Hi Betty, Thanks for replying to my post. This is my main concern is the knock knees. Can I ask what you had done first? If it was a hip did you need the knee to be done very shortly after the hip? If I didn't have my daughters wedding this year I wouldn't be so hesitant. Did I wait too long? Probably? I didn't have pain in my knees but I did have the deformity from the knock knees. I exercised regularly and it kept my legs strong. Every surgeon I saw said "I don't think you're ready because the pain isn't keeping you up at night and you're not begging for the surgery ASAP". Now the hip is doing me in before the knees are. Just would like to hear what you decided to do first. Thank you!
