Chapters Transcript Video LEGION™ CONCELOC™ Cadaveric Surgical Technique This video demonstrates the technique used with the LEGION™ CONCELOC™. Yes. OK. Right. So here's our resection, here's the surface, right? So then we we'll use the single line one first. Yes, the real thing. OK? You can see the fit so you can walk it pretty good, right? So this was pretty decent bone and with the single line reimer, I think you can see since this is oversized, you can see it's all the way down. Can you see that? That's the poorest coating is against the bone there. So that's pretty good, right? I like that. And it's not coming off. OK. So we previously had prepared these femurs and tibias. OK. So we take this, determine your rotation. I do it both by the an atomic nature of the implant and also by eyeballing the tibial tubercle, we're gonna pin this down. OK? So now it's pinned down. So the first thing we're going to do is we're going to show you both ways we're going to do the kind of the reaming thing and then we're also going to do just the punch. So, yeah, ream just like that. Got it down. Yes, this is the one we're gonna punch. So you could also use this thing, if you don't want to ream you could just punch or if you're a surgeon room just punch. We have this tower, it uses the same handle that you can see that we just took off. So let's, yeah, flips on like that. So punch, I got the hammer here, I got it. And here's the tibial prep. All right. Yeah, it's down good. Oh, yeah, I see that. That's pretty cool. All right. We need the Reamer, the drill on reverse. You wanna take the trial out now? Yep. So now it's ready for the implant. Ok. So here's the tual preparation, right? You see that? And, yep, let me move this for you. So this to be, yes. Tibias first. Then femur get it set. So what I like to do is get it set with, with this and then use the free hand Impactor. So then this, you don't, won't have any bias, like by switching your hand or whatever it kind of just will go down. It's a great feel. Right. A little bit up in the backs to this argument. Nice. I'm pretty sure every one of your surgeons will be happy with that fit. Let's see if this will even go on there. I can't even get this knife under there there. I can. All right. Let's see. Can you look like the knife in there? And I can't even get the knife a little bit. Ok. That's the tibia. Ok. Yep. On, pull it up into extension. And so it's not as bad with this trial, but with the real thing, you really got to do that. So, here you got the secondary Impactor. Nope, that's it. He's got it and then we'll need the slap hammer afterward. Ok. Make sure it's down. It's a pretty good fit even for a trial. Punch it. Ok. Now, the real thing, so with the real thing, it's really important to do that, that pulling in deflection thing, let me see. A get this little bit of stuff off here. Even this little stuff here will kind of keep it from going down. Another thing I do is I take a little bit of bone and shove it down in that hole. Usually if you are doing a cemented application that will be filled with cement, so I take my cham for cuts and shut it down in that hole. Ok? So here's the implant again. So you can, you guys can't see. But if I just put this on, I'm in flex and I can tell by, by the, by the holes I put in. So it's got to get pulled up out of flexion and now it can go in. Now, here's what I like to do. I like to put it part of the way in. Take this thing off. Thank God, I like to put the polly in at this point to kind of guide it and then I bring it into a little bit of extension. Ok. And now, so now it's kind of sort of guiding it back. Bring it into about 90 I line this thing up with these little, uh, holders on the side, the little, um, whatever you call, those divots on the side of the implant and they're pretty solid, hits much more solid than your cemented surgeons will be used to this dead blow mallet helps. So, let me see if I can show. So I'll tell you sometimes in, in a, in real bone, if it's pretty hard, the champers will engage before the distal, before the distal surface will engage and sometimes the distal most part will not engage at all. So sometimes right here, there'll be a gap. The champers will both be down, the anterior part will be down the post, but the most distal part won't settle all the way down to the bone. And that's perfectly ok because it's a wedge fit. So sometimes if they see that and they get stressed out about this distal most cut not being on bone, that's OK. The feel is really good. The instruments, they're pretty sweet. It's pretty good. It's a, I mean, it's awesome. All right. So let's see. Put this sucker back on. All right. Go for it. Can you see get the one, hold on. The key is rotational stability. This is, this is the key and it's not moving front back, it's not moving, pulling it straight out that this is a, it's a non issue.
