His knee isn't injured. He's growing.
If your son is between 10 and 15, plays basketball, and his knee hurts, read this.

His knee isn't injured. It's being tugged on
Between 10 and 15, bones grow faster than muscles. The thigh gets tight and pulls on one spot.
Not the joint. Just below the kneecap, on the tendon. A spot that has not hardened yet, about the size of a coin.
Every jump. Steps are the worst. He is landing on that spot and braking with it at the same time. That is why he limps to the car after practice.

Almost nobody with it knows it has a name
It is called Osgood-Schlatter. 1 in 10 young basketball players has it, and most parents never hear the words until a doctor says them out loud.
On you, where the tendon attaches to the shin is solid bone. On him, it is still a growth plate. Several times his body weight lands on it every time he comes down.
SEE WHAT TAKES THE PULL OFF IT
He said he was fine. Then he limped to the car
That is how most parents find out. Not with a diagnosis, with a walk across a parking lot.
He will not tell you it hurts, because telling you means sitting out. So he plays through it and you watch him push off the door frame to get into the back seat.
So why hasn't anything worked? None of it was aimed at that spot. A sleeve squeezes the whole knee. Ice just numbs it. Advil goes to his head, not his knee.

Your doctor mentioned a strap. He didn't tell you which one, or where it goes
That is the gap almost every parent falls into. The diagnosis is right, the recommendation is right, and then you are on Amazon looking at 100 identical black straps at 10pm.
Osgood-Schlatter does not care about the strap. It cares where it sits.
Between the bottom of the kneecap and the bump on the shin. Never on the bump. 9 parents out of 10 put it too low and then decide straps do not work.
This one was developed over 4 years with orthopedic surgeons, it weighs 48 grams, and it ships with a placement card.

What other parents wrote

“The doctor said patellar strap and left me to figure out which one. This one sits exactly where he showed me. Mason plays the full game now instead of sitting out the fourth quarter.”

“He is 12 and every adult strap we tried slid down by halftime. This one has two tabs so we tighten each side. It has not moved once in six weeks of practice.”

“He used to limp to the car after games and I hated watching it. Three weeks in, he walks out normally. He puts it on himself now, I do not even have to ask.”

“He actually wears it, which is the whole battle. It looks like gear, not like a medical brace.”

“I still have the bump at 42. Nobody gave me anything like this when I was his age. Glad he has it.”

“12 of the 18 boys on their team had the bump at the same time. Coach keeps two spares in his bag now.”

“My son said it feels like his knee is being held up instead of squeezed. That is exactly the difference.”

“Works well, but be honest with yourself about the first two weeks. He complained every single day before he got used to it. Now he puts it on without being asked.”
