Let me pile on to something rgold said. The recovery rate depends on your body, and none of us can generalize what you will do. That said, I suffered my accident when I was 60, and my physical therapists said my recovery was faster than anyone else's they'd seen at any age. Unfortunately (or so it seemed at the time), that didn't prevent my orthopod from keeping me earthbound for the recommended nine months. Still, the quite rapid healing enabled me to get in better overall shape while I was waiting to get off the ground.
Since you've been keeping fit, your recovery may also be quicker than "normal." Hang in there, do what you must, and let us know how it turns out. You have a lot of us on ST rooting for you.
When I was 25, I ripped my right knee to shreds and had to take off 7 months from any serious physical activity.
Just after surgery I was laying in the recovery room feeling sorry for myself and thinking about how much I'd be missing.
I asked the guy in the next bed what he was in for.
He smiled and told me it was his third hip replacement in as many years. He had rheumatoid arthritis and was given a %50 chance of seeing his 20th year. He was 17 years old.
Meeting him was a life changing experience for me and when I think of him I am grateful for all that life has given me.
Good luck with your procedures Anita. I had surgery on my achilles to repair a rupture mid June of 2013. By September I was back on my bike and was posting faster times (I'm a Strava junkie) within a month. I'm sure I was overly amped and that helped. While no procedures are the same and I'm not fully familiar with the procedure you've described, I think as a general rule you should be back in full form shortly after the projected time line expressed by your Ortho and PT. Hang in there, it gets better. Focus in on getting past the surgery part and getting on with the healing part. Good luck and report back!
