I am also located in Cincinnati. The best knee Doctor in the area for arthritis/cartilage problems (in my opinion) is Dr. Noyes for Cincinnati sports medicine. I had a single cartilage defect on my patella. He was very knowledgeable and told me to wait as long as possible for surgery. However just like you, I wanted to take the risk and have a surgery that would help me get my active lifestyle back.
Ultimately, after much research I ended up having the cartiform surgery in Indianapolis with Dr. Farr. Dr. Noyes had no specific training with cartiform. He only offered Denovo which seems to be much more hit or miss based on the testimonies. I have yet to hear a negative story about cartiform. The good thing about cartiform is it is usually covered by insurance while Dr. Broyles procedure is not. Unfortunately it sounds like you have several lesions, so cartiform might be ruled out. If cartiform is not ruled out for you, then I highly recommend it as I can already run and squat pain free at 9 months post op
