Hi,
I can tell you that you didnt rupture your patella tendon because you wouldnt be able to bend your knee in the slightest. It would be physically impossible. What you mostly likely did is tear it. Since a significant amount of time has past, I would go to your OP right away so avoid permanent and long term issues with your knee as you age.
Surgery isnt so bad. I too was terrified of going under for the first time but unless you have someone is your family who has had an adverse reaction to going under, you have nothing to worry about.
Best of luck and go get that knee checked out right away...for your sons sake. He needs you with a good knee for years to come!
