deformed leg after molt

Hi guys, I was wondering if you could help me out
My male a.geniculata just had his maturing molt, but he seems to have had an issue with his leg not hardening properly and its now deformed and bent and he seems to be having trouble moving it, and he can't regrow it as he's mature now, I was just wondering what the best thing to do in this situation would be?

If it's too much of a problem, he might remove the leg on his own.

If he can still walk around and eat, he'll be good to go. The only issue that comes to mind that if you want to breed him, and it's in the first pair of legs, he might have some difficulty. Outside of that, he'll be as good as gold.
