I have read through this thread including your responses to requested information. I don't think noticing more numbness or having some swelling at 9+ months is out of the ordinary. I also agree that the resistance level on the elliptical and bike are not difficult. I don't think your time is excessive, but this is not muscle enhancing work.
I actually do this for weight loss, to burn calories. About 4 years ago I was 291 pounds heavier than I am now. So exercising is a huge part of my life now. I feel if I don't continue to exercise I will go back to my old ways. Yes I agree it's not difficult or excessive. I need to keep limber and I am not trying to build excessive muscles. Just want to be in shape.
I didn't see any reference to cadence or speed. Maybe you are going too fast? In any case, I think you would help build muscle strength better by trading higher resistance for lower speed on the elliptical although a gradual transition is probably safer. Biking, maybe the same, but it really depends on a lot of factors so I'm unsure there. The only other issue is: Are the machines you are using completely stable? Unstable fitness machines can cause injury to anyone.
Some good points here. Cadence is about 50 watts on Rower, 70 Speed on Elliptical, Bike is 4 minutes sitting and 1 minute standing on spinning bike and most of the time I use a recumbent bike and just do approx. 60 watts... Nothing crazy, a little faster than a good clip. I have commercial equipment, very stable.
Rowing, depending on your flexion, does take the knee into much deeper flexion than the bike (which is deeper than the elliptical). Rowing on a good machine, like a Concept2, is a great, smooth full body workout, but I would check with your doc and PT on their thoughts.
In fact I do have a concept2 rower. I have checked with my doctor and have been doing all these exercises for 6 months believe it or not. I was on my bike 2 weeks after surgery. I only did 3 revolutions but my PT made me do the work. That's after going down 10 steps to the basement.
Assuming mechanical issues are nonexistent, and it sounds like you will be having X-Rays to check, the one thing you mentioned that I would address is the "looser" feel. I would get with your PT. The looser feel could be remedied by strengthening any imbalances. Sometimes less is better as some have suggested. Sometimes different is better. Good and stronger muscle support is usually beneficial.
So I am happy to say I have no mechanical issues, I have been using ice, elevating. I believe your correct, I am spending to much time doing the same old thing. I need to mix it up and build muscle to stop the looseness or thumping. All I have to do is figure out what I need to do. I could go back to my PT days and do all that stuff over again but I think I need more or different. If anyone has any ideas please pass them along.
Best wishes.
