@kathleen1314 wow. You are incredibly literate on this process and I value that. Sadly we all paid a price for the areas of medical literacy we possess.
Orthovisc is the brand I was given. I have had no reactions to it but I recently had my q8w infusion of immunosuppressant so I’m not sure my body could muster an inflammatory response :).

My brother also recommended a brace to help preserve what I can of knee architecture since i’d like to think about an October surgery timeline.

Instinctively - since i have no actual knowledge - I am babying the knee today and shaking it around so i don’t pinch anything or step off with something not quite aligned. Other than that i am watching and learning what not do :)! I can have another cortisone injection between now and surgery if needed. But the surgeon tells me he would hope i don't need it.

Thanks for your reply!
