Yes. And I assume you're referring to 1Q '24, 1Q '23, but. Yes, yes. So I think -- so as we talked about earlier, obviously, a great first quarter from a kind of P&L perspective across the board, margin expansion, the pull-through is very high, et cetera. I do think on the gross margin side, sort of our expectation for quite a while, our kind of, call it, midterm expectation was to get to that 70% plus on a gross margin level. And obviously, our guidance this year is at 70%. And I would say, certainly, as I talked about earlier, it could ebb and flow kind of within a year when you look at margins or pull through, but on a full year basis, that is kind of tracking in a very good place to kind of get to those targets.
And I would say from a gross margin perspective as well, I mean there's definitely a lot of efforts right now kind of thinking about in the right way, where can we find efficiencies within our processes, across our spend, vendors, et cetera. And that's going to be pretty important as we move into a new facility in the next couple of years as well. So I think a lot of work on the gross margin side and sort of a lot of focus to kind of make sure we're driving kind of the right savings there. On the kind of operating expense side, as part of your question, I mean, there are some investments that we will need to make. I mean, we referenced arthro MACI, there's some development costs there, but obviously, that's an important initiative.
Similarly on ankle over the next few years that will kind of make its way in the P&L. But that doesn't change from a bottom line perspective, our expectation to be trending toward that 30% adjusted EBITDA target that we've talked about for quite a while as well.
So I think it really starts with the top line growth, but a lot of focus on kind of making sure kind of managing the rest of the P&L, but it also just shows just the operating leverage kind of within the business, particularly as we start to scale. So I think Q1, obviously, was a great quarter, but I think a good starts the year, but as we think over '24 and '25 and beyond, I mean, that's going to remain a focus, and we think we'll continue to see that leverage across the P&L.
