Now I understand why I need to stay controlled with my operated knee and not jump back into intense sports during Month 3 - 9 post op. Thank you!
My doctor advised me not to do the jump till the whole complete year.
Mans thinks i read at the speed of light
Skateboard P hahahaha
This was fast!
Agreed. Seems like good info, but way too fast!
Dylan P I hear ya
Hahahaha😂
most research papers indicate the ACL actually becomes stronger in most cases than the original intact one.
Most statements claiming to disprove something are backed up with some kind of sources or facts. I say "most" facetiously as it would be completely retarded to cite "most" of anything without knowing how many of said items are in existence, research papers for example.
@@jamesmclaren4 There was no claim of disproving anything. Might want to work on the reading comprehension.
@@dustinstout1798 You are right brother. The information out there supports what you say. You do not have to sit here and post a bunch of sites you found. Your quick statement is helpful to anyone who really wants to look it up.
There is nothing stronger than your original part of your body.
@@bossjdcoc3569 probably right, people are built differently, some better than others, have diferent health activities, age might play a role. My coworker and I had the same acl surgery, after 4 weeks, he was walking w out crutches normally, I am not there yet. We have similar genetics and are same age, and I am more hansome than he is, go figure. We are all different and our recoveries are different, even w same surgeon.
Please make more videos to explain the whole process in detail.
These "facts" are arguable. Saying the graft never reaches the strength of a real acl when most studies show the reconstructed acl is actually 220% stronger than a natural acl when placed and during the ligamentization loses 50% of its original strength (leaving the new graft at 110% the strength of a real acl) means this statement should be taken with a grain of salt to say the least.
How about you back these claims up with some sources Chris or shut ya bitch mouth.
You do realize anyone can google the information and see the strength of each graft before and after ligamentization right? :)
chris biker can’t believe u made him mad by stating some facts
@@jamesmclaren4 I can back chris s claim as im a 4 time recon clients 3 left 1 right past 24 yrs my firat failed when I was young stupid after 3mths played sport tore it .my 2nd lasted from 1999 to 2011 had a fall from.ladder and stretched the graft so they decided to do a third with lars ligament and so far 8 yrs on left knee feels great stronger than ever before im.older ofcourse but still massive active its about 3 times stronger with lars ligament. My R knee recent done may was due to spikes in shoes grabbing on turf and not releasing and tore acl mcl and lcl. R leg always stronger leg ive had a itb graft and lars this one. I look fwd to playing sport again march 2020. But as a guide normal allograft is about x2 stronger after full recovery with a lars (synthetic overlay) its about 3 or 4. Hope that helps mate p.s have had patella tendon hanstring graft x2 and itb once
Inspirational guy👍👍👍
I read that after complete healing a patellar graft can reach 112% strength
CORRECT
sir muje jo screw dala h uska ghav ab tk nhi bhar rha h one month s Jada ho gya to uske side effect h kya
Half the video is blank..
where am I looking?
I’m extremely perplexed by these knee dynamics.
So, as per surgeons, there is enough blood flow for a graft to remold itself but not enough blood flow to even repair a partially torn ACL?
Someone please make me understand😢
Good one😅
Very easy to understand. It's a complete money racket. Search for Kieran Richardson regarding ACL rehab. He's trying to lift the lid on this whole racket.
Acl grafts are stronge than original . The only issue is that grafts are elastic and thus get streched and some times get elongated.
Stretched graft = surgery. Where did you get that wisdom from?
NO, DE HECHO LOS TENDONES SON MAS RIGIDOS QUE LOS LIGAMENTOS, CUANDO UNA LIGAMENTOPLASTIA, TIENE PROBLEMAS ES QUE O SE ROMPE O SE ENLONGA , EN TODO CASO , MUCHAS VECES CUANDO SE ENLONGA ALCABO DE UNOS MESES VUELVE A SU ESTADO NORMAL SIEMPRE Y CUANDO ESTE EN EL PROCESO DE LIGAMENTIZACION OSEA DE 3 A 12 MESES , DESPUES DE ESO SUPONGO QUE SERIA CIRUJIA , EL PUNTO ESTA EN QUE LA GENTE SE APRESURA CON LA REHABILITACION
Guyz i dont know which graft is used in my reconstruction. How could i know without asking my surgeon. But i can assure that. The graft is not patella tendon. I thinks it will be either hamstring tendon or an artificial implant. Any one help me to find which one is this.
