Stephen J Ilario M.D. | Kaiser Permanente

"I underwent hip replacement surgery on 11/3/2025 with Dr. Stephen John Ilario, and my experience has been overwhelmingly positive. The surgery was intimidating, but Dr. Ilario and his team were organized, supportive, and reassuring. From the pre-surgery consultations through recovery, every member of the team treated me with respect, kindness, and professionalism. They took the time to answer my questions and ensure I understood what to expect. The level of coordination and communication was excellent. Most touching is their ongoing commitment to my care. Even months after surgery, they continue to check in with periodic wellness calls to monitor my progress. I am extremely happy with both my surgical results and the care I received. I would confidently recommend Dr. Ilario and his team to anyone in need of hip replacement surgery."

"I had an excellent experience with this Dr. Ilario from start to finish. Communication was clear, professional, and reassuring, and I felt confident in my care throughout the entire process. My recovery has exceeded expectations. By about three weeks post-op I was pain-free, walking without a limp, and already back at the gym doing the rowing machine, stationary bike, and light squats. The improvement in my mobility and quality of life has been remarkable. I would highly recommend this surgeon to anyone considering hip replacement, especially those who want to return to an active lifestyle."

"I recently underwent a left knee partial arthroplasty unicompartmental performed by Dr. Stephen J Ilario and I could not be more grateful for his expertise and care. From the very beginning, he carefully reviewed my MRI and X-rays to ensure I was the right candidate for partial surgery. His attention to detail and commitment to choosing the best treatment gave me great confidence. The surgery itself was performed with exceptional skill, and my recovery over the past two and a half months has been smooth and encouraging. Dr. Stephen J Ilario not only did an amazing job surgically, but also provided clear guidance and reassurance throughout the process. I truly appreciate his professionalism, precision, and compassion. I would highly recommend Dr. Stephen J Ilario to anyone seeking orthopedic care--he is outstanding in his field."

"Game changer! As an RN who has worked over 40 years in a multitude of inpatient and outpatient settings, including prepping/clearing patients for a total joint replacement, I am fortunate to have had Dr. Stephen J. Ilario as my total knee replacement surgeon. Not only did he take the time to truly listen to my concerns and answer all my questions, but his expertise in the OR was literally life-changing: precision, skill, and a whole lot of magic. The surgery was a total success, and I'm already seeing amazing results. My incision looked straight as an arrow. I owe it all to Dr. Ilario's attention to detail and personalized care - he made me feel like I was his only patient! His strong analytical skills and expertise are undeniable. If you're looking for a surgeon who truly cares and gets results, look no further! Dr. Stephen J. Ilario is the real deal!"

"Dr. Ilario performed my complex knee replacement in 2014 and did an absolutely beautiful job. The results have been excellent, and I've had lasting comfort and mobility ever since. Because of that experience, I've chosen him again for my upcoming hip replacement. He's extremely skilled, professional, and also wonderfully congenial -- he truly cares about his patients and takes the time to explain everything clearly. I have complete trust in his expertise and highly recommend him to anyone considering joint replacement surgery."

"Dr. Ilario is an amazing surgeon. He is very precise, professional and he cares. The genius in him is obvious. He's not much for chitchat and focuses directly on the orthopedic problem. I had a hip replacement by Dr. Ilario and I was up and walking without pain or pain pills the very next day! After surgery, he said to contact him directly if I had any concerns or questions. I felt in good hands. Thank you Dr. Ilario."

"Dr. Ilario and I discussed my recent full knee replacement surgery. As usual, he explained in good detail all I need to know about the path forward with my new knee. He also emphasized the importance of my physical therapy regime. He is a fine doctor, and I am truly grateful to be under his care."

"All I can comment on is the end result of hip replacement surgery. I am able to perform daily tasks and movement with very little pain anymore. I attribute this to Dr. Ilario's excellent surgical skills."
