oral corticosteroids (such as Prednisone) will always raise blood sugar and length of time this happens depends greatly on the dosage and how long it's taken.

intra-articular injections of corticosteroids (such as Cortisone) is likely to raise blood sugar (there is some debate on the subject, but it's widely accepted to be true) but it really shouldn't last more than 5 days or so.

I'm curious why you got the injection if you are T2 and already a candidate for surgery - I would question your surgeon about this, seems a little irresponsible to me, but I'm not a Dr.

The scare with higher BGs and surgery comes mostly from the increased risk of infection (and slower healing)... are they telling you that you're no longer a candidate because your BGs are so high? I don't think I understood you there.

Also, consider the effect of stress on your BGs - not sure if this knee injury is something that has gotten worse over time, or was the result of an acute injury, but the stress surrounding being injured, having to get surgery, etc. could definitely make your BGs higher.

Lastly, Metformin will take a while to work - I would ask your Dr about supplementing with insulin short term, or another faster acting option if surgery is your priority right now. Another thing you can do is good ol' diet (low fat/low carb for now) and exercise to reduce your BGs - it really does work. Swimming is a great low impact option.
