I've had lots of problems with my knees (mainly left) due to dislocating my patella twice and once on the right, after some extensive rehabilitation i am starting to get my confidence back and worked really hard trying to strengthen the muscles arond my knee's, over the past 3 months i have increased the weights ive been lifting and ever since my right patella feels out of line (too high)and even a little twisted!. It hurts going up stairs and down, and ive no idea what to do to bring it back down, i'm only 23 and hate to think what problems i'll have when im older!!
