    This was a difficult conversation for me since it involved redoing a previous surgery done by a different surgeon. One of my goals was to understand what would be involved in choosing to go ahead with a second hip replacement. Dr. McKinstry was very thorough in describing what to expect and in helping me decide on the timing for the procedure.

    Top notch, understanding, helpful
