I was able to do the recumbent bike about 10 days. My spin bike about 3.5 weeks to fully go around. I have to have the seat high but i can pedal.
You’re lucky you can do the bike without pain! I had bilateral TKR on 7/6/20. I started doing the recumbent stepper as a 5 minute warm up at PT in week 2. I loved it; it loosened my knees up so nicely. Last week my therapist put me on the stationary bike for an 8 minute warmup. My range of motion was ready for it, but it was so hard! My quads hurt; the back of my right knee hurt. The next two days I was so sore I could barely walk. I rode it again for 5 minutes on Monday with the same result only I was slightly less sore on Tuesday. Maybe I just need to get used to it.
So I am doing well but have a question regarding ROM. My knee hurts when i bend on the backside. Is that normal? It doesn’t feel swollen but thats where the pain is when I bend. I think the tendons are just super tight?
I have been having some major issues with back of knee pain in my right knee since surgery. The left is totally fine. Sometimes it’s so bad that the pain radiates down to my calf, around to my shin, and down to my foot. Then all the muscles in the lower leg get knotted up. It is starting to hamper my recovery, and my right knee is falling behind my left. During week 1, I went on muscle relaxers for it. Riding the exercise bike on Monday really aggravated it. I was able to show my therapist exactly what was happening, and he immediately massaged out the knots. I asked which tendons were causing the problem. He said it is my hamstring. It is super tight, so he gave me some exercises/stretches to help. Try walking backwards - toe, then heel, and focus on the heel stretch when you do it.
As soon as I finish my 30 days on blood thinners (Xarelto), I’ll be able to take Advil, which should really help with the hamstring issue.
