Q

• The articular surface of the intercondylar notch is (fibrous/hyaline) cartilage. Anteriorly we see it covering most of the anterior region.

That is a (non-weight bearing/ weight bearing) zone of the distal femur that does not make contact with the tibia and is an area where ligaments attach.

60
Q

Anteriorly, the synovial capsule of the knee is pretty close to the fibrous capsule, except it is behind the patella and it runs just (superficial/deep) to the fibrous capsule in the medial side, the lateral side, and even on the posterior side. When you get to the posterior midline it dives deep towards the anterior portion of the knee, comes back around on itself to wrap around the ____ ligaments.

63
Q

A

does not

64
Q

If you tore your ACL, your ligaments have blood vessels, and because it is wrapped so tightly in that synovial layer, if you tear your ACL you are going to tear the (fibrous/synovial) layer of the knee and then blood enters into the capsule. That shows the importance of the cruciates not being intra synovial, but extra synovial.
