1) This is meniscus. They come in a pair for each of your knee and acts as a rubbery bumper in between the joint and absorbs shock of all of your activites.
2) there are several ways the meniscus can be torn because of various kinds of trauma
3) A horizontal flap tear looks like this in real. This photo was taken from the knee of a 30 year old woman with 1 year old neglected acl tear and meniscus injury. With today’s advancement of technology we can rationally repair a lot of these injuries, but such repair becomes infeasible if there is a long period of delay and neglect.
This awareness should be present in all the young people who likes to stay active and retain the function of their knee “bumpers”
