I had prp and bone marrow injections into my hip one year ago. I already had 1 hip replacement and wanted to go the natural route this time. I'm 68 years old and am pleased to say I have completely recovered, without pain, and am back to cross fit. I'm so pleased with these results.

I've had pain for several years from damage to my elbow due to racquetball. Doctors tried multiple steroid injections as well PRP. Learned to play left-handed which kept me on the court. Then last year my physical therapist recommended Dr Derrington as he had successfully treated the PT. Dr Derrington performed his version of a PRP injection and after a healing period I was finally able to use my right arm again with no pain at full power, and it's been almost a year!

I went in Dec 2024 to see Dr Derrington because my hip was bothering me. I have a torn labrum on my right hip and have been getting PRP on it since 2021. All the PRPs that I got from the previous ortho MD would not eliminate my pain. I heard about Dr Derrington from two friends, both praised him for the level of quality of his PRPs (highly concentrated plasma, that helps with the healing quickly). I work from home on a desk and sitting for 8-10 hrs pert day really hurts my hip. I am also very active at the gym and with pain in the hip I cant do any lower body exercises. So I got PRP in mid Dec 2024, within 5 days I was pain free, within 10 days I was back in the gym slowly getting into lower body exercises with weights and comfortable range of motion. Now 2 months post PRP processure I cant tell the difference between the "good" and the "bad" hip, both are pain free. I am really happy with the results.

I had a PRP and Stem Cell treatment for my lower back problems in December 2024. Dr. Derrington and his staff have been very helpful in working with me to diagnose the issues and come up with a treatment plan to alleviate the pain I have been experiencing for over 2 years. Dr. Derrington developed a plan targeting the lumbar region with strategic injections at the location of pain which use my own blood and stem cells for the treatment. The day finally arrived and I was greeted by a friendly staff who drew my blood and made me feel comfortable. Dr. Derrington skillfully injected the PRP and Stem Cells in the places outlined in the treatment plan using the latest technology. The procedure was only mildly painful.
After the procedure, I was a little sore - but that faded fairly quickly. I was encouraged to keep moving and do physical therapy (which I was already doing) to strengthen my core and back muscles. I also did a lot of stretching as well.
After about 4 weeks, I could really feel changes going on my lumbar region, and I was able to sit and stand for longer periods of time than prior to the procedure. It has been 8 weeks now and there have been days where I forgot about the constant stiffness and pain in my lumbar region. In terms of activity, I am doing everything I did before the procedure with the exception of lifting heavy weights. I now use resistance bands instead.
I am amazed at the results and have been very pleased with the outcome and process thus far.
If you have back pain and do not want to do surgery, you may want to check this procedure out. There is a wealth of knowledge about PRP and Stem Cells online and I highly encourage you to learn as much as possible as it may be a very good alternative to help manage pain and get you back to enjoying your life again.

Dr. Derrington and his staff are amazing!! I went there for my wrist as I was unable to do all normal activities without pain. I had PRP treatment and noticed a significant improvement within the first couple weeks. It’s been a couple months now and I no longer wear a brace and am able to almost everything I could do before I started having issues and am excited to be able to be normal again!! Highly recommend Dr. D and his team!!!

Our daughter is in the middle of her senior year XC season, and dealing with bursitis. We came to Dr. Derrington after following PT protocol and she needed something more. We were anxious about getting a cortisone shot because of the long term side effects. Dr. Derrington and his staff were professional and friendly. He evaluated my daughter's condition and suggested nano dose cortisone. She felt great the next day and returned to running the following day. I loved that Dr. Derrington suggested supplements as an alternative to NSAIDS.

