Is Your Knee Predicting the Weather? The Real Reason Your Knees Ache

Dr. Greg has heard it from patients for years. And in this episode, he breaks down why joints seem to sense weather changes — and what that sensitivity is actually telling you about what's going on in your body.

There is a real connection between barometric pressure and joint discomfort, especially in people with osteoarthritis or existing tissue damage. When atmospheric pressure drops before a storm, it can influence the fluid and nerve sensitivity inside a joint, lowering the threshold at which pain is perceived.

But here's what's important to understand: the weather isn't causing the problem. It's revealing one.

If a joint is already irritated or sensitized, environmental shifts can amplify how aware you are of it. And people tend to move less when the weather is bad — which leads to stiffness, reduced circulation, and more discomfort on its own. The weather becomes a magnifying glass for something that was already there.

For most people under forty who are active and working out regularly, arthritis isn't the issue. What Dr. Greg sees constantly — and treats every single week — is anterior knee pain.

This includes patellofemoral pain syndrome, which sounds complicated but comes down to a straightforward problem: the cartilage between your kneecap and your femur is getting irritated because of how load is being distributed through the joint.

The three most common culprits he identifies:

Hip mobility. If your hip can't rotate the way it needs to, your squat mechanics break down and more force goes straight into the knee.

Hip strength. When the glutes aren't doing their job, the femur shifts inward or outward during movement. That creates a torsion through the joint and throws off how the kneecap tracks against the femur.

Quad flexibility. Your rectus femoris runs directly over your kneecap and connects to your shin bone. When it's tight, it's constantly pressing the kneecap into the femur — and that pressure adds up fast.

This is the part that surprises most people. When someone comes in with anterior knee pain, Dr. Greg often won't touch the knee directly for several visits. The treatment is almost entirely focused on the hip — and sometimes the foot and ankle.

The knee is a hinge joint. It's designed to flex and extend. It sits between the hip and the ankle, both of which are meant to be highly mobile. When either of those joints isn't doing its job, the knee absorbs the excess force. It becomes the middle of a tug of war it was never supposed to be in.

Fix the hip. Relieve the quad. Change the mechanics. That's how anterior knee pain actually gets resolved — not by treating the knee.

Even people who are active, working out consistently, and doing everything right can run into trouble if their movement patterns are working against them. Dr. Greg sees it regularly with crossfitters, runners, and gym-goers who have great coaches but have never had someone pull them aside and walk through the specifics of their individual mechanics.

A common example: during a squat or lunge, keeping the chest upright and letting the knee drive forward puts excessive shear force through the patellofemoral joint. A simple shift toward more of a hinge pattern — chest coming forward, hips going back, less knee travel — dramatically reduces that load and starts recruiting the glutes the way they're supposed to be working.

The goal isn't to change how you work out. It's to change how load is being distributed so that no single joint is taking on more than its share.

If your knee hurts going down stairs, during squats, during lunges, or after a run, that's not something you manage. That's something you fix.

The earlier you address it, the simpler the solution. Catch it early and a few targeted exercises — quad foam rolling, glute activation, some hip mobility work — can make a significant difference in just a couple of weeks. Let it go too long and you're dealing with compensations layered on top of compensations.

And if you've been to physical therapy before and felt like you just did generic exercises without anyone really explaining why — that's worth addressing too.

Your knee isn't predicting the weather. It's exposing a problem that was already there. And for most active people, that problem lives in the hip — not the knee.

📍 If your knee hurts with activity and you're ready to actually fix it, book a discovery call or schedule an evaluation at movement.com. Dr. Greg will walk you through a full movement assessment and give you a specific plan — not a generic protocol.
