It's been a long time since I updated. It is now 7-1/2 months for my left knee and 6 months for my right. I've been having a lot of trouble with muscle soreness and arthritis in other joints. My knees, though, are doing well. I can do whatever I want or need to do, except still cannot kneel because it hurts. I do have multiple sclerosis, though, and think that is the cause for a lot of the muscle soreness. I have been waking several times at night with pain in my calves and thighs. I did some research and started taking calcium, magnesium, and vitamin D. At the same time I started krill oil. I also got something called celedrin - an antiinflammatory fatty acid. It's only been a couple of days, but already I have no more pain at night and stiffness has improved. I hope the improvement continues.
As far as my knees go, the left is good. Still with a bit of soreness on certain movements. The right is still giving me a problem with an occasional jab of pain at the medial patella. The problem with sciatica type pain on the right has gradually improved and only bothers me occasionally.
I can sleep as long as I want on either side, go up and down steps, get up out of a low chair, etc. My thigh muscles still feel somewhat weak when climbing steps. Pain level is 0, except for occasional soreness on movements or the jab I get occasionally on the right knee. I can walk as long as I want as far as my knees go, but my back starts hurting after a while.
All in all, I am satisfied with my new knees. Hopefully the muscle soreness (all over) and the other joints will continue to show improvement.
