@Going4fun, It turns out there is a way through the HSS patient portal to direct questions to your surgeon via email. I have sent these two questions in through that method. They commit to respond within 3 business days. It's about time the medical community embraced electronic communications. Otherwise, you're stuck playing telephone tag or scheduling another expensive and inconvenient appointment for even a relatively simple question. I'll post here again when I hear back. In the meantime, I am trying to be kind to my poor THR leg. Looking forward to Jan. 3 (I think).
