Crunching sound in knee
« on: December 29, 2014, 07:59:38 AM »
Hi,

I've been diagnosed with chondromalacia several times and I have a very ugly noise in my right knee when I straighten it from 90 degrees bent position. It is like something crunches inside my knee. Why does it happen? What is making that noise and do you know how can I get rid of it? Thanks.

You might find some useful information in here  http://www.kneeguru.co.uk/KNEEnotes/primers/patella-primer

Does it hurt when it crunches?  If so, you might want to talk to your specialist about hyaluronic acid injections to lubricate and cushion the joint

No, it doesn't hurt but I think if I repeat it like 15-20 times I get inflammation above the kneecap, around the quadriceps tendon. I don't know if it has anything to do with that sound though.

Noises can have multiple causes, and don't bother to ask a doctor because the explanations are always vague and uncertain... among the ones I heard are:

1) Irregularities in cartilage cause noises when sliding. If bone on bone, much more.

2) With inflammation you tend to over-produce fluids - effusion (not of the best quality) and gas, which increase the noises as well.

3) This one is a personal observation: when I had my joint with more inflammation I would also notice more noise, right or wrongly, I was associating it with less capability of the muscles and tendons to keep things tight... but that was just an impression.

Why would you do it 15-20 times if you know it causes inflammation?!  ???  Better to do nothing that aggravates the knee if you have knee issues!

Hi, I had patella alta, trochlea dysplasia, patellofemoral chondropathy and maltracking all which was causing a loud crunching noise (only to be described as getting a packet of crisps and crushing them up) when walking up and downstairs, and when straightening leg, a popping when going from standing to sitting.
I've recently undergone surgery (mpfl reconstruction, Ttt, chondroplasty to patella and Microfracture)
I was told by os that maltracking was causing crunching and pop was due to a peice of cartledge behind my knee cap catching when sitting to standing.
For a year a had fluid build up just above knee cap and in mpfl region which was there to try and protect the inside from further trauma.
I was told the only way to try and get rid of the crunching was to line everything up to were it should be with surgery but they could not say for definate that this would stop the crutching, I'm now 14 weeks post op and as far as I can tell it has improved things lot, but I'm not yet back to walking up/down stairs properly.
For me surgery was the only way to do anything with the crunching but I know everyone's different sometimes strengthing quads without doing exercises that cause discomfort is enough to help with this issue. Hope you get this issue sorted :)

I am not doing it. I tested it few times and stop it afterwards.
