    I had total hip replacement of my left hip just over 8 weeks ago. I scheduled this surgury with Dr…read moreRana at the Tarzana Center for Orthopedic Specialists, so I was in and out in about 7 hours total. I cant recommend Dr Rana and the support staff highly enough. From the moment I walked in I was greeted and taken care of by caring professionals. The surgery went smoothly and after about 2 hours in recovery I was on my way home. Dr. Rana and his team were very efficient and thorough with timely pre-op information, as well as explainations of what to expect with the surgery and the recovery. He is both a highly skilled surgeon, and a caring human being. I have little to no pain after 8 weeks and my mobility is very good; walking, climbing stairs, traversing irregular terrain, beach sand, and working around my property. I am back to playing pickleball a few times a week without any soreness or swelling, although I will admit I am playing a bit more conservatively for a while to be sure I do no damage to his fine work! I consider this proceedure to be a total success all owing to Dr Rana's skill and professionalism.

    In 2025 I underwent total knee replacement surgery with Dr. Rana and had an outstanding experience…read more I researched many surgeons and chose him because he was the most highly recommended and he truly lived up to it. His skill, experience, and attention to detail are exceptional, and he has a cheerful, reassuring bedside manner. What impressed me most was how attentive he was after surgery, personally following up with me multiple times and genuinely caring about my recovery. The office staff and surgical team were excellent, and my surgery at Tarzana Hospital was a great experience. I am extremely grateful for the results of both surgeries and would highly recommend Dr. Rana to anyone considering knee replacement.

    Exceptional Experience & Recovery with Dr. Sumit H. Rana…read moreProcedure: Outpatient Robotic Total Knee Replacement (Subvastus Approach) I can't say enough good things about my experience with Dr. Sumit H. Rana and his team. Before going into my robotic total knee replacement, I had heard plenty of stories about how grueling and difficult knee recovery can be. While I know everyone's experience is different, my recovery has been remarkably smooth. Whether I was just incredibly fortunate or benefited from choosing the right surgeon and technique, my results exceeded my expectations. The Surgery Experience The procedure was performed as an outpatient surgery at a brand-new surgical center. From start to finish, the entire process was quick, seamless, and easy. The nursing and support staff were outstanding--friendly, attentive, and genuinely helpful in keeping me comfortable and informed. Dr. Rana's surgical precision was evident right away: the incision was extremely neat, and as it continues to heal, there is almost no visible scar left. Recovery & Outcome My post-surgery pain was minimal and lasted for only a very limited window. I had great range of motion straight out of surgery, was ditching the cane and walking on my own within a week and have been hitting recovery milestones well ahead of standard timelines ever since. Recommendation During my rehabilitation, I mentioned Dr. Rana to my physical therapy team, and they told me that they always see great outcomes and rapid progress from his patients. In hindsight, although I of course did my own research, I probably should have consulted a PT before choosing my surgeon! If you are considering a robotic knee replacement, especially via the subvastus approach, I cannot recommend Dr. Rana highly enough. He and his team gave me my mobility back faster and easier than I ever thought possible.

Ms. Torres was very professional, patient, and understanding of my needs. Furthermore, Ms. Torres provided me with exemplary service. Her work ethic is what all medical personnel should aspire to. I highly recommend Providence Center for Orthopaedic Specialists.
