Knee anatomy.

Posterior medial corner on MRI, lateral view.

Let's look at some of the
0:06
minor arms of the semimembranosus expansion.
0:10
You've already heard about the major arm,
0:13
which I'm making a little bit brighter.
0:16
You saw it as a dotted orange structure.
0:19
It is the direct arm,
0:21
or deep head or deep expansion of the semimembranosus.
0:25
Now, I'm going to take it away because it has sent off another
0:29
bifurcation anteriorly, known as the anterior arm.
0:33
The anterior arm goes underneath the POL and it'll
0:37
insert somewhere around this location.
0:41
Now, we've also got higher up,
0:43
already reflected off before you get to the joint line,
0:47
the capsular arm, and it makes a little arc.
0:50
It merges with the joint capsule and it also merges
0:53
with fibers of the posterior oblique ligament.
0:57
In fact, it merges with a capsular or
1:00
superior arm of the posterior oblique ligament.
1:04
The inferior or popliteal arm passes beneath the POL.
1:10
So it's underneath this green structure. Here's the inferior
1:14
or popliteal arm right there, underneath the POL.
1:18
And it attaches to the tibia just above the insertion
1:23
of the deep portion of the superficial MCL,
1:26
which many of you know as the tibial collateral ligament.
1:29
So the insertion of the tibial collateral ligament lies
1:32
in very close proximity to this structure right here,
1:37
which is the inferior or popliteal arm
1:40
of the semimembranosus expansion.
