What is Attenuated patella alta and explain in detail?
Attenuated patella alta is an extremely rare condition affecting mobility and leg strength.   It is characterized by an unusually small knee cap (patella) that develops out of and above the joint.  Typically, as the knee cap sits in the joint, it is stimulated to growth by abrasion from the opposing bones.  When not situated properly in the joint, the knee cap does not experience such stimulation and remains small and undeveloped. Note that the cartilage under and around the kneecap is eight times smoother than ice, so "abrasion" may not be the best term.A similar condition, patella alta, can occur as the result of a sports injury, though the large majority of the time it is a congenital/developmental condition that is unrelated to trauma
