opinions needed

Weird question: My knee replacement is on hold as my hubby needs an unexpected surgery and he will be my caregiver. So, I have too much time to think about the surgery I dont want to have, lol. My knee is in better shape now than it was a yr ago as Ive worked hard riding my exercise bike etc. My pain some days is non existent, other days it reminds me it's there. Surgeon says my valgus( knocked ) knee is bone on bone, valgus is causing my femur to twist causing my hip to turn in, etc etc. I dont doubt that as I can tell my valgus is worse. I guess my two questions are 1. Why are my symptoms better when xrays show worse 2. If I back out of the surgery, will I be doing damage to myself due to valgus?

I am going to get a second opinion next week but wondering if anyone else has had similar situation?

Addendum 3/5: saw ortho doc for second opinion.

I love it when docs tell me what I want to hear!!! He said cancel surgery, you only want knee replacement when you have exhausted everyother option. Continue on with your wt loss, exercise, strengthen your core. Only consider surgery when the pain is bad and daily, you will know. He said it might b 6 mo, 2 yr, 5 yr, never. I was sooo happy when I left and more motivated to be more aggressive with diet/ exercise.
