Hi Pedro, unfortunately I don't have any way at the moment of translating them to Spanish, but would be interesting in looking into this more if there is sufficient interest.
Thanks for this tutorial!!🤍 I want to mention here one clinical correlation,as the medial meniscus is attached to the medial ”Tibial” collateral ligament it’s immobile and this makes it more susceptible for injury.Whereas, the lateral meniscus is separated from the lateral ”Fibular” collateral ligament by the popliteus muscle and faraway from the capsule of the knee joint and this makes it freely mobile and less liable for injury.
What you have shown is purely osteology, I would request you to add some muscles, ligaments, and also some movements, to add a little more colour, and make it genuinely more interesting
+AnatomyZone interesting points ,if anyone else trying to find out anatomy and physiology courses try Letza Simple Anatomy Lessons (just google it ) ? Ive heard some super things about it and my cousin got great results with it.
@KrzysztofPro This technically isn't a hinge joint because it is biaxial. It is actually a condyloid or modified ball and socket joint because you get flexion and extension along the transverse axis, but as you go into extension the knee medially rotates to 'lock' the knee in place, and inversely you get lateral rotation as you take the knee into flexion. This occurs on the longitudinal axis. That is what he was explaining.
gerrpk A modified hinge joint is just another name for a condyloid joint. In walking you also get some ab and adduction, so there are some argument that this is multi axial joint.
Nope still thinks its modified hinge joint due to having main uni- axial (flexion/extension) movements with limited rotation/sideways movements. (Clinically Insignificant) A condyloid joint is bi-axial. (e.g. the knuckles) with flx/ext ab/ad & circm. When moving it would abduct and adduct in limited amounts due to driving external forces, a chain reaction from ground ankle to knee (valgus). which ain't a proper knee movement. Also ligaments prevent this motion happening too much as it is a weight bearing joint and needed for stability.
Not quite.... The knee is classified as a bi-axial joint - condyloid. The rotation is not a a result of external forces. It plays an very important role in what is called the 'knee locking mechanism' which is incredibly important for the stability of the knee. The medial surfaces of the knee are larger than the lateral surfaces, so when moving into extension the lateral side of the joint completes its motion earlier than the medial side of the knee. Accessory roll and glides continue in the medial compartment of the knee, this results in rotation at the knee joint, if the tibia is fixed then the femur rotates medially. To move from this position into flexion the knee must rotate laterally which requires muscle action (popliteus). This means that in full extension the knee is locked and requires no muscular activity to maintain full extension. In this position there is maximum contact between the joint surfaces making this the most stable position the knee joint can be in. Its called a close packed position. That is why it is bi-axial. I can tell you that as a physiotherapist both functionally and anatomically the knee has to be at least biaxial for even the most basic movements to occur.
I already understand the whole mechanism you just said and is exactly the limited rotation in the knee I was talking about before. Lets go thorough it again.. it permits flexion and extension as well as a slight internal and external rotation (what you just explained) technically making it's a pivotal-hinge joint (i.e modified hinge joint). It's primary movement is flexion and extension and counting the rotational "locking mechanism" is limited and minimal as happens only under a fixed position. (It doesn't rotate like other rotating joints (radioulna jt) but only during flex/ext. and why would need to rotate your knee?

I would say just write down everything you need to know, and look at the model at the start of the video or just look up an unlabeled one on google and just see what you remember.
You have no idea how much you have helped me through the years with these videos. Thank you so much!!
Too reallll
The most helpful anatomy videos on the internet
Great video. I've spent ages trying to determine the difference between the intercondylar fossa and groove.

Do one correction...its condylar type of synovial joint not hinge type
Thanks for this tutorial!!🤍

its a condylar synovial joint
Actually it's condylar joint but as regards to the range of movements allowed in by this joint it may be classified as a modified hinge joint.
Hi, in full extension the tibia is medially rotated and when the knee joint starts to flex the tibia is rotated laterally?
@KrzysztofPro This technically isn't a hinge joint because it is biaxial. It is actually a condyloid or modified ball and socket joint because you get flexion and extension along the transverse axis, but as you go into extension the knee medially rotates to 'lock' the knee in place, and inversely you get lateral rotation as you take the knee into flexion.

It's a modified hinge joint. As it's main action is Flexion & Extension and limited degree of rotation and side movements.

Good Teacher 😌
Hey, nice tutorial! Just wondering, what font are you using for the text in your videos?
Thanks
Knee jt. is a hinge joint (a type of a synovial jt.)...infact most complex synovial jt. in our body
If you think about it, the Femur is quite similar to the Humerus, with the Humerus having a medial epicondyle and a lateral epycondyle...
what would be a better joint for the knee to prevent an acl tear
both. It is a synovial joint and a hinge joint.
Modified synovial hinge joint
Its a condyloid joint
Thank you sooooo much! always so great
How ca I download this program I am a medical student and I really need to learn anatomy in a easy way
Try visible body app
Thank you so much. This helped a lot :)
Very helpful video. Tq
Fantastic tutorial. Where are you from? You don't have the usual American accent :)
I am confused. it says the joint is the largest SYNOVIAL joint. but then later says its a HINGE joint. which joint is it?
Maryam Almustapha hinge joint is a subtype of synovial joint
@@usmanzahid1729 it's right bro
Awesome video
so helpful i learn with not just. anatoy i learn english

thank you so mutch
Very helpful
Thank you
Hey everyone what is the joint between femur and patella ?
Esto sería también de mucho interes para los hispanoparlantes , es decir me encantaría que estos vídeos fueran también en castellano
gracias
Not hinge , its condylar synovial joint.
very good. ...
Awesome!
any one can say where i can test my knoweldege about anatomy
I would say just write down everything you need to know, and look at the model at the start of the video or just look up an unlabeled one on google and just see what you remember.

Good
My knee joint fix it
excuse me what you have shown in time 0.45 sec is not tibia and is fibula
