Listening and clear explanations reviews.

I was referred to Dr. Prem Ramkumar after a sports injury that left me needing ACL and meniscus surgery on both knees, and I honestly couldn’t be more grateful that I was sent his way. From my very first appointment, Dr. Prem and his entire team made me feel like I was in the best hands. I had never been through an injury or recovery like this before, and the thought of having surgery on both knees was overwhelming. Dr. Prem walked me through everything step by step, answered every question I had, and always made sure I understood what to expect. He gave me so much confidence going into both surgeries and throughout my recovery. From pre-op, to surgery, to all of my follow-up appointments, I have felt genuinely cared for and supported. Dr. Prem is not only an incredible surgeon, but someone who truly cares about his patients and their recovery. His entire office has been wonderful as well, and that kind of support makes such a difference when you’re going through something this challenging. I still have more recovery ahead of me, but I’m so thankful for how far I’ve come and for the care I’ve received along the way. I’m incredibly grateful to Dr. Prem and his entire team and would recommend him without hesitation to anyone dealing with a sports injury or needing orthopedic surgery.

Writing this review 4 week post op from a meniscus repair surgery. I seriously could not recommend Dr Prem Ramkumar more. I had been dealing with a horrid aching pain in the back of my knee for a whole year. I am 26 years old and it had negatively affected me so much that I could no longer do most physical activity that I liked to partake in. I had even gone to see multiple doctors/orthos who gave me indefinite answers. But - it wasn't until I met with Dr. Ramkumar that we were able to finally figure it out. He took one look at my MRI images and instantly knew what it was. Six weeks later from that appointment and my life is forever changed for the better. If you have knee or hip pain, don't wait!! See this doctor, it will be the best decision you could ever make!

Dr Ramakumar and his staff were so accommodating. Everything was explained, everything was painless and the results of my knee replacement were great. You can't go wrong choosing Dr. Ramakumar. Bob Robilotta

As a Div 1 Track athlete with bilateral hip pain before meeting Dr. Ramkumar no one I went to could accurately tell me what was going with my hips. After the first visit with Dr. Ramkumar he explained in detail what was going on and what my options were, from there I decided that I wanted to go through with getting a bilateral hip arthroscopy. He explained exactly what was going to happen during the procedure and about the recovery process before hand so there were no surprises. The procedure went great and I would say the recovery went even better. There was minimal to no pain within the first few days and I was walking the day of the procedure. It has now been around 4 months since the surgery and with the help of physical therapy and strength training my hips feel way better than they did before and I am able to run pain free again. I am very grateful to Dr. Ramkumar for playing a major role in my journey of getting back on the Track.

For almost half of my life, pain was not something that happened to me. It was the backdrop against which everything else happened. I am 23. Since I was 13, I cannot remember waking up without stiffness/pain in my back. Pain has a way of changing shape over time, beginning as a symptom but becoming part of your identity. Somewhere along the way, I stopped hoping to feel better and accepted it as part of my life. As a former UCLA Division I tennis player who has always loved being active, I spent years searching for an answer: physical therapy, massage, cupping, acupuncture, strengthening, injections, imaging, and countless evaluations across the world. I never got a clear diagnosis despite seeing several orthopedists, and was told to consider chronic pain syndrome, with exploratory spine surgery as a last resort. Every opinion carried the same message: learn to live with it. Meeting Dr. Prem Ramkumar was the first time someone wasn't just listening to my symptoms; he was trying to understand my story, asking why instead of accepting the limits of what had already been tried. As a former D1 athlete, I'd worked with plenty of physicians, but he treated me with the same precision I've learned he gives medal-winning Olympians and Stanley Cup champions he treats professionally. I felt like one of his VIPs. It changed everything when he diagnosed me with hip impingement after a careful battery of tests, since my presentation was atypical. It was the first time I had an answer, and a solution. What will stay with me forever is not just the surgery itself, but the morning after. I sat on my bed and waited for the familiar stiffness in my lower back. It never came, and to this day, it still hasn't. I biked 130 miles the first day after surgery!! I began physical therapy on day three at his office, and weaned off my crutches and brace within a week. Since then, I have moved through daily life without pain. The absence of pain has been remarkable, but what surprised me even more is everything that was restored: I sleep through the night, my mind feels quieter, and the constant background noise chronic pain creates has disappeared. My mood and energy are better, and I'm standing taller. My wearable's resting heart rate and sleep scores reflect it too: my body is finally healing, not merely enduring. It isn't just excitement, but disbelief; my brain keeps searching for the pain it's so accustomed to finding. Then, little by little, I realized it isn't temporary relief. It's freedom, for the first time in a decade. People often think surgery changes your body. With Dr. Ramkumar, it also changed my relationship with the future. For years, every decision carried an invisible calculation: could my back handle this, would I wake up unable to move? Pain quietly dictated where I went and who I believed I could become. I didn't realize how much space it occupied until it was gone. Today, I believe this surgery will make me a better athlete than I was. So many others told me this wasn't possible. Dr. Ramkumar never accepted that answer. That speaks to his character: his persistence, his curiosity, his genuine commitment to patients who've spent years searching for someone willing to keep looking. He treated me as a person whose story deserved to be understood, not another MRI. As someone who now works in medicine, I've learned he believed in me when no one else would. Medicine is often described as restoring function. Sometimes it restores possibility. No review could fully express what he gave me: mornings I had forgotten were possible, confidence in my body, and a future no longer defined by limitations. If you have spent years searching for answers, feeling unheard, or wondering whether anyone will look beyond the obvious, I cannot recommend Dr. Ramkumar enough. My experience changed the course of my life, and I will always be grateful he refused to stop asking why, and fixed me. Additionally, Margo, his NP, matches that same excellence. Her clinical sharpness was matched only by the genuine care she brought to my recovery.

