The human body's connective tissues help minimize direct stress on the hinge joint bones, until injury, aging or disease compromise the connective tissue.
Well there you have it, free internut medical advice is worth every penny.
I will make sure that I correct the obviously deluded medical professionals who worked hard to guide me in restoring the strength and range of motion of my left ankle. (The ankle is not a single joint.)
Just stand with your feet at 90 degrees to each other. So “unnatural” that it is comfortable.
SMH.
p.s. Sit in a chair. Cross your legs so that one knee is on top of the other, one foot on the floor. Write the alphabet with your top ankle. (Real PT exercize.) If you can only write the letter I, listen to the free internut advice.
