Knee Exam: Lachman Test

[DrDoomPool]

While the negative comments below are unnecessary, they do bring up an interesting debate. Physical examination is a crucial component to an orthopedic diagnosis. It would be a mistake to send every patient that has had a joint injury to get an MRI as they are extremely expensive. Also a seemingly significant MRI could be completely asymptomatic. This physical exam directly assess the function of the ACL, which is a critical step in determining the direction of the medical intervention.

wtf is a DO

[DrDoomPool]

@allvo1 Doctor of Osteopathy. A medical physician just like a MD, but Osteopaths are also trained in physical adjustments/alignments.

[allvo1]

@DrDoomPool Oh, so you mean a chiropractor?

[saemi3000]

I'm pretty sure this is a legit test, my anatomy teacher is an orthopedic surgeon and has done this dozens of times and taught us this the day before yesterday. But no tests are perfect and my guess is that for those of you who had an ACL injury but a negative lachman test, the test was not done properly or that the ACL wasn't torn enough for the doctor to spot the injury.

[telj1]

I'm not a Dr. but I don't think....scratched that, I KNOW for a fact my Knees would be worse of after this test. My knee just cringed as I watched this. Hurt my knee a week ago and thinks an acl type deal. I'm a head over to Kaiser and get that mri...

[barnns11]

@telj1 you are a retard

[telj1]

@barnns11 I'm a retard because I had an honest opinion on how I feel...??? C'mon, you can do better than..."you're a retard".... Go drink a pissed laced milkshake.

[barnns11]

you have serious problems dude. wake up to yourself. Your comments are that stupid it actually sad to think there are people like you out there. Have a nice life.

[barnns11]

@telj1 good one dude.

[barnns11]

@telj1 you seriously are retarded though, how does it make it worse ?

[telj1]

@barnns11 In this time and age and advancement in tech/medicine, you would settle for this primitive test? If the answer is yes then we have nothing else to discuss. Peace and good luck!

[barnns11]

@telj1 So you want to MRI everyone with a sore knee ?? wtf are you talking about ?

[telj1]

@barnns11 No.... I want you to leave me the hell alone and go see the different methods of diagnosis for this injury. Don't engage in a discussion leaving your half ass comment when it's obvious you don't know jack sh8t. SMH @ this idiot!!! lol bring it!

[TheCrazy243]

I have appt in 2 weeks .aghh!! It gonna be hurt a lot. I torn my acl last month n I'm 14 yrs old.

[nantesagents14]

if anyone has any time and insight, im really curious as to whether i have torn my acl or not.

i have an appointment for an x ray monday and i am getting an mri soon.

my doctor did none of this and was very vague when i asked her if my acl was tore.

she told me that your knee would "hurt and feel unstable."

i'm not trained in the medical field but being an athlete, almost all injuries involve being hurt and feeling unstable.

I'm very anxious to find out whether i have an acl injury or not.

My Lachman test was negative but I was still scheduled for an MRI to check for meniscus damage and it revealed that my ACL was torn as well. So it's always good to get a 2nd opinion.

[simersimersimer]

@Foolanna lachman test can be negative sometimes and still you can have acl tear,,so its always better to get mri done.

[Foolanna]

@simersimersimer

Exactly, the Lachman test on my knee was negative for 2 months after the accident. First because the knee was a bit locked due to the torn meniscus and then because of the swelling. So only after the meniscus surgery and after the pain was gone, the knee started to be instable. MRIs are expensive but crucial. It's been 8 months now and I just finished my last round of ACL-physiotherapy even though I still have some problems running and swimming - knee injuries are tricky!

[theartofbone]

I find that saying bending the knee 20-30 degrees is more confusing than saying bending the knee 150-160 degrees. It all has to do w/ what planes you use for reference, however, isnt it easier to use the natural flexion as reference?? VS using extension (extending an imaginary line along the thigh's axis, and using that + the lower leg's extension as the angle of reference?? Seems to me using the flexion method is easier to picture (the flexing of the knee as vertex). I hope im clear.

thanks

[blazers1987]

@theartofbone

Correct anatomical postion is with the leg extended, so that is why 20-30 degrees is used instead of the angle formed by the leg and the thigh. Also, in case you have never had anatomy, "thigh" is above the knee, and leg is below. Using the term 'leg" to refer to the appendage as a whole is not technically correct. Hope this helps.

[magd791]

this test would hurt so much if u have raptured ur ACL. Thank u for the video :)

[johnrp99johnrp99]

This test is painless. I have had two ACL ruptures and this test never hurt me.

[twoods1122]

I agree... If you make it through the tear, everything else seems pretty painless...

[Fridz1986]

@magd791  in my experience no. no pain at all.

[Bobbysboy]

@magd791 it doesn't hurt when they do this test. I tore my ACL last year and they did this.

[drfax1]
