KNEE BIOMECHANICS | KNEE JOINT MOTIONS # JOINT KINEMATICS

Detailed biomechanical analysis and discussion on Knee joint motions. The possible motions of knee joint that is tibiofemoral joint are- KNEE FLEXION, KNEE EXTENSION, LATERAL & MEDIAL ROTATION,ABDUCTION AND ADDUCTION. This kinematic movement occurs around an instantaneous axis of knee joint.
This video focus on mechanics of knee flexion and extension and in particular axis of motion, the roll and glide occurring along with motions. Knee flexion can occur either as movement of femur on fixed tibia or tibia on fixed femur. The arthokinematics and osteokinematics movement associated with both this movements is entirely different are discussed in detail.
The ACL AND PCL do have a significant role in knee flexion and extension; along with cruciate ligaments the knee menisci also have a significant contribution to knee joint motions.
Further discussion also focus on KNEE RANGE OF MOTION OF FLEXION AND EXTENSION as well as role of muscles in limiting Range of motion

Sir u teach so well...plz make the tutorial of biomechanics for every joint...please... It's a humble request

[@TonysTutorial]

Sure, thats my plan, after knee we will have videos on ankle and shoulder

[@TonysTutorial]

Thank you

[@surabhipandey3879]

Hello sir.. U reallyy teach sooo welll.. Really loving ur lecs.. But sir can u plz do a video on illioibial band n Bursa too. Please sir.. Kind request🙏🙏

[@TonysTutorial]

Very glad to hear...thank you...IT BAND and Bursae is not a very important topic for biomechanics, thats why skiped it..if u can get bck to me thriugh my social media, i think i can get you the video that i send to my students not in youtube but through other platforms

[@manishamasand4716]

Good evening sir Amazing session thankyou sooo much, There is one doubt What about the role of menisci during open chain movement? As the gliding and rotation of the tibia is in the same direction, with flexion the menisci will be deformed posteriorly and with extension anterior?

[@TonysTutorial]

Wow thts amazing question....one of best...yes u r right deformation takes place as u mentioned but to less extent as in nonweight bearing or open chain there less compessive forces acting on the mensici..hence extent of deformation would be less. But there will be deformation same as u mentioned in flexion posteriorlt and in extension anteriorly

[@manishamasand4716]

Good afternoon sir.. Sir i have a question .. As knee joint is a hinge joint so acc. To it , it has only one degree of freedom ....but in books like pamela & cynthia, i studied it has 3 degree of freedom and you also said here this... So it is confusing me... Sir can you make me understand it in a easy way.. Will be so thankful to you

[@TonysTutorial]

Hai rana , good to hear from you...hinge joint has one degree of freedom you are right...good wrk...but knee joint is not a pure hinge joint...its a modified hinge joint and hence it can have more degress of freedom ..modified hinge joints can have more than one degree of motion...

[@saurabhrana356]

Thank you sir🙏🙏🙏 Can i ask one more question?

[@TonysTutorial]

Defintly u can ask any number of questions! Most hppy to hlp

[@saurabhrana356]

Thanks sir... Sir in cynhia i read thar tibiofemoral joint is a double condyloid joint... So sir can you make me understand about this line... As knee is a hinge joint... So it still confusing me... Are hinge joint and double condylood joint same? Or what?

[@saurabhrana356]

Its double condyloid*
