The posteromedial corner seen from a side view,

demonstrating a semimembranosus coming down
0:08
from posterosuperior to anteroinferior.

The main tendon, which is known as the direct arm,
0:16
which is deep, dark on MRI and fan-shaped,
0:20
depicted here as a yellow...
0:23
sorry,
0:23
depicted here as an orange dotted structure,
0:27
may then bifurcate into an anterior arm and the direct
0:31
arm continues on down. The anterior component,
0:34
or tibial arm, is also known as the reflected arm.
0:38
It also goes by the name of pars reflexa.
0:42
So, the direct arm is the arm that you're most likely
0:45
to see. The other arms are more minor.
0:48
Perhaps you may be able to see the distal arm when the
0:51
knee is swollen and inflamed as the expansions may
0:55
separate and you're unlikely to see
0:58
the inferior popliteal arm.
1:00
There's also a capsular arm that
1:01
blends with the capsule,
1:03
but it also blends with the capsular component
1:06
of the POL or Posterior Oblique Ligament.
1:10
So the knee capsule, POL,
1:12
and the capsular reflection of the semimembranosus are one.
1:16
More on the POL in a separate discussion.