Do you feel tightness at your hamstring?
It will be your semi tendenosis and gurilas like I had you will have if its left side a scar below the knee and about 8 staples long coming across that's were it's taken from
@@dzulaimin2473 yes I feel same like some hard object is at the back of thigh and it doesn't allow the movement of leg . can u tell mw why it is happening ?
WTF? Your surgeon didn't tell you??
Is there any stability lost in the medial side of knee?? In between healing days .
Mohit where you got operated?
Depends if u have any secondary injuries MCL LCL strains tears when u did initial injury . But if I follow rehab protocol correct u shouldnt have any issues
@@gawaink2600What protocol are you using?
Am I right in concluding that because a new graft grows back, the option of autograft: hamstring or patella and allograft, doesn't really matter? Because they all die anyway?
well not exactly. some will hold up more than others. i had acl and both meniscus repair on december 6, 2016 and i used the patella, which is the strongest and more long term. my guess is that depending on which graft you get, the different tendons are made slightly different and would "die" more gradually or less gradually and tear less easier. and to figure out which type of graft you'll get you need to tribute what all activity you'll do, if you plan on going back to sports like i am then the patella is highly recommended, because it is the strongest and less likely to retear.
What happened to your knee? sports?
my takeaway from the video was that the chosen graft eventually dies away and is replaced by our cells which form the new graft.
That's why i concluded that the the graft decision isn't that important. Maybe i'm wrong? i hope not, ... because on Feb 8th i had the ACL done using a cadaver graft.
Also because of how i injured it, a bad clash of knee's playing sports, it didn't matter if my ACL was reinforced with iron rope, it was getting blown out either way, knew straight away it had popped.
yeah thats kinda how mine happened too. i was at soccer practice at school and i was in defense and a girl was offsides behind me and i turned to get the incoming ball and she was running at it too and we hit at a t kinda shape and her knee just slammed into mine and i collapsed to the ground with several pops. it dislocated my knee and tore everything up. i didnt know what happened cause i had previously never heard of an acl or really any knee injuries before.
how are you feeling after your surgery??? i know i was down for a while after mine and pt freaking hurt the first few times. but hey, im like 9 weeks ish maybe 10 out and im walking pretty much with no limp and no brace so trust me, as hard as it seems in the beginning, just follow what your physical therapists says as gospel and youll do great!!
the graft isnt much of issue, like i said it mainly just fits around your specific needs for after surgery. i dont know much about the cadaver because i immediately excluded it as a possibility for the rare chance that my body rejected it. and the entire graft doesnt necessarily all die away just bits and pieces, kinda like if you get a scrape on your knee and it scabs over kinda deal, little gaps will die off or become weaker and your body will fill it in and "scab it over" but the original graft that you get would keep its strength for the most part and its durability
@@gaybunnyalert7297 how are you know?
Is ACL LET reconstruction surgery good in the long run?
Hamstring autograft(graft from own body) taken for ACL replacement will be restore/recover ever ? If it so how long it takes.
The strength returns much faster than the hamstring regrowth. I have seen studies that suggest 7 out of 10 people regrow the hamstring. The regrown hamstring has scar tissue and the strength of that part has not been tested against what would be normal.... but the rest of your hamstring makes up that strength way before that point in most cases. Some people do have prolonged hamstring weakness.
No it will never be the same. 15 years post surgery here. Still significantly weaker and the hamstring is deformed. Have a couple of friends that did the same surgery and it's the same for them.
Does reconstructed ACL serve for life, say 50 years after surgery it is still good and strong?
Yes it lasts a lifetime. You should consider it as your regular acl.
