pretty normal.
We have made a video about it that you can find by searching for „Physiotutors why knees crack“. this video should answer all your questions. If you are still unsure we advise you to book a personal consultation with our partner at yourphysio.online
what if i have a grinding sensation with very little pain
Jeeeezzz he's hooot
Stolen from the European "Zohlen Test" Sign is very obvious. Still its a good learning video
Not familiar with the Zohlen Test
Thanks for the comment
IS pfps detected in MRI?
My MRI report: Normal knee joint
But it is painfull !!
💯🎯👏🏼👏🏼👏🏼
✨
My patella makes alot of noises when i do this, no pain tho.
What if there is a little grind but no pain?
its also because of hip and upper leg wrong alignment
That was the underlying theory but the correlation between alignment and complaints is not there

What is the solution weightlifters? I went through over a month of physio for PFPS and the pain returns as I resume training, my physio referred me to an ortho because he thinks it's chondromalacia. Still not lifting the weights I could before the injury, I am hoping it does not require surgery!
A month is NO time at all to work on PFPS. Rather give it 3-6 month, especially considering that you want to lift heavy weights again. One of the most crucial points is to adapt your load and to very slowly build up the intensity and volume of your training.
Keep working on your hip and quadriceps and increase volume during weightlifting as tolerated without pain.
"Chondromalacia and malalignment are findings that almost always do not need to be "corrected" to relieve pain." (Post et al. 2017)
Thank you! I should have clarified. My injury happened in late March and I went to PT for one month, but continued to do the corrective stretches (improving femoral IR) for another month with very conservative loads. I can lift lighter weights without pain, but just a minor tickling sensation across the patellar sometimes. I am increasing the loads and volume again slowly after 2 complete weeks off.
You're welcome. PFPS is not an injury, it's a symptom complex and often caused by a sudden increase in load on the PF joint. Think we discussed earlier that improving internal rotation does not make much sense to us as only very little internal rotation is necessary for the squat.
With PFPS, you should focus on the hip abductors and external rotators, as well as the quadriceps.
For the rest, keep increasing your load gradually and give your body (and cartilage) time to adapt.
Thanks again. It was a sudden buckling of the knee under a heavy but not max squat after multiple sets (160kg). At the eccentric portion above parallel I felt a sudden rubbing movement. I could train the next day fine but after enough volume my knee would be so bad I couldn't train at all after 15 minutes (could not air-squat without pain). After that, I had all the usual PFPS markers: theater signs, increased crepitus, pain going up/downstairs etc. but they are gone now and only come back for a few hours after light training.
My PT told me he thought the asymmetry in IR in my left leg (less than 10 deg on the left) was responsible for a compensation pattern that maybe hurt the underlying cartilage, by excessively pushing out the knees. I turn out negative on this patellar grind test but he still thinks I should see an ortho if it does not improve. I will follow your advice and continue a gradual increase in loading and strengthening hip rotators! McConnell taping helps a little bit. Should I place a priority on front squats to emphasize the VMO? I thought the strength-asymmetry between lateral/medial heads theory was now discredited.
No worries. It's hard to give good advice without seeing you in person. We'd suggest to even lower the weight until you don't have pain after training at all anymore and slowly increase from there. Your cartilage needs time to recover.
