What’s That Horrible Crunching Noise In My Knee?
So here I am, sitting in the study of the Southern Command Post, reviewing emails. And I came across one from a nice lady who is very concerned because she has knee pain, she is very heavy, given her size and worst of all, she has noises inside her joints that can actually be heard by people around her.
She was quite properly concerned because she’d like to get rid of her knee pain, and she wanted to get a copy of my newest healing program, HOW TO AVOID KNEE SURGERY (which you can get here at this link: http://drbillsclinic.com/avoid_knee_surgery.html ), but she was afraid that it was already far too late for her–that the noise in her knees meant that all the cartilage had worn away completely, and that she had a “bone-on-bone” condition. This is what we in the trade call an “end stage knee.”
When articular cartilage, that normally coats the joint surfaces, is so diseased that it has eroded away and exposed the underlying bone, the naked bony surfaces grind upon each other with a deep, hard grinding sound and sensation that, once experienced or heard, is difficult to mistake for anything else.
It really is like rubbing two big rocks together, with grinding, rubbing and at times a mechanical ratcheting sensation. And, since the bone is where all the nerves reside, it hurts like hell! And that doesn’t count the extra pain from the inflamed lining membrane (synovium) that adds its own component to the pain.
So whether it’s osteoarthritis or rheumatoid arthritis, it’s at this end stage of disease, with exposed, bare bone, when major surgery IS truly indicated. Because at this state of the art, at this time, we cannot yet regrow new, healthy articular cartilage in a totally arthritic joint. The best we can offer is total knee replacements. And when they are indicated, they can be wonderful: pain relief, restoration of function and correction of deformity, with good to excellent results in over 95% of cases.
BUT…it’s major league surgery, with lots of risks and potential complications. So you don’t do it if you don’t HAVE to.
However, all noise from within the joint doesn’t necessarily mean that your joints are finished and you need major surgery. Other conditions can cause noise, as well. When the lining of the joint becomes inflamed and swollen, its folds become thickened and enlarged. They rub upon each other, making a finer, more delicate crunching that we call crepitus or crepitation.
If the membrane is restored to normal, the inflammation resolved, the swollen folds stop rubbing together and the noise stops. But if the condition persists for a long time, the membranous folds may become replaced with fibrous tissue (they become bands of scar tissue) and they then must be cut away surgically, to eliminate the sensation and the sound.
Then, there is degeneration of the articular cartilage surfaces, which may break apart into shredded beds of cartilage fronds, appearing like areas of “crab meat.” When these fragmented or fibrillated regions rub, one upon another, they too produce a crunching sensation, like walking in a gravel pit.
This condition is called chondromalacia (“soft cartilage” grade III) and once this point has been reached, where there is physical disruption of the cartilage surface, it can never again return to a pristine, smooth surface. I discuss this disease and the various types of arthritis in my LITTLE GREEN BOOK FOR ELIMINATING KNEE PAIN (manual and CD). Get it here at: http://drbillsclinic.com/eliminate_knee_pain.html However, even though the knee is noisy, it doesn’t mean that it will immediately go on to full end stage arthritis. The knee can stabilize in this state for a long time, sometimes pain-free (if a little noisy), if treated with the exercises I teach in my PAIN-FREE PROGRAM. See what I mean at this link: http://drbillsclinic.com/exercise_eliminate.html
The point is, this lady has nothing to lose and everything to gain by at least trying all the conservative measures that are available, to relieve knee pain. One of them, or some combination of them, may give her the knee pain relief she seeks, and buy time, until she can lose weight and make an eventual surgery safer and more likely successful.
So the next time someone, maybe you, says, “Hey, what’s that horrible crunching noise in my knee?” now you know what some of the reasons might be. And some may well be treatable by non-surgical measures, like those in HOW TO AVOID KNEE SURGERY: http://drbillsclinic.com/avoid_knee_surgery.html Noise doesn’t necessarily mean it’s the end of the line, or that a total knee is the only option.
Til next time, my friend, be well.
Yours for a pain-free tomorrow,
Dr. Bill

hi, my knee has been bad for year and a half now, sore all the time . I can’t flex my quad, while laying with the leg straight, without getting this tightness and wierd movement at the back medial part of knee. When i’m standing and leg is straight, if I flex leg i get same thing with what feels like something moves funny, like crunching in there.anyway i got an mri which was normal except some increased signal in that area( actually stated as mensci there), but not strict criteria for tear-it stated.Initially something popped from a big guy jumping on my back while i was bent over on bad knee, didn’t hurt and felt funny but after a month and a half i was back to activity and one night after jumping alot at a show it has been messed up like this since. thanks

I would like to tell others about your post so I went ahead and posted a bookmark on Digg.com using the name of your blog and the post title. I hope that’s OK. My email list would like to read this post as well I’m sure.

Hi I’m 28 years old and I have constant grinding and crunching sounds in both knees, one more than the other. I have had both my knees reconstructed when I was 18 with what they called the “Houser Procedure”. Apparently I was knock knee’d, opposite of bow legged. Anyways, I recently went to a Orthopedic surgeon to gain further information on what the possibility of me having knee replacement surgery and he flat out told NO, that I was too young, that and I was too heavy. Well I have recently lost 20 lbs, and am taking Osteo Bi-flex that was recommended. I have yet to feel any improvement from this so called remedy. I am in constant pain with the grinding, stairs absolutely kill me going up and or down them, I can’t enjoy playing with my 7 yr old daughter like I wish I could. If there is anything that you can consult me with I would greatly appreciate it, even if it requires me having surgery I will that’s how desperate I am to get the pain away. I can’t swim without my knee caps popping out of place, walking is painful, and exercise is out of the question because of the strain on my knees. I recently saw a documentary on the news about knee cartilage trasplant and was wondering if there are any places in the state of Texas that do that and I could be a canidate for it. Thanks for your time!

Hi Karla,
Sorry to hear of your constant patellofemoral pain. You probably have severe arthritis behind your kneecap
and probably on the adjacent femoral trochlea, as well. This is a very tough problem. There ARE now patello-
femoral joint replacements, but at 28, you really are too young. Nothing made by Man will last a half century,
which you can expect to live. You may benefit from an additional procedure, or ultimately patellectomies
(surgiocal removal of the kneecaps, with reconstruction of the quadriceps tendons). You need a bona fide
knee specialist, not a garden variety orthopaedic surgeon. Best bet is to visit the closest University
affiliated hospital, since that’s where most of the “big guns” hang out. There are also braces that can
help to support your kneecaps and discourage dislocation. And of course, constant exercise to overdevelop
the VMO muscle, to pull the kneecaps inward. Good luck! It ain’t an easy problem.
Best wishes,
Dr. Bill

By all means, Ruthanne. Thank you for your interest and support. I appreciate your confidence in me.

Hi Michael,
Sounds like either a tear in the posterior horn of the meniscus (which can still
exist, even though the MRI was equivocal–they are only 90-95% accurate on the medial
side of the knee, not 100%), or a torn popliteus tendon. You should see an orthpod
for evaluation/treatment. If he/she recommends exercise, try my PAIN-FREE PROGRAM
at http://drbillsclinic.com/exercise_eliminate.html/.
Good luck!
Dr. Bill
