Not my knees, but a mate recently had one done & had the same concerns.
His physio made sure he did his recovery exercises & didn't rush back to riding for the first 10 weeks.
After that, he just took it easy on the 1st rides until he knew that the strength was there. Don't be too concerned 
The world won't end & your leg won't fall off either
Good luck with it
