Dr. Hummel first did arthroscopic meniscus repair on each of my knees. A couple of years later, due to severe arthritis, I had to get total knee replacements done. I would not have gone to any other ortho doctor for the TKR, even though I did seek a second opinion because I was hoping I wouldn't need knee replacements yet. The second Dr said the same thing, so I scheduled theTKR with Dr. Hummel. He did the right knee at the end of October. I did the therapy and exercises, and regained full range of motion by my 9 week checkup. The left knee was done at the end of February, with similar, excellent results. Dr. Hummel is very specific about what he wants you to do to heal. But if you follow his instructions, you get the best results. I don't hesitate to recommend him highly. read more