Dr. Prem Ramkumar is amazing. I recently had my second total knee replacement from him. He is kind, considerate, knowledgeable, current with the latest technologies, all around, the ideal doctor for a joint replacement. Less than one week after surgery I feel the progress I’ve made. My physical therapist was impressed that i could slide my knee into almost 90 degrees 4 days post op. I’ve never experienced a more caring and responsive doctor. He responds to emails very quickly and answers all questions. He understands his patients and is never dismissive. Unrelated to my knee replacements that Dr. Ramkumar completed, I mentioned hip pain I am experiencing. Not only did he refer me to a colleague he respects but he phoned the colleague to discuss my situation. He asked to be kept in the loop to see me through my hip issue. I am so impressed with his kind and compassionate demeanor. I was impressed with Dr. Ramkumar after I first met him, but even more so impressed after I looked at how many studies he performed, research he completed, and papers he published. In speaking to so many about him, the overwhelming consensus seems to be the same, Dr. Prem Ramkumar is top in his field and a lifelong learner.

I first learned about Dr. Ramkumar because of his reputation for taking care of elite athletes, including Freddie Andersen, one of my favorite NHL players. As someone who has always been very active and views sports and movement as a major part of my life, I was immediately interested in his approach. My experience with Dr. Ramkumar showed me why he has earned a reputation among athletes. He has an exceptional ability to understand the demands that active people put on their bodies and combines that perspective with deep orthopaedic expertise. He was incredibly thorough, thoughtful, and took the time to explain things in a way that made complex issues easy to understand. What stood out to me most was his commitment to helping people maintain an active lifestyle. He doesn’t just look at an injury or condition in isolation — he thinks about the person, their goals, and what they want to get back to doing. That mindset is especially valuable for athletes who want to continue performing, competing, and doing the activities they love. Following his guidance, I have felt a renewed confidence in my ability to stay active and continue pursuing the things that are important to me. He helped me better understand my body and gave me the perspective and confidence to keep pushing myself and do things I wasn’t sure I would be able to do again. Dr. Ramkumar is the type of orthopaedic surgeon athletes should seek out — someone who understands that getting healthy is not just about reducing pain, but about getting back to the activities, goals, and performance levels that matter most. I have tremendous respect for his knowledge, his approach, and the care he puts into helping active people get back to doing what they love.

I was taken by LB Fire to Memorial after falling backward off my paver-covered porch and walkway, sustaining 4 fractures to my femur and making my 2012 hip replacement unstable. I was seen by the orth trauma team and referred to Dr. Ramkumar. He came to my room in the hospital, explained what was on the xray and CT scan. We planned for surgery after July 4th holiday. He went over potential benefits, complications, plan of care, etc. I was acutely aware that not too many ortho could do the complex repair. I had surgery, stayed 3 nights. Pain managed. Excellent care from all hospital staff, dept. My first post op appt with Dr. Ramkumar was positive, with wound vac and staple removal. Fracture healing was 2.5 weeks ahead of schedule! PT to be started in the next week at his office. I have to say when I called the office on a Monday morning at 8:01 a.m. to report wound vac battery died, I had a response within 1 minute. I found out that Dr. Ramkumar responded to me, issue resolved. I have positive outlook for my future, as a result.

