Knee Pain With Exercise SURPRISING CAUSE and HOW TO FIX IT
What's up, guysé Jeff Cavaliere, ATHLEANX.COM. Let's talk today about knee pain. If you've been lifting for any length of time,likely you've had some sort of knee pain or might have knee pain in the future if you'renot doing the right things. Guys, knee pain can debilitate your leg workouts.I know. I've suffered from it, and I know what it can do to your legs when you're tryingto squat and especially squat heavy. So, what I want to do today is first of allcover a couple of the reasons what might be causing your knee pain
because that's going to be important to understandthe difference, and then show you one that I think is really common especially for guysthat train and lift weights. So, if we look here, we've got our boy Raymond,and we've got our skeleton, so what you'll see is that in the knee we've got a lot ofdifferent sources of pain. Now you guys have probably heard about ACLpain and MCL pain and LCL, right. Well we're talking about tears really because those are ligaments that get injuredsports most often. The ACL and PCL are inside the knee.
The LCL and MCL are going to be on the insideand outside of the knee, and basically, that's just one source of injury but we've also gotosteoarthritic changes that can happen where you actually get degenerative changeson the bone, the bone on bone area, or on the underside of the patella here that grindsup against the femur. We could talk about that in a second. We alsohave meniscus issues. Guys talk about that. It's the cushion between the two bones here,the tibia and the femur, that gives us that space between the jointthat can wear down or tear. But I find that the most common injury that we get when wetrain,
our inflammatory conditions from overuse ofthe patellar tendon. So, the patellar tendon, this is what you're seeing right here,ok. And what it does is, it runs over the patella,here it holds it in place, and you can get inflammation of this a lot of times causingpatellofemoral issues, we've heard that before, and it impacts thetracking of the patella when your knee goes into flexion extension. So, as we flex the knee and extend the knee,you want normal mechanics of the patella so you get this glide.
And it glides right in this groove right here.You can see that it's supposed to glide right in this groove. But what will happen is, it starts to getout of position. Well, guess whaté This isn't a knee issue. I've talked about this before,this is not a knee issue. The knee is a train, and this is its track.Here, and here. So guess what happens when the track gets twistedé The knee in the train goes flying off thetrack. So, when you start looking and focusing all your efforts on the knee pain and tryingto, you know, cure the patellofemoral issues,
or try to cure your patellar tendonitis, andyou're not paying any attention to the track, you're way off track. So, what you want to do is, you want to startlooking for the source and the cause of your knee pain because most often, 99 percent ofthe time, the source of that is going to be somewhereelse. And when we look at this, it's either going to be the track at the bottom, whichis going to be controlled by your ankle and foot, or, the track at the top which is going tobe caused by, or controlled by the muscles
Why Do Joints Pop And Crack
Are you readyé cracks knuckles Ah I've been cracking my knuckles since I can remember. And I do it so often that I've been called quot;crunchyquot; I've gotten so good at it that I can pop almost every joint in my body. But like, why do they do thaté 'Cause even though it feels awesome It does sound rather alarming.
Well, a joint is just where two bones in your body come together. But they don't actually touch. Because if they did the friction would grind them into a bone powder Which I think most people would find unpleasant. So instead your bones are capped by cushions or articular cartilage Which are kept lubricated by thick, clear, mucusy stuff called synovial fluid. And that fluid is produced by the synovial membrane, which surrounds the entire joint. When you stretch or bend a joint those bones pull away from each other. And that causes the synovial membrane to stretch.
Which increases the amount of space inside it, in turn lowering the pressure. And this is important because your synovial fluid is full of dissolved gasses Mostly carbon dioxide and oxygen. And when the pressure of a fluid drops any gasses trapped within it become less soluble. Basically, they undissolve and this means they form bubbles. So that pop you hear is actually the sound of a bubble forming inside your synovial fluid. What's really cool, is if you take an Xray of a joint right after cracking it you can actually see the bubble. It increases the size of the joint cavity by about 15%
And it takes about 20 to 30 minutes for that gas to dissolve back into the fluid. Which is why you generally can't crack the same joint over and over again. There's weirdly not a lot of data on whether knuckle popping is dangerous. But a named Donald Unger was awarded an IG Nobel Prize in 2009 For habitually popping the joints on his left hand but not his right, over the course of 60 years. His left hand didn't develop any issues. It's not super hardcore peer reviewed science. But it's still pretty interesting. So, while knuckle popping doesn't appear to cause arthritis, it apparently can lead to weaker grip strength.
This might be the result of stretching out your synovial membrane or your tendons. The most dangerous part of cracking your joints is probably that people nearby don't always find the noise enjoyable.
