Knee replacdment coming 4/4/19

I was hoping with all my healthy lifestyle improvements to escape the knife! Last summer/ fall my knee was great then cold winter came and Boom. Ive been going for therapy and the physical therapist said I needed to see orthopedic surgeon, so I did. He explained that with my " knee deformity" so severe( knocked knee or valgus), my bones are not only rubbing against each other but its causing my femur to turn, which is affecting my hip. Surgery is the only fix. The good part was he was impressed with my wt loss, strength in my legs, etc so my hard work should help my recovery. Im a big chicken so will try not to stress my self out waiting for the event. My goal while I wait is to keep doing my exercises and drop a few more pounds.
