- Dr. Ebraheim’s educational animated video describes the anatomy of the knee joint.
•Femur
•Tibia
•Fibula
•Patella
•Joint capsule: articular surface of the femur and articular surface of the patella.
•Femoral condyles
•Meniscus
•Anterior cruciate ligament
•Posterior cruciate ligament
•Medial collateral ligament
•Lateral collateral ligament
•Quadriceps muscle attached to the patella
•Patellar tendon
•Hamstrings muscle at the back of the knee
Several bursae are seen around the knees
•Suprapatellar bursa
•Prepatellar bursa
•Infrapatellar bursa
•Pes anserine bursa
These bursae allow the knee cap to slide freely underneath the skin while bending and straightening the knee.
The area of depression located at the back of the knee is called the popliteal fossa.
Posterior view of the knee
Posterior cruciate ligament
Muscles:
•popliteus
•Plantaris
•Soleus
•Biceps femoris
•Semitendinosus
•Semimembranosus
•Gastrocnemius
Popliteal fossa: neurovascular bundle in the fossa
•Popliteal artery and vein
•Tibial nerve
•Common peroneal nerve
Both the tibial and the common peroneal nerves arise from the sciatic nerve. The sciatic nerve travels down the thigh to the area of the popliteal fossa and at this point it divides into the tibial and common peroneal nerves.
The popliteal fossa is a closely packed space. It is bounded by the biceps femoris laterally as well as the semitendinosus and the semimembranosus medially. The lower part of the space is formed by the two head of the gastrocnemius muscle.
On the medial side of the knee, you can find the arrangement of the tendons inserted in the tibia and the medial collateral ligament.
On the medial side of the knee you can see the biceps femoris tendon and the iliotibial band. You can also see the lateral collateral ligament.
The articular cartilage of the knee is different from the meniscus. it is worn out by aging and wear and tear. This condition is called osteoarthritis. The hyaline cartilage becomes roughened and bumpy.
Injuries around the knee
The quadriceps tendon, the patellar tendon and the patella cause active extension of the knee. Any disruption, the patient will be unable to actively extend the knee.
In anterior cruciate ligament injury the tibia moves forward. In a posterior cruciate ligament injury the tibia moves backward.
Rupture of the collateral ligament of the knee, lateral or medial, will cause abnormal side movement of the leg.
Inside the knee between the femur and the tibia you will see the meniscus. healing of meniscal tear is good at the periphery because of good blood supply.

Maashaallah
Liked every vedio of urs
The way of ur explanation with live pictures makes me understand very much faster
Jazakallahhu khair
Since a while I do learning anatomy with educational means like those of Dr Ebraheim. Keep on your excellent educative tutorial and teaching. :) with all my gratitude. Christiane
I love all of your video. But some just only have music. Why don't you put some voice instructions in all videos. Thanks
Excellent video... That voice kept me awake n attentive 😆
Another great teaching video!! Thank you.
Easy to follow video! I understand knee anatomy so much better now :)
Thanks for educating us. Keep it up Sir!!
really easy anatomy of the knee.
THANKS
these videos make studying way easier. staring at the pages of a lab manual only help so much,,,
Simply excellent. Very grateful for clear, concise and well presented video. Thank you for the great channel. 6/8/2018 😊
A Great Video! Thank You Dr. Ebraheim!
thank you
ur all videos are awesome sir
thank you so much for sharing ur deep knowledge with us sir now i can understand knee joint much better and waiting to watch more new videos of urs
CHANGE IS GOOD
that nasal, shrieking, sharp voice would crack glass ... totally destroys the presentation ...Nabil should know better ! !
loooool
LOL.. yes sorry to say but the it ruins the presentation as the voice is so distracting
@Olivia Janz Kordell You’re an idiot.
Great Video! Forgive me for butting in, I would love your thoughts. Have you researched - Dinanlinson Rocky Position Approach (search on google)? It is a great one of a kind guide for learning how to fix chronic knee pain without the headache. Ive heard some extraordinary things about it and my mate at very last got astronomical success with it.
Thank you everyone for the kind words.
Audio sound painful 😖
Great vid Dr!
*LOOK* *!* *WHO'S* *TEACHING* *US* :D :D
Excellent video!
I have a question. Why does the meniscus have a blood supply? Or rather how? Isn't the meniscus made of fibroCARTILAGE and cartilage is avascular. Also, fibrocartilage does not have a perichondrium either. So is this specialised cartilage which HAS its own blood supply? Thanks!
very good video
Brilliant revision - thank you!
good work
So much gain on that voice. Jesus
is arthritis curable? except for surgery is there any thing?
your voice and music was good . why did you change it?
please fix the quality of sound..
Good
Marmara Besyo'dan selamlar.
Painful audio.
the phone was up loud and it scared the shit out if me
Sir use easy word as possible as
j
it is kinda lame structure, overcomplicated and still the range of motion is limited, no real side support, and beacause of its complexity the knee is prone to injury... who did this lame work???
evolution did.
iuno777 if you thought well about it you'll find that it's a very professional work, I'm amazed!!
captive flame agree
+iuno777 ! the mobility and stabiilty(i.e balance and resistance to injuries) are inversely related... ALLAH has specialized our knee joint to left the whole weight of our body and to provide us stability and enough strength to help us in our walking, there is no fault in it...
An architectural masterpiece is what it is, every structure perfectly adapted for seamless movement and balance, all perfectly indicative of a creator all wise and all knowing
Typical loud Dr
THANKS
thank you
THANKS
THANKS
THANKS
Your videos help tremendously sir🌹❤️