Dr. Prem Ramkumar performed FAI hip arthroscopy on me, and I can’t recommend him highly enough. I come from a combat sports background - Muay Thai, BJJ, grappling, and powerlifting - and years of that caught up with my hips. What I want people to know is that this surgery exists. A lot of athletes get told hip pain is just wear and tear, something to live with or manage until a replacement down the line. That’s not the only option. Hip arthroscopy for FAI is a real, minimally invasive procedure, and finding a surgeon who specializes in it makes all the difference. Dr. Ramkumar explained exactly what was happening in my joint, was realistic about recovery timelines, and clearly understood the demands athletes place on their bodies. I’m scheduled to have the other side done with him - which says everything. If you have hip pain that won’t resolve, get it looked at properly instead of delaying.

I am 66 years old and played and enjoyed competitive sports my entire life up until 3-4 years ago. My left knee pain was consistently keeping me from enjoying things that contributed to my overall happiness and wellbeing. My wife and I could not longer bicycle or walk together as we always did due to my knee pain. My primary care physician referred me for X-ray and MRI, which resulted in me promptly being diagnosed with severe osteoarthritis of the left knee. I was then referred to Dr. Ramkumar and his team for physical therapy and evaluation. While the physical therapy did not resolve my arthritis, it was a great step in the right direction and I am very thankful to have met Dr. Ramkumar and his entire team. After 10 physical therapy sessions, I decided to proceed with total knee replacement after re-viewing imaging and treatment plans again. Within 10 minutes, he explained that my meniscus was completely torn and the cartilage in my knee was eroded and non-existent! He recommended a total knee replacement and explained in detail the preparation, surgery itself, recovery, and answered any and all questions I had. I was scheduled for surgery and was emailed information including emails of the process. I participated in an online zoom call with a registered nurse, who further explained my surgery and peri-operative recovery extensively. I was very informed about the things i would need like ice packs, medications, and more! My surgery was on 5/26/26 and I was walking the same afternoon and went home the same day which is a blessing. The first night I had difficulty sleeping as I had reluctance taking the prescribed pain medications, but after taking pain mediations the next day, my pain was managed and I slept perfectly. After the second night, I no longer needed any narcotic pain relief. I also began at home physical therapy on day 2 and I worked diligently to get my life back. Working hard paid off big time! After my 2 post-op surgery appointments with Dr. Ramkumar, I was cleared to drive and resume normal activities. It has been less than 2 months since surgery and now I can walk miles at a time, bicycle miles at a time, and swim as long as I desire. Thank you so much to Dr. Ramkumar and his team, everyone of them works cohesively together and answers any and all of my questions and concerns. They helped to make my surgery and recovery seamless and successful. While I hope to never need no additional surgery, Dr. Ramkumar will be my first call if I ever begin having trouble in my right knee and I have no hesitations that he is the perfect man for the job! I have already referred him to my personal friends and would not hesitate to continue referring him to anyone I know. I am back to all activities and excited to have my life back with no pain, as all my expectations from before surgery were exceeded. - R. Stuver.

Went in for an acl sprain and meniscus tear, Dr. Ramkumar explained things clearly and easily while reassuring my surgery would be safe. This was my first surgery and Dr. Ramkumar was kind and inspirational in my recovery after surgery.

I had maniscus repair done by Dr. Ramkumar. Everything went perfect, minimal to no pain back to being active. He and his staff were professional at all times, they listened to my issues and addresses them. I have recommended Dr. Ramkumar and will continue to recommend him.

I owe a lot to Dr. Ramkumar! I had serious arthritis in my hip and was in constant pain. I did not want to give up the activities that I enjoyed, but one by one, I was doing less of them because of that pain. Dr. Ramkumar explained the whole process of hip replacement thoroughly and I made the decision to do it. This was one of the best decisions I ever made. Through information on Dr. Ramkumar’s website, a brochure provided by his staff, and a zoom class every step was explained. When I woke up from surgery the pain in my hip gone. Sure there was surgery pain as expected but that horrible hip pain was completely gone. I can’t say enough about how supportive Dr. Ramkumar, his staff, and the physical therapy clinic on site have been. I now walk everyday, do yoga, water aerobics, and just completed a three hour walking tour that I had purchased but had been unable to do as it was too painful. I feel I have been given an incredible opportunity. Thank you Dr. Ramkumar!

