Well, the posted video helps on reminding that these incidents (speaks only on Nurkic one, but such things apply to many different cases) have physical explanations (biomechanic related) based on the forces aplied, angles, speed, weight...
I'd add that now we have way more advanced medicine, nutrition, phisio, etc, than in the past (captain obvious) and thankfully so. So not only at basketball, but at every sports all over the globe the athletes work harder (or better saying, work way more methodically for advanced results) on taking it to the next level, and that even on youth levels. That makes sports nowadays been played at faster pace and bigger athleticism. That's basically increased load in many aspects, body weight, vertical jump, landing speed, distance covered, accumulated load, etc...
Also worths note that injuries now, even as ****ed up as it can be, not necesseraly means career ending (or not being able to play at top level), as we have better procediments for surgery and recovery. There's too more info on how to prevent them, like preventive exercise programs, posture correction or even preventive procedures (like a minor surgery to avoid a future bigger problem). So it's more treated as "controled/calculated risk", even when the protocols are lame. Like in soccer, where the lack of a proper clear and incisive concussion protocol combined to increased levels of head clashs creates a situation where fifa (and every others big soccer organizations bodies) is literally waiting for the worse to happen before getting it right.
