Most people think of a knee injury as a knee problem. You tear something, you rehab it, you move on. But the science tells a very different story — one where a single traumatic injury quietly drives cartilage degradation, cardiovascular impairment, and systemic inflammation for decades after the initial damage has "healed."

I got a firsthand look at this when an MRI revealed two meniscus tears, a split MCL, and early-onset osteoarthritis in my left knee. That last one was humbling. I always assumed osteoarthritis happened to other people — older, less active people. Not someone who squats heavy and trains consistently.

In this episode, Forrest Smith — CEO and Co-founder of Kineon Labs, a health technology company specializing in targeted red light and laser therapy devices — returns for his third appearance on the podcast. And the picture he paints of what happens inside an injured joint long after the rehab is over is sobering.

For example, the NFL tracked over 3,500 players who'd returned to competition after knee injuries and found chronic inflammation still present 10 to 20 years later, despite world-class rehab.

Notably, the quads on the players' injured side ran one to two degrees colder, a sign of impaired cardiovascular delivery. And the risk of major cardiovascular events jumped by 50% – not because of the original injury, but because of inflammation that never resolved.

That's the cycle most people don't know they're stuck in. And it's where laser-based photobiomodulation changes the equation. Targeted 808nm lasers can drop inflammatory markers like TNF-alpha and IL-6 by 70 to 85% within days.

Once that chronic degradation slows down, chondroblasts — the fast-growing front end of cartilage — can actually proliferate and begin rebuilding the extracellular matrix. Slow the destruction on one side, accelerate the biology on the other. That's what "regrowing cartilage" actually means.

Penetration depth is what makes lasers fundamentally different from LEDs. At five to seven centimeters of reach, you're dosing 10 to 100 times more tissue volume than a surface-level panel can touch.

Then there's the other side of this that almost nobody talks about: the ibuprofen your doctor hands you after surgery. Research shows that 90 days of use increases heart attack risk by 48%, heart failure by 35%, and major coronary events by 75% — while actively impairing the collagen and fibroblast function your body needs to heal. It's doing the exact opposite of what most people assume.

If you've ever dealt with a joint injury, chronic inflammation, or just assumed over-the-counter painkillers were harmless, this one's worth your time.

A lifelong athlete and CrossFit enthusiast, he founded Kineon after developing a portable, medical-grade laser device to treat his own chronic knee pain.
