No surgery for now.
The ACL that was replaced last May is frayed, not totally torn. But it IS stretched out.
Miniscus that was repaired last May is also torn again.
Doc fitted me with a custom permanent brace so I shouldn't have to worry about it going out on me, and is sending me to physical therapy.
I check back with her in 6 weeks via phone, then in 3 months to see if I am happy or not.
If not, then I have to have a whole new ACL put in.
