My left knee has been having some problems and i dont know if it is serious or not. on the inside of my left knee next to my knee cap when i bend and straighten it you feel a strange movement like something sliding back and fourth. sometimes this causes me pain and i also think that soemtimes my knee gives out. i have fallen quite a few times recently. about 4 years ago i had a fall which was quite hard and landed on that knee and evey since around that time my knee has been acting up. when i bend and straighten it yo also hear a weird grinding noise and i can feel the movement all the way around the knee to the back and sometimes when i bend and straighten it i get a weird uncomfortable feeling all the way to my foot. it is not always painful so im not sure if i should be concerned
Hello, Cannot say in your particular case, but generally, it is the function that is the indicator of how serious the knee problem is.  So, difficulty in straightening out, fluid distending it, it's moving in the wrong direction are some of the indications that something is broken.  The instability can predispose to even more damage because the knee moves in an uncontrolled way. Small problems still might be fixable with surgery like a loose tendon or a chip falling off of cartilage. Hope I have answered your query. Let me know if I can assist you further.
