Full-on spring mode. Road and MTB.
You should put some road tires on that MTB and keep it on the pavement. Not only are you much less likely to come off on the road but the pedaling cadence is gonna be way more smooth and predictable which seems like what you want with that knee right now. I don't generally dole out medical advice on the interwebz but that seems like a no-brainer.
I blew out my knee 25 years ago. Got it scoped but never got the ACL fixed. Cycling is the only reason I can still ski - lots of docs have confirmed that over the years. Xrays show that it's loaded with arthritis but it still works and it's pain free. Ride that friggin' thing like you stole it!
This is the set-up I have on my mountain bike, Giant Iguana, makes a great road bike for big guys like us, more rugged than a true road bike. It's a hardtail, more suitable for the street than a full suspension. Put some Michelin's on mine, they roll pretty good on pavement, fairly high pressure, 80lbs, I believe. Good luck with your recovery Camp, be patient, it'll never be good as new, but close enough. Sounds like you're progressing fine.
