i first disclocated my kneecap when i was 10. i went to hospital and they put my leg in plaster followed by physio. The physio told me they shouldnt have put it in plaster as its best to keep it moving. The next time it happened it went back in by itself, didnt go to hosp and i just kept it moving and put some ice on and luckily it didnt swell and was normal the next day. Its since happened several times. It happened on monday night, i luckily managed to get it to go back in by relaxing my muscles but its getting on my nerves now. I was just wondering if anyone knew anything about the operation you can have done? i vaguely remember the hosp staff saying something about having hooks put in????
