Real Stories, Life-Changing Results

Dr. Antoniou was great. I have Paget's in my left hip and femur. Dr Antoniou had operated on people with this problem. He had to so some straightening out for my femur and it worked well. Had to wait for less then a week to have the operation. Would have had to wait at least another year to go through our health system. Was in a situation where I could hardly walk as I had bone on bone. Health care system did not care. Told me to just wait. Can now do fun things with my grandkids.

I cannot express enough gratitude for the exceptional care I received from Dr. John Antoniou and the entire team at Westmount Square Surgical Center. From my very first consultation to my post surgery recovery, every step of the process was handled with professionalism, kindness and expertise. Dr. Antoniou took the time to explain everything in detail, ensuring I felt confident and informed about my hip replacement surgery. Their skill and precision made all the difference in my recovery.

Dr. John Antoniou is an exceptional surgeon. My experience with having my hip replaced through the Westmount Ortho Clinic was amazing. He, and his team, took the time to thoroughly answer all of my questions to properly prepare me for the surgery. I travelled from Calgary to Montreal because I wanted the best surgeon. I highly recommend Dr. Antoniou to all choosing to have a hip replacement operation.
