knee joint in dogs

The knee joint joins the thigh with the leg and consists of two articulations: one between the femur and tibia, and one between the femur and patella. It is the largest and most complicated joint in the human body. The knee is a mobile trocho-ginglymus (i.e. a pivotal hinge joint), which permits flexion and extension as well as a slight medial and lateral rotation[WP,unvetted]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the knee joint is

The knee joint joins the thigh with the leg and consists of two articulations: one between the femur and tibia, and one between the femur and patella. It is the largest and most complicated joint in the human body. The knee is a mobile trocho-ginglymus (i.e. a pivotal hinge joint), which permits flexion and extension as well as a slight medial and lateral rotation[WP,unvetted]. The atlas records it as a joint at the organ scale in the dog.

Where the knee joint is

It sits in the hindlimb, within the skeletal system. Only the region is known. The position shown is somewhere plausible inside it and nothing more.

What the knee joint connects to

The atlas records 11 typed relationships for it, across 6 kinds of connection. part of knee and limb.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the knee joint. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as joint of knee and articulatio genus. Searching any of those names reaches this page.
