Yeah,

and I'm really, really important to get that messaging right and hopefully change some of the misperception out there that's in the community. Now, for these injuries, why do they matter? What are the consequences of tearing your ACL? When does that, when do those consequences tend to happen?

I suppose initially it's, you can't play sports for a period of time. And that can be, as I said, with my brother, that can be really mentally challenging, as well as not being active and, you know, the risk of putting on weight, et cetera, and it becomes a bit of a vicious cycle. And that's obviously in the short term, you know, it's a period of time when you're on the sidelines, and you're really isolated in terms of going through a rehabilitation program. It's often boring. You're doing the same strength exercises in the gym, and that's, I think, a real skill of a physio therapist or a rehabilitation specialist is to make it really interesting. And I say to patients, let's get your knee bigger and better than it was before you injured it initially, because you injured it, because maybe you weren't strong enough. So let's actually take the opportunity to to get it bigger and better. And I think work on performance aspects during that rehabilitation period and for a young sports person, I can see that they're the time maybe focused on also improving that performance when they can get back to sport is really valuable. So nine to 12 months is a typical time period until someone can return to that high level sort of impact pivoting and twisting type sports. But unfortunately, for about 50% of people, they aren't able to get back to their same competitive sport level. And they often complain that it's because of their needs. Sometimes it's life and they've got kids and they change jobs and they don't want to play sport anymore. And that's fine. But often it is because of their knee. And we know that about one in three people report ongoing pain and symptoms in their knee, you know, up to five or six years after their ACL reconstruction. So it's certainly not a self limiting condition that sort of you have a reconstruction, you do a bit of a very habit. It's back to a normal name. Unfortunately, once you have an ACL injury, it's probably not ever going to be a normal knee. Again, the biomechanics change ever so slightly with a reconstruction. It's never 100% that native knee that you had, but you were given when you were born, unfortunately. But more sort of longer term beyond the sort of inability for some people to return to sport and physical activity. The big one, obviously the elephant in the room is the development of osteoarthritis, ongoing symptoms that come with that. And I'm a researcher perspective, it's really challenging to work out what are the, where's the transition from painful following your injury to then when the pain develops or starts because of the osteoarthritis in your knee. And we're doing some work in that space at the moment as well. But we know that about 50% of people within five to 10 years following their ACL injury, irrespective of whether you have a reconstruction or a rehabilitation only, will ultimately develop osteoarthritis in their ACL injury. And this is much higher rate compared to their other knee, for example, that hasn't had an ACL injury or other type of injury and much higher than their uninjured peers that team mates who have played the same sport for a number of years, but having had an ACL injury. So this can be quite debilitating for patients and your point earlier around highlighting that these are 25 and 30 year olds who are often having these ACL injuries. So they're in their 30s and 40s when they're developing osteoarthritis and developing these symptoms. So it's often the peak time of their employment, they've done their careers from a professional point of view. They're often having kids, so caring responsibilities, ability to play with your kids is at the forefront of that last stage as well. And as we know, as I'm sure many of you guessed on the podcast have described and discussed, is that there's no QA Prostereal Thrius once we have an alignment. And so it's really about how do we manage the long term health of this knee, which we should be doing during initial stages of rehabilitation, which we'll probably get to. But it's appreciating that your knee is at risk and doing everything we can to try and improve or optimize the health of that knee longer term. We also know that unfortunately there's a bit foretold high risk of having a knee replacement when you're before you're 60 if you have an ACL injury. So there's some of the facts and figures which I think we're talking to patients about it's a real challenge because you don't want to create all this fear and worry about something that might happen in the future because 50%, 60% will actually be okay and not develop arthritis too quickly. So they might not be in that group. But I think it's also important to give a realistic understanding of and a motivation for them to do their right hat because as we'll talk about it in a minute, I'm sure there are some things we can do during rehabilitation, which we hope can help reduce that risk as well in the long term.
