Thank you for that information. I can see that Dr. Conte specializes in arthroscopic procedures and is not a hip or knee replacement surgeon. Before you commit to this second OATS procedure, I suggest you schedule a consultation with one of the surgeons at Rothman who does do joint replacements regularly. When I checked, there are doctors in New Jersey that seem to be relatively close to you. If you would like me to help you pick someone, let me know how far you are willing to drive. For example, a good choice for you might be Dr. Joseph Bogdan in Brick Township or Dr. Michael Harrer in Marlton, NJ. I didn't go through all the physicians at Rothman for other options, but will be happy to help you locate someone to talk with. You want to be sure you are making the correct decision in having this second OATS procedure and the only way to do that is to have all the information possible about your knee.
