@janieben I see you have been visiting for a while, but this is your first post. Don't you hate it when you can't figure out what is causing a pain? I am in the midst of trying to solve a pain riddle for the umpteenth time - hoping I'm on the right track this time.

Back in 2004 or 2005, I was at my wits end having been trying one thing after another to treat my back pain with little success. One night, I went on a field trip with a group, and one of the older women took one look at me and said "When are you getting your hip replaced?" I said the trouble was my back, then tried to step up a higher than normal step and couldn't! We had just been on vacation and I could only get on and off my bike by pulling up to a step or curb so I could just step through the frame - couldn't lift my foot over the ladies' crossbar, hmm...

The next week my primary x-rayed my hips and sent off to the ortho surgeon. He walked in and told me I had the "hips of an 85 year old" (I was only 54) and asked which one we should do first. Guess what? The new hips solved the back pain & the pain in one knee. My PT said "When you limp, everything goes out of whack."

Now you have two possible causes of the right knee pain - a bad left knee and recovery from 2 broken ankles! It's really great that the ortho checked out your "old" knee and pronounced it sound. I'm guessing the surgery will help get you back on track. You may need to follow the knee PT with some gait training to get your old knee, new knee, and repaired ankles to all play nicely together.

If you have any doubt, you might want a second opinion.
