i have had 2 on my knee.
the first op was unsuccessful although the doc said it all went well.
couldnt stand the pain, and so i visited another doc who operated.
he said the first op was substandard
he told me that he removed alot of floating bone that was missed in the first op and was pain-free within a few days.
and so...get a second opinion from an expert.
this was more than 10 years ago, and the knee is great..pain free and strong.
good luck
