That's amazing. How soon after surgery did you "start training again". I began to introduce very light impact once per week at 4-1/2 months and then heavy at about 5-1/2 months...much to the chagrin of many on this site I'm sure.

Actually, I started training at 6wks post op. Swimming & biking outside. I don't like biking indoors but I did just a little for ROM exercise. I was outside every opportunity the weather gave though. Swimming very easy at first, then built up to my normal 1mi regimen about 1 month after that. Biking was very easy as well. No hills and kept to about 20mi at a time. Since biking is non-impact, I was a little more aggressive, but still didn't get out of the saddle for about 3.5 months. Now, I'm out of the saddle w/o any problem. Running was much less aggressive and I only ran with a true front strike so as to cushion my stride instead of jarring my new pieces/parts. I ran 4mi two days ago and can still feel it a bit in the muscles but I just rest a couple days and take it easy and it gets stronger. I usually don't run any less than 5K when I run. Running pace started out at 11 and now I'm at 9:30 - 8:30/mi. I try to listen to my body and back off rather than push through at this point.
Although, now that I'm at the 6 month mark, I'm picking it up a little. I'm aware that healing is still taking place, so I'm not moving ahead with fear, just trying to move ahead with wisdom. I am in the gym lifting weights, but I don't do any leg presses. I did in the beginning 6-12 weeks with an empty sled just to get the ROM of my knee to my shoulder. Worked out fine. Hope this helps.
