My knee clicking syndrome?

I am not seeking medical advice and I am not suffering pain.

I am wondering if what I am experiencing is common or just my old rusty body?

Every time I start driving it takes about 30 uses of the clutch for a sensation of pressure to build up in my left knee, easily relieved by straightening my leg which creates a loud click from the joint. The weird part is that no matter how long my journey I won’t get that sensation again, it’s a one off each time I drive. Next journey same again, no difference if I have been out of the car for 5 minutes or 5 hours. I have had this for about 2 years now.

are common, and usually nothing to worry about.

A clicking knee can be caused by a small amount of gas gas moving from your synovial joint capsule when you put the knee under tension. A fold in the synovial tissue in your knee (called a plica) can cause the click, but that is normally associated with some discomfort.

As long as you get no pain or swelling you almost certainly have no cause to worry, but if you're concerned you could always ask your GP to examine the knee.

I have those same symptoms, and the same stretch is required to ease the discomfort. I glad that it's not just me deteriorating as I type.

But, "I have had this for about 2 years now.", I wouldn't make a habit of waiting two years before getting any ailments investigated.

Do ( did ) your Mum and or Dad have similar problems ?

Ehlers-Danlos syndrome (EDS) (also known as "Cutis hyperelastica") is a group of inherited connective tissue disorders, caused by a defect in the synthesis of collagen (a protein in connective tissue). The collagen in connective tissue helps tissues to resist deformation (decreases its elasticity). In the skin, muscles, ligaments, blood vessels etc.

Joints are held together and in place by connective tissues & ligaments. The joints are surrounded by a thick, clear liquid called synovial fluid, . When you stretch or bend your eg finger to pop the knuckle, you are causing the bones of the joint to pull apart. As they do, the connective tissue capsule that surrounds the joint is stretched. By stretching this capsule, you increase its volume and with an increase in volume comes a decrease in pressure. So as the pressure of the synovial fluid drops, gases dissolved in the fluid become less soluble, forming bubbles through a process called cavitation. When the joint is stretched far enough, the pressure in the capsule drops so low that these bubbles burst, producing the pop that we associate with knuckle cracking.

If I were you get your GP to check it out.

always had knees that click a lot never given it a second thought till i saw your post, click loudest when standing up from a chair.

Neither of my parents have joint problems, both in their eighties. As I stated before there is no pain associated with this, just a sensation.

Quickbeam, thanks, not just me then.

Not by a long chalk. Almost every human being has or will experience the 'gas pop' I mentioned when synovial capsules are tensioned. It's almost always nothing to worry about, unless it's accompanied by pain.

Other animals experience the phenomenon. I once heard a loud click when my dog jumped up to go for a walk. She heard it, and jumped in surprise.

When I run up stairs between my ankles and knees I sound like someone walking over bubble wrap

You have stairs between your ankles and knees...?

The mind boggles. No chance of you sneaking up on anyone then?

Not what I'd imagined you'd thought of....
