[|Human|] i had knee surgery 5 years ago. and have seen 6 doctors and had 3 different types of surgery to see if any thing would help. nothing. i take norco every 4 to 6 hrs and only have relief for a couple of hours. now i had my other knee done and i have the same problem, even the pain shots do not help
[|AI|]  Hello, I have studied your case. You may need bone scan to see increase uptake near knee implant. This uptake increased due to loosening of implant or infection around implant. This can be differentiated by investigate like CRP, CBC, ESR.PCR culture is very useful if infection is suspected to find culprit organism. PET SCAN will also give more details. If infection is confirmed debridement/ revision operation is required. Hope this answers your query. If you have additional questions or follow-up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care.
