DM as a risk factor for quadriceps tendon rupture?

Can anyone explain to me why DM would be a  risk factor for quadriceps tendon rupture. My 19yo daughter, with DM tore this tendon and much of the online information about it lists diabetes as a risk factor. Curious.


Perhaps high glucose damage those tissues like it does the vascular system and other organs. I think the sugar makes tissue brittle.

The endocrine system controls hormones and many other factors - such as elecrolytes.  Your muscles and other cells need proper nutrition and metabolism and DM impacts your bodys ability to keep everything balanced.