Shockwave therapy was a game changer for my achilles tendonitis! After dealing with persistent pain that just wouldn't improve, this treatment made a massive difference in my recovery, mobility, and overall pain levels. A huge shoutout to Nurse Practitioner Margot for being so amazing. I was a little nervous for my first session, but she took her time to explain the process and reassured me it wouldn't hurt, which put me completely at ease. Highly recommend this treatment to anyone dealing with stubborn injuries!

I cannot say enough positive things about Dr. Ramkumar and Margo. Dr Ramkumar performed two knee surgeries for my mom, and both were highly successful. From the very beginning, he demonstrated exceptional skill, professionalism, and genuine compassion. What stood out most was his outstanding bedside manner. My mom being a patient with Parkinson’s disease, I greatly appreciated his patience and understanding. He always took the time to explain the surgery, and recovery process in a way that was easy to understand. He never made her feel rushed and was always willing to answer questions and address concerns. Margo was also very patient with my mom and took the time to give her pep talks and encouragement when she was feeling defeated during the recovery process and expecting to be recovering faster. Thanks to Dr Ramkumar’s expertise and care, my mom’s surgeries and recoveries went smoothly. I am extremely grateful for the excellent care from Dr Ramkumar and Margo and would highly recommend to anyone seeking an orthopedic surgeon who is both highly skilled and truly cares about his patients.

Dr. Ramkumar helped me during one of the most vulnerable and uncertain times of my life. As a 20-year-old college soccer player, tearing my ACL and meniscus and needing reconstruction with a patellar tendon graft right before my season was devastating. From my first appointment, I knew he was the right surgeon for me because of his dedication to sports medicine, his expertise, and the genuine care he showed throughout the process. He took the time to answer my questions, explain my options, and give me confidence when I was scared about the future. Today, I am 4 months post-op and proud to say that I am jogging again. It’s been an incredible blessing to have my surgery performed by Dr. Ramkumar. The entire team at Commons Clinic has been outstanding. Everyone is professional, kind, and encouraging. I also attend physical therapy right in the clinic, and the experience has been excellent. From the front desk staff to the physical therapists, including Mina, everyone has played a role in my recovery. I am determined to come back stronger than before, and I’m grateful I made the decision to trust Dr. Ramkumar and his team. This surgery has given me a second chance to live an active lifestyle—to run, cut, jump, compete, and do the things I love. That’s something I’ll never take for granted. Thank you, Dr. Ramkumar and the entire Commons Clinic team, for helping me get my life back.

I had hip arthroscopy surgery with Dr. Ramkumar at Long Beach Lakewood Orthopedic Institute, and I could not be happier with my experience. Going into surgery, I was honestly a little timid and unsure of how good or bad the whole process could be, but everything went very smoothly and my healing has been going really well. Dr. Ramkumar, his nurse practitioner, and the entire staff were amazing throughout the process. They were thorough, supportive, and always took the time to answer questions and make me feel comfortable. You can genuinely tell they care about their patients and the outcomes they achieve. I also really appreciated having physical therapy onsite because it made recovery much easier and convenient. The whole team made me feel supported every step of the way. If you are dealing with hip or knee issues and want a doctor and team that truly care, I highly recommend Dr. Ramkumar and Long Beach Lakewood Orthopedicd Institute.

After my daughter injured her knee, we spent months being told she just needed rest, but she never fully healed. Once an MRI was finally ordered, we met with a local orthopedic surgeon, but the experience felt rushed and lacked compassion. That’s when I started researching other options and came across Dr. Ramkumar. From our very first appointment, we knew we had made the right decision. Dr. Ramkumar was kind, patient, informative, and never once made us feel rushed or pressured into surgery. He took the time to thoroughly explain her ACL and meniscus surgery along with the recovery process, which gave us so much reassurance during a stressful time. Her recovery has honestly exceeded anything we expected. She was off crutches at 2 weeks, out of her brace at 4 weeks, and now 4 months post-op she continues to do incredibly well with minimal to no pain. His physical therapy team has also been amazing supportive, patient, and truly invested in her recovery. We gladly make the almost 3-hour commutes because Dr. Ramkumar and his entire team have been the perfect fit for my daughter. We are beyond grateful for the care, encouragement, and support they have given her throughout this journey.

