I contacted Dr. Keller and Dr. Lindholm for a 2nd opinion as I knew of their excellent reputation from a past experience with them. I saw Dr. Lindholm immediately and he was and continues to be terrific. He took the time to explain what was going on in reviewing the x-rays then did the same after he ordered a CT scan. He diagnosed a fractured tibia below the knee replacement which was missed by the first Orthopedist. I am already feeling better after a week of non-weight bearing on the leg.
