Our fellowship-trained joint replacement surgeons perform a high volume of procedures each year, helping patients reduce pain, restore mobility, and return to active lifestyles.


What Is Joint Replacement?

Joint replacement surgery is used to relieve pain and restore function when arthritis, injury, or joint degeneration limits mobility. During the procedure, damaged cartilage and bone are replaced with advanced implants designed to improve movement and reduce discomfort.

Joint replacement may be recommended when:

  • Joint pain limits daily activities
  • Non-surgical treatments no longer help
  • Arthritis causes stiffness or swelling
  • Walking or standing becomes difficult
  • Sleep is disrupted due to joint pain

    Very Manageable and Comfortable

    I recently ran the Tokyo Marathon and although I have the typical physical issues that go along with a race, the major concerns with my knees had absolutely no impact or posed any challenge to the race. I had no pain at all in my knees, not even the more severe left knee. My hips had minimal discomfort at best. As a Masters Distance runner, I believe our HCP’s are partners in our training and an integral part of an athlete’s success and Dr. Rubano is an excellent example of that partner. For this last race in Japan, he helped make a very challenging course very manageable and comfortable. So thank you!

    INSPIRATIONAL, INNOVATIVE SURGEON

    Dr. Steve Dellose is a most inspirational, innovative surgeon. He is always confident, comforting and compassionate with a smile. He took that extra moment to share additional insight or calm my anxieties as I approached the next stage of the healing process. I was fortunate and honored to be included in some of his latest creative techniques. In the early stages of my total knee replacement he detailed how I could guarantee my own success with a positive attitude and a dedicated physical therapy conviction. His philosophy permeates throughout the entire office, his surgical team and even his patients. We all sang the same tune…”your rehabilitation is dependent on your own efforts”…”it is very important to get your leg straight”…”0”degrees” the “sooner the better”…..”your recovery will be so much faster”…..How could I not listen and work even harder to achieve great results…..and I did!…Thank you Steve…..you are the epitome of the word “healer”. You have given me my life back.

    Gave me my life back!

    DOS has been absolutely amazing. I can't rave about their office and specifically Dr. Nick Patel, enough. I had a knee replacement on May 14, 2024 and let me tell you. I should have let Dr. Patel replace this knee years ago had I known the recovery would go as well as it has. Not to mention the scar, or lack thereof. Really, when the pigmentation returns, you won't be able to see the scar. Anyone out there dealing with bone on bone at your knees, please, look up DOS and trust them and what they tell you. It has not been just a walk in the park. It has been extremely painful in the beginning, but there is light at the end of the tunnel. I need my other knee replaced and as soon as I recover financially from being out of work, I'm going right back to DOS. They will give you your life back!! Thank you Dr. Patel and the entire DOS staff for your support.

    Walking with no cane!

    Dr. James Rubano did my total hip replacement on September 16th and I am so pleased with my recovery. It has been 2 weeks today and I can walk (small steps) without the cane. I highly recommend Dr. Rubano and his whole team at Delaware Orthopaedic Specialists! Thank you so much.
