Septic arthritis

I got a streroid shot in my knee and soon after I was diagnosed with septic arthritis. How long must I wait for a knee replacement? I have been infusing Vancomycin and Rocephin through a picc line for the past 8 weeks. My last blood lab showed infection at 9. I began at 86. I'm almost infection free I have not been able to walk for 3 months and its not improving at all. My Dr told me I could not get a prosthetic knee for one year at least. I need to find out why and if there is any other options for me. I'm in pain and need help. Please give me some advice. Anything will help at this point. Thank you for your time.

I am really sorry about the outcome following the steroid injection.

I think it is probably the CRP which has dropped and that is a good sign.
I agree that a prosthetic joint at this stage would not be advisable and you should wait a minimum of 6 months after being infection-free. This can only be assessed with certainty by joint aspiration and culture of the synovial fluid.
You need to be under the care of an orthopaedic surgeon.
