They should have had a re-scan, consulted with the doctors and have a clear course of action by now.
That said, the fact they've been silent tells me there is no surgery planned, it's healing on schedule and they'll continue with conservative treatment. KA won't want to embarrass Jack by coming out and saying... "see I told you so, no surgery, you're healing on schedule... be patient".
If the scan looked bad, then they would've come out and said they're moving forward w/ surgery and give timelines on his recovery... but that hasn't been the case.
