Document Summary

Lecture 20 radiographic anatomy of the knee. Knee: the knee is two shallow sockets (two condyles of the femur articulating with the medial and lateral menisci) but they are highly constrained unlike the shoulder, does(cid:374)(cid:859)t have the (cid:373)ulti-directional requirements of the shoulder. Therefore it is effectively a hinge joint: only flexion and minimal extension (some congenital predispositions for hyperextension) Rings maintain stability and require all layers to maintain structural integrity and strength in movement. Layer 2 = meniscus (deepens the socket like the labrum in the shoulder) X-ray, ct, mri really good, ultrasound and nuclear imaging quite limited. Can see all the surfaces of the bones, use x-rays to see pathological processes i. e. fractures, other more fine fractures (single trauma vs. stress fracture thickening around small fracture, weakest part is at cartilage) Sometimes fractures are very subtle for serious knee damage (segond fracture) because it causes acl or mcl disruption.
