Thank you, David. Good morning. Maybe quickly here, 20 seconds big picture, and then I'll talk about the U.S. So, big picture. It was a good quarter. We here at Zimmer Biomet deliver 5.6% ex-FX. As I noted in my prepared remarks, this is the 10th quarter in a row growing mid-single digit or above. And we're pleased with the double-digit growth in adjusted EPS. S.E.T. performed above expectations, third quarter mid-single digit or above. I'm pleased to report that for the first time in a while, every single business within S.E.T. -- and there are six of them, actually grew, which is something we didn't see before. Enabling technologies, which is robotics primarily, grew double digit in Q2. It grew double digit in Q1. The U.S. grew -- robotics grew 16% in the quarter, so strong in that regard. And as we announced this morning, we did close the gaps in hips that we had, which frankly is one of the reasons why we lost market share. Just throwing the summary to highlight the fact that unlike five years ago, we're not just a U.S. knee-centric type of company. That said, relative to knees and the U.S. performance, look, David, not pleased with the quarter. It was softer than expected. And what I will tell you is that there are three main reasons why we did not do better in the U.S., and these are solvable reasons. The first one is, we had a large amount of high volume surgeons -- Zimmer Biomet high volume surgeons that were out of the territory for a variety of reasons. We hosted large medical education events and we did have a large group of surgeons that were not performing surgeries in the quarter. The second piece is that we had some challenges from a supply standpoint when it came to one of our knee platforms, what we call limb salvage, which is part of knee revision cases. These are high ASP cases. And candidly, this didn't help the quarter. And then the third reason on why knees in the U.S. was softer than expected is comps. We delivered knee growth of 10% -- almost 10%, 9.8% to be exact in Q2 of 2023, which was close to mid-single digit, and the U.S. grew 5%. So, comps didn't help. So, in the background of those surgeons being out, supply constraints, the comps didn't help out. What I will tell you is that these three elements have gotten resolved as we move out of the quarter and sitting here, July behind us, the U.S. Recon performance is very strong. On the second part of your question, David, cementless continues to track very nicely. Candidly, I hope we can get more sets out. The adoption rate is very high. We are converting accounts and we hope to have cementless not just in the U.S., but outside of the U.S. very soon. So that's the summary of what's happening here in the U.S.
