Finndog, your rehab work sounds pretty close to what I am doing. I will stress the quad issue, those nice strong well tuned machines just lay there when you say "move" right after surgery. One of the most helpless feelings I've ever had, laugh and cry over the issue at the same time. But they slowly come back, just keep working at the pt and especially the home excercises they give you.
I just passed week ten and have been stationary bike riding at home and at pt for about 8 of those weeks. Balance board is cool. even before I was hurt I was never very good. Ham curls and leg presses are the fun weight machines for the quads. They just started me on an elastic band around my ankles, I talk sideways steps against teh elastic, this one is making me sweat a little.
I see the doctor on the 24th (day short of 12 weeks) and have been told if all is good I will be out on road bike at that time. No mtn. bike stuff yet. I keep saying ski in august or september but reality probably says no (but hey I can be a bit delusional if I want). I figure if no harm happens I should be in pretty good shape come late November for next season.
I also had some pain after a long walk that I had checked out with the doc pretty plainly before hand. We have a nice park that has about 2 miles (4 round trip) of flat smooth blacktop road that is closed for walking and doc said that would not be a problem. I did the hike and about half way back (agreed, you turn around but you still have the entire distance to go back) felt a little pain in the knee. The PT folks I am seeing have mentioned that this can be due to the patella (learning to re-track movements that it used to know). Anyway the walk was not strenous but the most walking I have done in quite a while so a little ache and pain might have been expected. I worry whenever there are sharp shooting pains of which I have not had any yet. All things considered I plan on another walk, too much fun and finally outside. probably will walk half the road and try to turn around there see how that does.
It sounds like forever to heal but like time in general, going by faster and faster.
