Yes. Great question, Alan. And look, it starts and ends with our team and our people. We have a resilient, dedicated group at Bioventus. And that goes across our business from our sales team to everyone that supports our sales efforts. That dedication, coupled with our strategy, translates into what you're seeing today. Now to peel that back a little further, if we start with our joint pain treatments, our HA products itself, that is normally a first line of defense. And as we've talked about, as long as patients feel comfortable going to the doctor's office for treatment, we're in good shape with that therapy. We have excellent reimbursement. We're the only company with a single, three and five-injection. We've certainly seen the single injection through the pandemic continue to accelerate in usage. And we think with our DUROLANE product which is the highest molecular weight HA product on the market today, we'll continue to see penetration of market share with that product. The product is that good. And with GELSYN, our three-injection which is still a small, overall relatively small percentage of the three-injection market, we expect to see continued market share gains there as well. When you look at our other products, we are very diversified and broad. We cut across a large swath of orthopedics. We deal with thousands of orthopedic surgeons on a monthly basis. And that really lends that diversity to the balance and the growth that you consistently see from Bioventus. Even with advanced rehabilitation, we have seen terrific things from the Bioness team in that area where their call point is largely post-stroke patients with the gait restoration device I mentioned, the pilot, the L300 Go. And that's been a huge success this year. We continue to see good things from Exogen. And even with the headwinds with bone graft substitutes, we saw 4% growth when large areas of the country where we're highly penetrated curtailed elective procedures. And once again, that goes down -- and bone graft substitutes, to our strategy of being agnostic to spinal hardware, being able to work with every spine surgeon no matter what spinal implant they use and be able to offer a superior product and a very dedicated sales team that sells that product. So at the end of the day, as I started out, it comes down to our people, it comes down to our culture and certainly the ability to execute that type of strategy in a very diversified setting that we have.
