I have had 4 surgeries, and multiple injections into my knee because of residual damage from having had a badly broken leg. Dr. Ong did my last, and final repair. I am now 6 months past my total knee replacement; and I haven't felt this good in 20+ years! For the two years prior to this surgery I was either wearing a leg brace from hip to toe, or walking with a cane... or both, and I was afraid that it would get no better than that. Within 3 months of my surgery I was able to walk 3 miles without a cane. At 6 months I am able to walk 5 miles 3 or 4 times a week (at age 68); and I am down 25 pounds! Do I still have some pain....yes, of course! But it gets better with exercise now, instead of worse! And the scar has healed beautifully, as well. I'm actually able to crawl on my knees to play with my dog, with minimal pain. He did a great job on this knee replacement.When coming into his office for pre and post op visits I was always greeted nicely, and the wait was never more than a few minutes. During this pandemic the staff did a good job of keeping traffic in the waiting area to a minimum. The back office staff is friendly and professional, and very efficient at keeping things moving along.... even with a chatterbox like myself talking their ears off.I highly recommend Dr. Ong's office and skills for whatever your orthopedic needs are. I had a 35 year paramedic career.... so I think I have a pretty good ability to assess the difference between a "good" doctor, and a "great" doctor. Dr. Ong is one of the truly talented, "great" ones!Thanks for helping me get my active life back again, Dr. Ong!
