It is has been 5 months since I had my partial knee replacement with the Comformis IUni. I am totally happy with the results. The surgery went just like Dr. Mack and his staff explained and my recovery has gone along much faster and smoother than I had ever anticipated. When I refer my friends to Dr. Mack I tell them he is just like meeting your next door neighbor. Dr. Mack and his staff are extremely professional but yet very caring.
