Any Suggestion For Having Bone On Bone Showing Several Hot Spots Mean?

I had a nuclear bone scan on my knees. The left knee which I had a TKR on 10 years ago showed nothing. The right knee which I am told is bone on bone and needs a replacement showed several hot spots. Does this mean I have an infection and if so, would it be in the tissue, the bone, or possibly both? Thank you, BH

Hi, I have read the details posted by you.
Hot spots on nuclear scan show that your bone turnover is high in the bones concerned. Infection is diagnosed by other means. A higher activity is seen in any condition like Osteoarthrosis, Fractures ,etc. It is better to discuss the report with your doctor, who on seeing the clinical condition will be able to interpret better.
