Bowie, MD |
This was a smooth surgery with no complications. I was referred to him through my orthopedic doctor. I am so glad to have scheduled an appointment with him. Although its an hour away, I did not mind taking the drive for such an excellent doctor.
in Parkville, MD |
I received wonderful care and a terrific outcome after having total hip surgery. Dr. Delanois is an experienced, caring surgeon and I felt total confidence from beginning to end.
in Towson, MD |
I had a hip replacement 9-1/2 years ago with Dr. Delanois with excellent results, up until now. Unfortunately, there was hardware failure (not his fault) and we had to have revision surgery. I was as happy this time around as I was the first time. Dr. Delanois and his team put you at ease, explain everything well, take their time at all steps along the way. I will likely see him for the next part of me that wears out...the other hip, knees or shoulders...
Glen Burnie, MD |
Dr. Delanois is a partner with you from beginning to end. He takes the time to listen to your questions and concerns and makes sure you have a clear understanding of the answers. He has a fantastic bedside manner and makes you feel comfortable.
in Randallstown, MD |
Dr. Delanois repaired a torn rotator cuff on me twice. He made me feel very comfortable and put to rest any anxiety I had about the procedure. I highly recommend this doctor and his team. I had a very successful recovery experience which was unlike that of others that I talked to that had this type of surgery. I attribute my successful recovery and experience to Dr. Delanois. He is the best!

Reisterstown, MD |
He did hip replacement two weeks ago and so far I am very happy with the results. He is easy to work with and talk to.

When Dr. D. and I met, I was addicted to Opioids. He told me sternly that I would not be a candidate for knee surgery being addicted. He told me to get off anyway I knew how. I eventually did. I got all of the tests required before surgery. The surgery went very well. He has an excellent team. My Post-Op appointment required removing stitches. He removed them and we talked about my prognosis. I am recuperating well.
in Lutherville Timonium, MD |
One of my worst experiences ever with a doctor. The entire appt was less than 3 mins. He actually said he was in a hurry and had to move on. No explanation, no discussion, nothing. They are literally running a surgery factory. I can't think of a time when I was treated so poorly. And the poor R.A., the doc treated him like he didn't exist. The office and staff were wonderful. The doctor should be ashamed of himself. I will seek a doctor who actually cares.

Dr. Delanois and his team are caring & concerned about the health of their patients. Dr. Delenois is extremely competent and professional. He was so easy to reach. Especially through the Health loop. Which is a very good Preop and post op communication program. I was happy to find that Dr. Delenois responded to any concerns so quickly and completely. No matter what time of day or night. It was truly comforting to know that whenever his name was mentioned all the responses were were positive
in Towson, MD |
I am just back home after hip replacement surgery with Dr. Delanois. I left the hospital in much better shape than I was when I went in. I had so much pain prior to surgery. And that is all gone. Just post op pain that can be managed. Always nice to see Dr. Delanois come walking in--he's his own little ray of sunshine.
Middletown, MD |
Dr. Delanois is extremely competent and professional, but he is a genuine person you can talk to. He answers all questions willingly and gives complete technical answers. I felt very comfortable choosing him as my surgeon, and I have had a spectacular outcome.
in Elkton, MD |
Dr, Delanois and his staff are very caring people that truly are concerned about the health of their patients. Easy to reach them to express any concerns you might have, and no problem for them to help you, even if it is just a matter of education. They don't just complete an operation and then forget who you are; they truly care. Although surgery is not an easy option to decide on, sometimes it is the best decision for us. They will walk you through the process, & answer all your questions.

I had a partial knee replacement less than two weeks ago and I am alreadywalking without a cane and have regained all of my flexibility. Most Iimportantlt, my knee feels better than it has in over two years, since I injured it. If you need joint replacement, go see Dr. Delanois!
