You’ve seen him do it a thousand times. Every night on Inside the NBA, Kenny "The Jet" Smith makes that iconic, frantic dash from the desk to the giant video board. Shaq is usually wheezing with laughter, and Charles Barkley is tossing out some legendary insult about how Kenny runs like he’s trying to keep his pants from falling down. But if you look closely at his stride, something stands out. His knees practically kiss each other while his ankles stay wide apart.
It’s called genu valgum. Most people just call them knock knees.
Honestly, it’s one of the most talked-about physical quirks in sports broadcasting. Fans on X (formerly Twitter) and Reddit post clips of his gait constantly, wondering how a guy with that specific leg alignment managed to win two NBA championships and play a decade at the highest level. Usually, we associate elite athleticism with "perfect" biomechanics. Kenny Smith is the living, breathing rebuttal to that idea.
The Reality of Kenny Smith Knock Knees
Let's get the medical part out of the way. Genu valgum isn't some mysterious curse. It's a condition where the knees tilt inward, creating a gap between the ankles when the knees are touching. For most kids, this is a normal phase of growing up. Their legs look a bit wonky around age three or four, and then they straighten out by seven or eight.
Kenny’s didn’t. Or, more accurately, his professional life made them much, much worse.
When you spend ten years as a starting point guard in the NBA, you aren't just running; you're exploding. You're cutting, jumping, and landing with thousands of pounds of force on your joints. For Kenny Smith, who relied on speed (hence the nickname "The Jet"), that wear and tear was localized. Because of his natural alignment, the pressure wasn't distributed evenly across his knee joints. It was hammered into the outer compartments.
A Career Built on "Bad" Knees
It is a minor miracle that Smith played 737 regular-season games. Think about that. He wasn't just a bench warmer; he was a key piece of the Houston Rockets’ "Clutch City" era. In the 1995 Finals, he hit seven three-pointers in a single game. You don't do that if your legs are "broken."
However, the cost was high. By the time he retired in 1997, his knees were essentially "shot." He’s been very open about the fact that he has almost no cartilage left. When you see him run to that screen today, you aren't seeing a healthy 60-year-old. You're seeing a man who has undergone multiple surgeries—including arthroscopic procedures to clean out debris—just to keep moving.
Why Do They Look So Different Now?
If you watch old highlights from his time at North Carolina or his rookie year with the Sacramento Kings, his knock knees aren't nearly as pronounced. They were there, sure, but they didn't have that "collapsing" look.
What changed? Years of compensation.
When one part of the knee wears down, the body shifts. It tries to find a path of least resistance. For Kenny, that meant his gait became increasingly "valgus-dominant." His adductors (inner thigh muscles) became the primary drivers, pulling his knees inward even further.
There's a specific clip that went viral a few years back where an influencer named FamousLos poked fun at Kenny’s walk. Kenny’s response was classic: "You still can't guard me!" He’s right, of course. But the clip also highlighted just how much the condition has progressed. His knees don't just point in; they seem to "lock" at an angle that looks painful to the average viewer.
The "Inside the NBA" Roast Factor
The show wouldn't be the same without the constant ribbing. Shaq often mentions "matchstick knees" or "bird legs." In 2022, Shaq even shoved Kenny into a Christmas tree during their race to the board, a moment that nearly ended in a medical emergency given the state of Kenny’s joints.
But there’s a deeper layer to the jokes. The crew knows how much pain he’s actually in. Charles Barkley has had his own share of hip and knee replacements. They’re all members of the "Limping Legends" club. When they laugh at Kenny Smith’s knock knees, it’s a form of locker-room camaraderie. It’s acknowledging the "bill" they all had to pay for their fame.
Managing Genu Valgum in Adulthood
So, what does someone like Kenny do to keep from needing a wheelchair? It’s not just about surgery. In fact, full knee replacements are often the last resort because the recovery is brutal for former athletes with so much scar tissue.
- Physical Therapy is Non-Negotiable: Kenny has mentioned in interviews that he has to stay active just to keep the joints lubricated. If he stops moving, they "rust" shut.
- Weight Management: Every extra pound is four pounds of pressure on the knee. Kenny has stayed remarkably lean since his playing days, which is likely why he can still "sprint" at all.
- Orthotics: You’ll notice Kenny rarely wears flat shoes. He needs specific arch support to try and realign his feet, which in turn takes a tiny bit of the inward pressure off his knees.
What Most People Get Wrong
The biggest misconception is that Kenny Smith has "weak" knees. It’s actually the opposite. To play at his level with that alignment, his connective tissue and stabilizing muscles had to be incredibly strong. He wasn't playing despite his knees; he was playing with a body that had adapted to a specific mechanical "flaw" and turned it into a weapon of speed.
Another myth? That he’s "crippled." While the gait looks alarming, Kenny is still active. He coaches, he travels, and he stays on his feet for hours during broadcasts. He’s managed a chronic condition for thirty years without letting it sideline his career.
Key Takeaways for Longevity
If you struggle with knee alignment or the start of "knock knee" symptoms as you age, Kenny’s journey offers some real-world lessons.
- Don't ignore the gait. If your knees are turning in, your hips and ankles are taking the hit too. Strengthening your glutes and abductors can help pull those knees back into a neutral position.
- Impact matters. Kenny’s knees were destroyed by hardwood. If you have genu valgum, stick to low-impact cardio like cycling or swimming.
- Move or lose it. Synovial fluid (the stuff that lubes your joints) only moves when you do.
Kenny Smith’s knock knees might be the butt of a thousand jokes on TNT, but they’re also a badge of honor. They represent 10 years of elite competition and a lifetime of staying in the game. Next time you see him racing Shaq to the big screen, don't just laugh at the walk—appreciate the fact that he's still running at all.
To get a better handle on your own joint health, you might want to look into biomechanical gait analysis. Most high-end physical therapy clinics offer this; they use cameras to track exactly how your knees load when you walk. It's the best way to catch alignment issues before they turn into the kind of "bone-on-bone" reality that Kenny deals with every day.
