"Athletes who do return to their preinjury levels are at higher risk for a second ACL injury, compared to those who do not return or have no history of ACL injury."
Where'd you read that? I feel like the way healthcare is these days some of these rebuilt ACLs may end up being stronger than the real thing but I can also be talking out of my ass.
In either case end of the day knee injuries are more about luck than repaired vs normal ACL. Get bent back a certain way with your foot in the ground and unless it's made of titanium it's likely getting injured.
We just need Jimmy to be smart when he's moving. Think long term. If it's not the SB then live to play another down/game. Though honestly I'd rather see Jimmy running very little.

"Second ACL injuries six times more likely after reconstruction, study finds"
I question these types of studies when it comes to evaluating extreme athletes in the prime of their careers. The study looked at people 10-25 years old, 59 female to 19 male and 47 control people...who knows what female/male ratio.
It also said females were twice as likely to suffer a knee injury on the OTHER knee...how does that make sense?
"Overall, 29.5% of athletes suffered a second ACL injury within 24 months of returning to activity with 20.5% sustaining an opposite leg injury and 9.0% incurring graft re-tear injury on the same leg. A higher proportion of females (23.7%) suffered an opposite leg injury compared to males (10.5%)."
NFL athletes aren't comparable to regular joes, even if they're "athletes" certainly don't compare to females.
Who performed their surgery? Who did their rehab? How did they rehab?
Now if they do a study on NFL players then we're talking.
NFL players suffered 219 ACL injuries between 2010 and 2013. Forty players (18.3%) had a history of previous ACL injury, with 27 (12.3%) retears and 16 (7.3%) tears contralateral to a previous ACL injury. Five players (2.28%) suffered their third ACL tear. Receivers (wide receivers and tight ends) and backs (linebackers, fullbacks, and halfbacks) had significantly greater injury risk than the rest of the NFL players, while perimeter linemen (defensive ends and offensive tackles) had significantly lower injury risk than the rest of the players. Interior linemen (offensive guards, centers, and defensive tackles) had significantly greater injury risk compared with perimeter linemen. ACL injury rates per team games played were 0.050 for grass and 0.053 for turf fields (P > .05).
Conclusion:
In this retrospective epidemiological study of ACL tears in NFL players, retears and ACL tears contralateral to a previously torn ACL constituted a substantial portion (18.3%) of total ACL injuries. The significant majority of ACL injuries in players with a history of previous ACL injury were retears. Skilled offensive players and linebackers had the greatest injury risk, and significantly more ACL tears occurred among interior linemen than perimeter linemen. The month of August had the highest incidence of ACL injuries, probably because of expanded roster sizes at that point in the NFL season.

Where are you posting this from? Maybe it's how it comes up for me on the iPad but it definitely wasn't part of the article posted earlier.
To me 12.3% is a pretty small sample size especially given the nature of the game.

It's actually 18.3 % if you include the contralateral knee .
Considering the NFL most likely is not made up of 18.3 % of the players who have had an ACL tear before .... it suggests that players with a history have a higher rate of injury to ACL
The original question was , is there a higher risk for ACL tear with a history of ACL tear?

"NFL players suffered 219 ACL injuries between 2010 and 2013. Forty players (18.3%) had a history of previous ACL injury"
Out of 219 injuries 40 were to guys who had ACL injuries prior if I'm reading that correct. That means 81.7% of injuries are to guys without that injury history.
All that tells us is the sport is violent and injuries happen if you're in a bad spot. Maybe I'm tired and my brain isn't working but how can they make the claim that ACL injuries in NFL are more likely to guys who had those injuries before when 80% did not have prior ACL injuries?

"NFL players suffered 219 ACL injuries between 2010 and 2013. Forty players (18.3%) had a history of previous ACL injury"
Out of 219 injuries 40 were to guys who had ACL injuries prior if I'm reading that correct. That means 81.7% of injuries are to guys without that injury history.
All that tells us is the sport is violent and injuries happen if you're in a bad spot. Maybe I'm tired and my brain isn't working but how can they make the claim that ACL injuries in NFL are more likely to guys who had those injuries before when 80% did not have prior ACL injuries?
If the percentage of total NFL players that have had a prior ACL tear is significantly lower than 18.3%, then it is relevant that the percentage climbs amongst those who have just suffered a torn ACL. That implies that players who have a prior ACL tear are more likely to suffer a torn ACL than players that do not have that history.
It does not mean that players that have had a prior ACL injury are likely to tear their ACL again though. Only that they have a greater chance than those who have never torn their ACL.
Originally posted by Phoenix49ers:Originally posted by blizzuntz:We demonstrate that reinjuries comprise a substantial portion of total ACL injuries among NFL athletes, as 12.3% of total ACL injuries occurred in a previously reconstructed knee and significantly more retears than contralateral tears occurred among players with a history of previous ACL injury. This indicates that it is possible that the risk of suffering a knee injury may be greater in elite athletes returning from ACL reconstruction than it is in elite players with a native knee.
"It is possible"
"May be"
Not exactly definitive.
Would also be helpful to break it down further to how many of those were contact vs non-contact.

I've been watching the NFL for a very long time like many of you. If there was confidence that players who've had major injuries prior to be drafted was insignificant, you'd see a lot more players with injuries being drafted at the same rates as least or never injured players. Until I see a draft where player x doesn't drop 4 rounds or go undrafted "because of his medical" I'll believe it.

They don't drop due to fear of reinjury. They drop due to fear of where they're at once they're healed.
Not all ACL injuries are created equal. You have partial ACL tears and you have your Marcus Lattimore type injuries which are complete career enders or two year rehab types.
It's very obvious that if all else is equal you want the player with 0 injury history. We've seen plenty of cases where guys rehab ACL injuries and come back great - Adrian Peterson is the perfect example. I'm STILL floored by what he was able to do. Those were some terrific roids he took to rehab and come back the way he did.
The reason guys drop in the draft is the unknown factor. You have no idea what the player will be post rehab. That's why Nick Bosa's ACL injury in HS isn't a big deal to me...we've seen him post rehab from that injury. But when guys get hurt you never know the mental part of it, you never know how the body actually recovers. Some guys don't have the mental fortitude to come back strong from that type of injury. It's because of that they drop in the draft.

How long does the claim of "injury prone" or the "risk is higher" to re-injured an ACL remain relevant for some?
So if Gore tears his ACL this yr is it because he tore his ACL (2x) 10+ yrs ago? Keenan Allen tore his ACL in 2016 and hasn't missed a game in two yrs...is he still more likely to re-tear his ACL?
