Is the patella a short bone?
Short bones are shaped roughly as a cube and contain mostly spongy bone. The outside surface is comprised of a thin layer of compact bone. Short bones are located in the hands and feet. The patella (kneecap) is also
considered a short bone

What is Type 3 patella?
MRI study shows features of Wiberg type 3 or c of the patella in the term of:
markedly smaller size of the medial facet
.
more vertical orientation of the medial facet
.
What is Wiberg type 2 patella?
Type II: the
medial facet is smaller than the lateral facet and flat or only slightly convex
. The lateral facet is concave. Type III: the convex medial facet is markedly smaller than the concave lateral facet, and the angle between the medial and lateral facets is nearly 90°.
Is patella a ratio?
IS ratio is measured with the knee flexed 30 degrees, to provide the right tension on the patellar tendon for right measurement. It is commonly measured by knee X-ray, Lateral view or MRI, sagittal plane. The
normal range is between 0.8 and 1.2
, with patella baja <0.8 and patella alta >1.2.
Can you walk without patella?
Though
the kneecap is not needed for walking
or bending your leg, it makes your muscles more efficient and absorbs much of the stress between the upper and lower portions of the leg.

- Irregular bone – has a shape that does not conform to the above three types.
What are the 2 types of bone tissue?
