it is more common for it to dislocate more often

Question 21

torn ligament without joint dislocation are considered

minor disrepair

sprains

twist

snaps

Answer 21

sprains

Question 22

ligaments have very good vascularization so they are easy to heal after injury, this is why sprained ankles heal quickly