Is this for internal graft or for fibrecraft
Can’t read that fast
I got infection after 2 months post acl reconstruction surgery my doctor removed screws but graft retained in acl debridement / cleaning Surgery is thier any chance to return to sport without further surgery
How u got to know u got infection??
@@nikhilpatil1333 did u face the same issue??
@@vamsisrikanthrallabandi7015 no
Was it fibretap internal brace surgery?
@@raysguitar8507 no
I had a surgery on my torn ACL in right knee 3 months ago but sometimes it pains and pops 🤔 why it is so
kk thanks a lot
aftr 1 yr what is the condition.
How are you now???
surgeon said its scar tissue and should go away over time! I am also just over the 3 month mark and have that sensation sometimes. Keep doing physio and break through the scar tissue! You will be ok!
@@RainVine omg I feel the same thing too. It has been 2 months since my surgery.
I had surgery on a torn ACL in my right knee about 3 months ago with a patellar tendon graft. Does anybody know if using a patellar graft weakens the patellar tendon, making injury to the patellar tendon more likely when I eventually return to full activity?
how u doin now?
It will increase risk. They cut a 1/3 of your patellar tendon off.
That portion of your tendon will grow back during the time your recovering from
Ur ACL injury. Muscles are very vascularized
Its better to get it from your hamstring because a portion of it will regrow and you won't really feel a difference. I personally know someone who had a patellar graft and they are in pain after sport. They basically use rehab to help out with the patellar deficiency and have fully recovered from the acl injury. Sucks that they traded one issue for another.
You could ask your orthopedic surgeon right?
this video no sound, or my laptop speaker not working
video was quite hard to follow through.
Nothing there after 2:49.
As per this video sprained ACL or Minor Tear Should also recover on its own.
I think it's hidden from us by medical society or they don't know it still...
One logic is if tron acl doesn't heal... How come it gronw from our young age till here... There is something missing in medical society about this I guess
Body reacts differently from what i've read. The graft triggers an immune response that causes partial necrosis but more importantly grants blood flow that allows for cellularremodeling , which is where the real healing takes place. As in the video.
A partial tear doesn't bring the same response from the body, as the ACL has no blood flow the body doesn't recognize that something needs to be healed.
Is there like an injection there that helps ligament repair.
In and out.
No anesthesia except maybe localised.
Maybe bpc-157 peptides. Banned by sports organisation. It really helps. Mostly for your rehab to speed up everything. Also boosts muscle regeneration.
Hello all this video is some what right in theory but not very well explained I have had 3 recons on left knee over last 24 yrs and just recent R knee . had patella tendon hamstring tendom and hamstring with lars ligament for third Left knee and ITB and lars ligament for my current R knee recon. patella tendon graft you will get tendonitis and a small caved in area from where bone was taken infront of knee .but shouldn't get any obvious issues long term. as for recovery yes the graft dies in sense but then restablishes its blood supply as shown in video and same time the grat grows into the bone tunnel with screws aswell taking fortabone collagen powder 12mg a day will help the recovery in this process. 8 to 12 weeks graft at its weakest dangerous re rupture point. even though knee may feel good don't run or jog. 3 to 6 mth continue calf raise single leg squats bridging exercises . do hydrotherapy in heated pool or normal pool wading side to side abduction exercises water resistance is great also with pool aids around 4 mths then increase hamstring exercises no weight no thera bands should be passive movements.6to 8mths job in straight lines no side to side movement this is ofcourse for everyday person nt sports person as they are afforded more physio professionals and science methods to assist.. but as a guide 10mths post surgery if you been doing your rehab good if you play sport the knee will almost be at full strength about 2.5x stronger than original graft and f you have a lars synthetic ligament aswell its about 4 xs stronger patience is the key and you will get aches pains niggle along the way just manage them and if I doubt see your specialist and discuss concerns
I had my hamstring graft replace my acl. How much stronger is it?
