I had an arthroscopy done and they didnt find anything? i have had knee pain for over 4years?? ? - knee pain after arthroscopy

I always had a bad knee, he had an MRI and showed nothing, so I learned arthroscopic surgery. When I woke up, said everything he did was to the knee was clean, I was half awake and could'nt ask him at that time. not that all right? But I still have pain? its worse when I swim and are always ways, if I start? I am very confused! Can anyone help?
