Blood type O at increased risk
Came across this today
https://pubmed.ncbi.nlm.nih.gov/11086753/
60% of patients with an Achilles tendon rupture belonged to blood group O, compared with 51% of the population as a whole.
28% of the Achilles tendon rupture patients belonged to blood group A, whereas 35% of the general population were members of this group
Small study so take with a grain of salt.
I'm O