Prem N. Ramkumar, MD, MBA

I highly recommend Dr. Ramkumar as my husband had an excellent experience. The level of professionalism, knowledge, and personal attention was outstanding. Dr. Ramkumar took the time to listen carefully explain everything clearly and made us feel comfortable and confident throughout the process. The staff was also kind, efficient, and caring. It is rare to find a doctor who combines such expertise with genuine compassion. We are very grateful for the excellent care received. We would highly recommend this practice to anyone needing expert orthopedic knee care.

I was “bone on bone“ in both of my knees and had been to see 3 different knee specialists over the past 10 yrs. Dr. Ramkumar was the first and only one of the three to tell me that a partial knee replacement was even an option. It was what he recommended, and he backed it up with my x-rays and a clear explanation as to why a partial vs. a full was the clear way to go. Besides his phenomenal surgical expertise, one of the things I really appreciated about Dr. R is that he “got me“. I’m on the chronologically gifted side of things (71YO), but he took the time to understand how active a lifestyle I led, and the things I wanted to be able to keep doing after surgery, i.e. motocross ride, snow ski, pickleball, golf, hike and last but not least - play with our 7 grandkids! I worked out for 2 1/2 months prior to surgery to get my legs in the best possible shape and to help with recovery. Post surgery results have FAR exceeded my expectations. I know every patient will be different, but I have not experienced the pain level I anticipated. As of this writing, I’m 2 1/2 weeks post surgery and have only had to take two pain pills, and I walked 3.1 miles the day after surgery. We went to Disneyland with some friends a week and a day after surgery and walked from 9am-10:30pm. I was tired at the end but no knee pain following either walk! I would highly encourage anyone to pay Dr. R a visit, especially if you’ve already been told you need a full knee replacement. That’s nothing to mess with, and a second opinion could be very helpful in making an informed and wise decision.

I'm 3-months post-op from my meniscus repair done by Dr. Ramkumar and I'm super happy with the outcome. As a 66-year old mountain biker, golfer and pickleball player, I really appreciate his approach focusing on repair first vs automatically shaving or removing the meniscus, since repair helps slow the onset of osteo arthritis and will help extend my athletic life. The pre-op visits with Dr. Ramkumar were great! I never felt rushed, he took time to answer all my questions and discuss options. He's friendly and easy going with a great sense of humor which helped me feel alot less nervous about the surgery and recovery process. 5 stars for Dr. Ramkumar and his team!

Prem N. Ramkumar, MD, MBA

Dr. Ramkumar helped me regain my mobility and independence. The R-hip surgery lebrun year was successfully repaired, and I had no complications, no pain, no after surgery discomfort. He was meticulous about every detail and made certain to answer all questions and concerns. His staff were amazing, polite, and efficient. I can walk without limping or pain. I am truly grateful for his professionalism, and his innovative medical procedures.

Dr. Ramkumar has been one of the best experiences I could have asked for. I had a complex lateral knee injury that many doctors before misdiagnosed. Dr. Ramkumar was extremely honest, focused, and not rushed to surgery, in fact he was able in a few months get me back to normal without surgery, when many doctors prior said that surgery was necessary. He was very honest, no sugarcoating the truth, which to me is preferred when you have to make tough decisions. He was extremely knowledgeable and was able to explain the injury in a way that I couldn’t understand and feel confident in my decision making. This quality is very important when dealing with complex injuries where most average people do not understand the healing process and what you can and can’t do. I couldn’t be more grateful for him and the team putting such care into doing everything they could to heal my knee before rushing into surgery. I was concerned because this injury was quite unique I was worried I would t be able to find the right guy, but luckily I was able to get time with Dr. Ramkumar.

I was having a difficult time walking, and surgery was my last option to try and give me quality of life. My current doctor suggested a hip replacement and referred Dr. Ramkumar, a specialist in total hip replacement. I was greeted with a smile, a handshake, and encouraging words to find the best option for my situation. He suggested the anterior total hip arthroplasty surgery assisted with MAKO, a robotic arm. His knowledge of the lastest technology and providing a detail explanation of the procedure could give a shorter time of recovery, was the best option. His meticulous guide was easy to follow from pre-op through post-op and helped me with a positive outcome. I was walking the next day, no limping, not in pain and a smooth moving hip! My appreciation to Dr. Ramkumar for being in tune to my specific symptoms and providing transparency to my specific needs.
