My apologies Cyndi. You did mention you are on the stationary bike every morning.

Two things for your consideration:

1). Use ice on your knees, but never heat. Ice reduces inflammation and pain. Heat is very soothing for muscles, but it causes a rush of blood into the knee capsule, and this rush of blood causes inflammation, swelling, and pain. So ice, ice, ice - in my opinion.

2) You didn't mention stretching. There are stretches for the quads, hamstrings, and Illiotibial Band (ITC) that may help. If the pain is on the outside of the knee, it could be a tight ITB which can be stretched.

Finally, because you are 16 mos post-TKR, have you asked your Dr about this? It may be tie for an x-ray or MRI just to make sure the prosthetics are properly seated and aligned.

I hope this helps. I'm a bit of a veteran on joint replacements (knees, hip, shoulder) so please let me know if you have questions.

I hope you find some relief Cyndi, and soon!

Joe
