All right, feel free to come to the microphones for any additional questions. I'll start. What's the ceiling of function that you'll allow for your patients after this, Dr. Kosters? If they wanted to return to run or competitive sport, that would be okay? Yeah, that would be okay. They can do immediate full weight bearing and sometimes this is also a point for them. For example, if you have somebody who runs his own business, he can't do a partial weight bearing for eight weeks or something. And sometimes this is a point for them to go for the metal implant. And corresponding tibial sided wear, is that something you've seen or you avoid it by recessing that a little bit below the surface? Yeah, you can avoid it in my opinion. But again, the alignment is crucial in this thing and the meniscus. If you have a varus more than three degrees, I would recommend to correct the alignment like you do in biological repair. Dr. Gertz, I know where your allegiance are. Why? Thank you. Dr. Kosters, thank you. Question, what's your turnaround time to get this implant? We saw some significant disease progression on that MRI to the arthroscopy and going from a fairly small lesion to something bigger. What happens when you get into the case that now your lesion is bigger than the implant that you have? And do you have any concern with that implant being countersunk? We saw that that lesion was articulating against the posterior horn of the medial meniscus. Is that going to put that at risk in your mind? If the lesion is bigger than the implant, you shouldn't go for it. I think if it's in the posterior or medial or posterolateral part of the implant, maybe you can do it. But if it's in the full weight-bearing area, you shouldn't go for it. And the meniscus was, if you have a concomitant meniscus root here, or what do you mean? No, I mean, you said that the implant slightly countersunk against the cartilage on the MRI that we saw that was sitting right up on the meniscus. Do you have any concern that this is going to? No. Okay. Thank you. Thanks. In the interest of time, why don't we go ahead and pull up the voting while we give Mike a little love. Mike, talk me through your rehabilitation. Are you falling prey to any of these expedited rehabilitation protocols for return to high impact sport for these osteochondrographs? I think there's a difference between OC-Graft and Macy. Obviously, Macy has to take and has to develop. Osteochondral allograft, that's fresh viable cartilage. That's a piece of bone and cartilage that's viable with viable chondrocytes. So I do rehab them pretty expeditiously. I mean, I usually have the partial weight bearing right away, full weight bearing just after a few weeks, and return to sport usually between four to six months. I have seen people have returned to sport even prior to that. And biologic adjunct on the backside? Excuse me? Biologic, PRP, bone and marrow aspirate? Yeah. I mean, I soak it in PRP, but there's new things out that you've got these sort of like carbon dioxide systems where you could sort of clear out the marrow elements as opposed to using pulse lavage, which I do think there's a role for that as well. I don't know if you've used it. You can really see the trabeculae of the bone, and you can soak it in there. But I don't know if we've got great data to support it. I mean, there's been some papers pro and con using BMAC or PRP. I don't think that we've achieved consensus on that by any means. All right. Well, I think the comeback is about to start, but we'll go ahead and call it here. It's rigged. It's rigged. This one's rigged. This one is rigged. David, they rigged it again. All right. Thanks, everybody, for engaging session. Thanks, Dr. Marks.