@@matthewelliott52 if U give the rehab and graft regrowth sufficient time and also muscle strength very important . Probably 12 to 18 mths later should be around 1.5 to double strength of original graft . Quite interesting almost as if having ACL recon is a good thing lol .just stay focused not lazy on recovery and exercises etc give 1half yrs to almost back to normal if doing sports etc 18mths is a good time frame
I'm not over weight and have involved in sports as hobby and wanted to continue that . Heard patella tandon graft will be more strength and longer . Can you please suggest your view on this
@@gawaink2600 I never heard anyone suggest to return to sports as late as 18 months, some athletes make a full return in 6, but generally in 9 months
@@adels.185 I wrote 10 months did you not read. At the end of my post above . If your just an average.sports person. Not as conditioned as high level then you can afford the extra months to rebuild muscle mass lost. .heavy weight post 7 months . My sports physician stated a guide every day muscle wastage. Loss needs. At least 2 or 3 days to rebuild. . Thanks for your comment however
what about the screws and staples used to hold the graft in position?
Very nice animation, it helped me understand a lot.
I was asking, what happens to the screws and staples used to hold the graft in position?
I also got my ACL torn in my right knee last month. And I'm thinking instead of getting operated i should work towards making my muscles strong.
My meniscus was damaged a little bit but doctor said it will heal with rest but ACL will require reconstruction surgery.
ajay singh get the surgery and use a patellar tendon graft. If you wait the knee will only get worse and everything else will too. The patellar tendon is a perfect choice for a speedy recovery and is stronger than a normal ACL. This video lies about the strength of the graft. It's been proven that the patellar tendon graft is way stronger than a normal ACL as long as you use a graft from your own body. The other options are fine too but the hamstring and quad tendon are kinda risky because they can stretch like all muscles can they are tough too but that's the only problem with those. I've had the surgery before. And my knee is better and tougher than ever. Remember to use your own graft don't use a cadaver. You will be fine best wishes to you
ajay singh there are only screws for the patellar tendon graft and those dissolve away and help promote bone growth. The other grafts require staples because they don't have bone ends
kadie louviere why not use a cadaver??
this is craft allograft or autograft
Both act as same
Akash Jaiswal but allograft weaker
Akash Jaiswal there is no prove for that
You sped up the texts to light speed then left nearly 2.5 minutes of video blank? Logic? Also, from anecdotal evidence as well as literature, your new acl should actually be a bit stronger than your old one. A friend of mine jokingly told me he wishes his uninjured knee would get hurt just so that he can have the same stability he has in his grafted leg haha.
It depends on the graft. Patella is a bit stronger but has its downsizes as well. Rehab is longer, more painful and there might be other problems with big scar or with pain in the knee. Hamstring is the best but also requires 2 ligaments. It weakens the knee at takes about 1 year to be approximately the same strenght as original one.
Cant read the text. Too dark!!
im screwed cause i got a cadaver, achilles tendon...not the strongest choice of graft but i was not awaree
sara aguilar you have dead people parts in your body.... you are a monster and should be ashamed
Vicente Valtieri you're weird as hell
LOL.. don't scare her! You're the monster....hahaha
You are not screwed, yes it is the weakest choice but failure rates of cadaver (allografts) are generally very high in people under 25 years old. If you are older and not into cutting and piviting sports you might be better off with less donor site morbility
You're not screwed Sara; donor allografts used to have a higher rate of failure due to the irradiation process used to sterilize them.This irradiation process is no longer used today, and subsequent rates of failure have decreased accordingly. Because of the lack of donor site morbidity (the additional injury you would have elsewhere if you harvested a tendon from yourself to use as the ACL graft), you feel better/healed/stronger faster than you would if you had an additional harvest site injury. This is why the rate of failure is higher in younger patients who opt for an allograft: they feel great before the graft has a chance to heal properly, so they push too hard, too soon. The failure rate of an acl donor graft (allograft) in patients above 25, using non-irradiated donor tissue, is roughly equal to the others, because the patients are older and more patient. Far and away, though, the rate of success of an acl reconstruction is linked to the skill of your surgeon, and whether you opted for the graft that that surgeon is best at/most comfortable doing. I deliberately chose to have a tibial allograft from a donor because I didn't want to damage more of my body trying to fix my ACL. I am happy with my choice, and if you're reading this, I hope that you're recovered and doing well too.
