Well, it's 72 hours after my knee replacement surgery and I'm still trying to get the pain under control. Lots of swelling and bruising. I keep telling myself this is only temporary but am not having a lot of luck believing it LOL.
Whatever you do, listen to the physical therapist.
Granted you know your physical abilities better than the PT person but please listen.
There was a late 40's-early 50's lady on my local forum that had both knees done at the same time so her riding time wouldn't have a double interruption. That was 18 months - two years ago.
This lady trail rides ---- over the river and thru the woods, not easy hacks thru a Metro park.
She got back in the saddle before the PT felt she was ready. Even bought those swivel stirrups to help her knees stay a little more mobile.
Last I heard, the rumor was she had to have knee surgery again. I don't know if it involved both knees but one is bad enough.
The moral of that story: While you're going to be pushing yourself so you can get back in the saddle, don't push yourself beyond what is reasonable for your body.
We're not spring chickens and no matter how we fight it, we just don't bounce back as fast or as good as we used to
The last thing you want is for the surgery to have been a success but not be successful because you tried to do too much too soon
