There's honestly not a ton of difference in 18-30 yr old recovery time in elite athletes. I'll be completely honest too, you're a tad naive if you don't think a lot of the professional athletes aren't getting (ahem) some help in their recovery time as well. The severity of the tear and complexity of the repair have far more to do with recovery than the difference between an 18 and 30 yr old, when we are talking about pro athletes. It's also a lot different for a 6'10" basketball player than a 5'8" baseball (or wrestler or even football player). One of the biggest hurdles to get over is the stress test of jumping and landing on the repaired leg. Simple physics will tell you there's far more stress on a player JQs size, than say a short wrestler (who, btw, doesn't jump). IIRC, JQs was a complete tear with the MCL, PCL, and meniscus still in place. That's as clean as it gets, but still you're looking at 99ish % of the elite basketball players of the world taking AT LEAST 8-9 months to get back on the court.
