I dislocated my kneecap in karate class while doing a roundhouse kick to the punching bag.Luckily my dad knew 1st aid and popped it back in.It swolled up slightly and i couldn't fully extend my leg without feeling a "tired feeling in my leg".Now a week has gone by and I can stand up on my own without any help but I have a heavy limp when i walk on it so now I use crutches.I have it wrapped in a brace too and I notice keeping it elevated helps alot too.Im going to try and see a doc if it dosen't improve by next week and get it x-ray'd.Anyone here ever dislocate their knee and how long did it heal?any tips?
