You prolly dont give a shit but if you're stoned like me during the covid times you can stream pretty much all the latest movies on InstaFlixxer. I've been streaming with my girlfriend lately =)

[@daytonwilder7645]

@Skyler Kohen Yup, I have been using InstaFlixxer for since november myself :D

Aiswarya Pp thank you

[@revathir.s8304]

Nice class sir👌🤗🤗.... you made this portion very simple.... i fully agree with you..., that you tell to study this portion compare with ACL(your previous class about ACL is very helpfull to this compare study 👌👌👌)...because i felt it is soo easy to catch this portion.... so am sure it is a easy way to study this topic for everyone.... thank u sir.. thank u sooo much for this type of easy way and good classes 🤗🤗

[@TonysTutorial]

It's my pleasure...........and i m very happy to hear this,......will come up with more easy ways

[@josnamoljohnson1969]

When pcl have more stress and we tend to strengthen the hamstring it more harm to pcl and result in pcl injury same as acl

[@nidhihuria285]

Sir I always watch ur each and every video. Bt plZ teach pathobiomechanics of joint also.. and amuputation also.. I will really obliged

[@TonysTutorial]

Sure, we are coming into pathomechsnics of knee joint sooner....thnk you

[@TonysTutorial]

Its a very glad thing to hear....i guess in three or four days we will reach into knee pathomechanics... and will definlty look into ur requests..

[@nehagiri6885]

Sir ur saying in PCL postero lateral band gives stability during extension nd in neutral position but In pcl postero medial band is there as u say before i can't stand that????

[@DhwaniMehta-ft7tk]

Sir the video is quite helpful 👍can you please upload a video on questions that can be asked in University exam from knee biomechanics & how to answer particular theoretical que in exam please ??? It would help a lot sir....

Heyy can you just say from which sources you are getting this data like from which author book as if ask we can say that from this book!! So please can you tell!!

[@TonysTutorial]

Cynthia c norkin ( joint structure and function), Carol o otis ( Mechanics and Pathomechanics of human joints) Hope that make sense Regards

[@Sambadhe]

Sir, I am diagnosed with grade 1 acl laxity.. My knee movement is not smooth, my knee buckle and pops when flexion at last 10 degree.. Please tell me what to do. Because it hurts and developed grade 1 chondromalecia patella

[@waseemsherief3409]

Since your ACL is lax, you could work on your hamstring and strengthen the hamstrings, which cld help in easing the knee flx aswell. Not a professional (YET), just a thought after studying this topic.

[@saurabhrana356]

Hello sir... Sir it is written in cynthia that quadriceps muscle reduces the strain on PCL at knee flexion angles between 20 to 60 degrees... So what about the other angles before 20 and after 60 degrees... It sounds like gastrocnemius to me as it also initiates with decreasing the strain but later it increases... So in case of quads, is there any chance of increment of strain on pcl if its flexion go beyond 60 degree ? Sir please make me clear about this..

[@saurabhrana356]

Sir🥺🥺🥺🥺🥺🥺🥺????

[@TonysTutorial]

Gastroneumius increases the strain only after 40degree because primarily gastroneumius is pushing tibia forward at intial degrees of knee motion, when it pushes forward it induces anterior translation which increases strain on ACL, therefore at intial degrees it strain ACL. Whereas aftr 40 degree when tibia considerably moves posteriorly because of increasing flexion angle it starts to push tiba posterior and thus will strain PCL as Pcl role is prevent posterior translation.

[@TonysTutorial]

To understand mechanism of quads check out, Durselen L( the influence of muscle forces and external loads on cruciate ligament injuries) its beyond scope of explaining here. Still if u dont get , answers get bck to me , we will figure out...all the best

[@saurabhrana356]

Okk sir i will definitely check durselen L But sir my only ques. Is Beyond 60 degrees of flexion... Will the quads increase strain on PCL or not?

[@TonysTutorial]

I guess u mentioned me you are a 2 nd BPT Student, i would like to get u that the book Cynthia.c norkin is not a book for 2 nd yr undergraduate.It itself is a book for Research followed by Postgraudates and Researches, so most of things like u pointed out are beyond scope of your undrstnding. I m very hppy to see ur curiosity to learn keep it like that and nurture it and now build a base of which u can learn more. I cant just answer an Yes or No because there are studies contradicting, some even contradicts the role of quads in 20-40 degree, some studies say it can decrease and a few say it might increase. So theres no definte answer to it and u can undrstand it when u build some more basics in biomechanics. As from my viewpoint the role of quads in Acl and Pcl is highly complicated we cannot predict it can increase or decrease or dont effect the Pcl beyond 20-40 degree, but we can finalize it can reduce strain between 20-40( that too some contradicts). Great work ...the more u think the less u find answered questions thats learning. And if its for exam point of view you dont have to stdy this as its beyond ur syllabi scope.

[@ninoiii6982]

You make it so easily thx 🤍✨

[@TonysTutorial]

thank u

[@rajendranathimoolam3740]

Sir what u have written in board ALB, PMB, what u r telling is different please correct

[@JamilAkhtar-tg4fi]

Sir ,in the book the bundle of pcl is written as AMB and PLB but we have learnt pcl bundle as ALB and PMB .can you please clear my confusion?

[@mansikhandhar7663]

Jamil, AMB and PLB anterior cruciate ligament he Posterior cruciate ligament me nahi

[@marwaa113]

great

[@leenapatil6594]

If we focus only on quadricep strengthening instead of hamstring it ll more trouble ACL.. n if we focus more on hamstring strengthening instead of quadriceps it ll increase flexion also and trouble PCL also coz PCL gets tight in flexion..

[@TonysTutorial]

ya very true...glad that u got it
