That's a tough break for your son, Kingtut. Positively no pun intended! Surely he is disappointed in missing the Archery finals.
Several years ago, I had what's called a boxers break. Not real sure what surgery could do for a knuckle though. Doc told me, they'd have to do an outpatient thing and set/splint it. At the appointment, was given option for getting knocked out, opted not to... thought it couldn't be as bad as the action that caused the break. WRONG! Though it didn't last to long, seemed like the doc was pushing me to get another busted knuckle on my good hand! No ill effects with the knuckle to this day, it's just flat and looks kinda odd.
What was the worst of the deal, working in maintenance at a chicken plant and had to pull light duty for three weeks afterwards... Finks stuck me in the parts department. Longest three weeks of my life! Two weeks out of that, broke my nose when a two foot spanner wrench slipped. That'll get your attention. lol If you were eating KFC some 9 10 years ago, sure hope you enjoyed it.
Anyhow, hope your son is feeling better... or soon will. As for surgery, it won't be necessary IMO but you, the misses and your son may feel differently after talking with the surgeon.
Here's to a speedy recovery for the young master... !
