Yeah, so welcome. So I'm really happy to be here. My topic today is prior isolated meniscus surgery significantly increases the risk of future ipsilateral ACL ligament reconstruction up to five years. No disclosures. Just a little outline. Just a little bit about me. I'm PGY-4 at Yale and a hopeful future sports fellow. So going through the process now. So a little bit of background. I mean meniscus tears in the young population often occur from traumatic rotational mechanism of injury. A lot of the research looking at the relationship between ACL and meniscus has been more so after you have an ACL reconstruction, what is the risk of getting a meniscus tear? So our question was, how about the other way around? How about if you had a meniscus tear first, what's your risk of getting an ACL reconstruction after? So the purpose, twofold, investigate the timing, incidents, and risk of subsequent ipsilateral ACL and then also to define the incidents of surgically treated isolated bucket handle meniscus tears. So it's a pearl diver study. The kind of take-home things that I think are important using Pearl Diver, you really have to hone in on how you get your data. So what we were doing, we basically use CPT codes for first-time meniscus surgery and then we match that with ICD-10 codes so that we were sure that we were getting the same side of the knee. So we're matching right and right and left and left, which I think is a valuable thing with Pearl Diver. Just the exclusion criteria and typical statistical analysis. So overall there's over 106,000 meniscus surgeries and this is just kind of a nice pie chart just kind of showing. Majority of them obviously are meniscectomies and then repairs are on the other side. And then this, you know, a lot of numbers but I think the important thing to take away from this is obviously the younger age patients, 10 to 20, that's most of the patients that are going under the repair. Meniscectomies are the older, you know, 30 to 40. And then this is just the pie chart for bucket handle surgery, which was 1.67 for an incidence. And then this is just a breakdown of medial and lateral for bucket handle. So the unique thing that we did was we basically made a benchmark first-time incidence of patients going having ACL and Pearl Diver had 500,000 patients. And we found it to be 0.2%. So that's just the general population that we picked. And then this is kind of a busy slide and things I want to focus on though is, so if you underwent a prior meniscus repair, so bucket handle repair, non-bucket handle is all meniscus. And then we broke it down to be medial because we found that to be the most significant. So if you had a medial, prior medial bucket handle tear, your risk was significantly elevated to undergo a future ipsilateral ACL injury. And then same thing looking at meniscectomy as well. And then this is just the timing using Kaplan-Meier that just shows that medial bucket handle repair is actually you're at future risk of getting a ipsilateral ACL injury. So conclusion, the present study found isolated bucket handle meniscus tears to be 1.67. So it's a, you know, really rare event to occur. And the other thing was identified potentially having a prior isolated meniscus surgery repair or meniscectomy as a potential risk factor for subsequent ipsilateral ACL reconstruction. And thank you.