I'd been struggling with persistent swelling and a Baker's cyst on my left knee, the result of cartilage loss from 30 years of running and in more recent years, the demands of mountaineering. A cortisone shot provided only very temporary relief with immediate setbacks if I returned to running, and I wanted to avoid having a series of shots and risking further damage to my knee. My coach and gym community referred me to Dr. Derrington, and the consultation for PRP treatment left me feeling very at ease and confident that this would offer the best long-term results and allow me to continue running and climbing.
Dr. Derrington and the office staff communicated everything thoroughly so that I knew what to expect, and the treatment in January was so quick and painless. I resumed strength training within a week with restrictions and a carefully prescribed 12 week plan for returning to sport-specific training with a full range of motion. By 8 weeks, I had resumed running, and was once again squatting and deadlifting from the floor- without swelling the next day. 12 weeks after treatment, I took an 8-day mountaineering course on Mt Rainier to prepare for climbing Denali, which called for strenuous lifting, sled dragging, and squatting in and out of tents each day. I felt strong, and not once in those 8 days of intense daily activity did I have any knee pain, swelling, or reduced range of motion. It felt great to get back to 100% and really boosted my confidence for future climbs.
The biggest surprise is that even after I felt like I was back to 100%, my left knee has continued to improve, and it now feels like my stronger knee. I'm contemplating having a PRP treatment done on the other knee! It's a no-brainer when you've experienced the results and know through all the followup communication that your doctor truly cares about his patients. So grateful!

I was in dire need of a fix for my ailing back. I had 2 bulging discs for two decades and had tried everything else: pain shots, chiropractors, acupuncturists, consistent stretching, etc. But I feared going under the knife and any disc replacement. Using the cells from my own body was my next best choice and Dr Derrington was able to fix me, 100%. I have been pain free for over a year now. I work out 3-4 times a week with zero restrictions. I am thankful for Regenexx and the technology that is used by Dr Derrington and his team. I highly recommend this if you're suffering like I was for such a long time. Don't wait!

I am very picky about doctors. I researched for months, even went to a couple preliminary appointments with other prolo docs in LA; before making the trip south to Dr. Derrington. Totally worth it! I knew during the hour we spent talking that he would be my doctor. He is genuine, thorough, he listens...and skilled! The results from the actual prp procedure have been stellar. My back, hip and neck are much more stable and pain-free. I highly recommend him! Thank you!!

I was referred to Dr. Derrington by my PT therapist. I am so glad that I did! I was treated at Derrington Orthopedics for my tennis elbow. They did a great job hadling my case. Although the procedure was a bit painful and I felt an intense pressure both the doctor and his assistant remained calm and provided me with the best level of comfort and care. My tennis elbow pain is gone and I can play tennis again! Thank you Mr. Derrington and husband team!!🙏❤️👍

My Stem Cell procedure was a thorough success. I AM into my 4th month and the Dr requests a 6 month healing time frame before reassessing. It’s been a journey but each month I AM feeling more pain free. I highly recommend Dr Derrington as he is thoughtful, caring and very knowledgeable.

Derrington Orthopedics helped me get stem cells for my hip arthritis. I had very good results and a year later am doing so much better. I highly recommend this treatment and the staff and doctor here are world-class. I had excellent service and a great experience and highly recommend them!

I've been a Nurse Practitioner for over 30 years and have had regenerative medicine procedures elsewhere. Dr. Derrington is a stellar physician, diagnostician, injector, and person!!! I won't go anywhere else now. His procedures relieve pain and enhance mobility. He is a rare find, and his procedures are effective!

I have been struggling with knee pain for the past 20+ years. Diagnosis was bone on bone and osteo arthritis. Each time I went to the orthopedist I was told I was too young for surgery but they could shoot some
Cortisone in there and that should do the trick. WRONG! Cortisone just hurt and didn’t change anything. My husband heard about PRP on the radio and urged me to get a consultation…I did and I had PRP done in both knees. I hiked the Trans-Catalina trail with my daughter, something I couldn’t have done before, and am happy to say goodbye to knee pain and I only wish I knew of this procedure sooner. Life is much better with two, fully functioning, healthy knees…thank you Dr. Derrington

Dr. Derrington provided an exceptional experience. I was dealing with a knee issue, and he was able to help me get the appropriate imaging to diagnose a torn meniscus. He recommended a PRP treatment which he was able to inject under the guidance of ultrasound. I was able to rehab and am now back to running and weightlifting without limitation.
He was also able to help a family member and diagnosed a non-musculoskeletal medical condition and was able to set him up with the appropriate team to treat him.
Thank you to Dr. Derrington and his entire team!

My issue was with my neck, Dr. Derrington assessed my neck and had determined that I was a moderately pour candidate for the (PRP) platelet procedure.
It has been over 2 months and I'm happy to report I have significantly more range of motion and better mobility in my neck.
Thank you Dr. Derrington

Before I had my procedure done I was having extreme difficulty walking up stairs, putting on shoes and getting into a car. I now am able to walk stairs comfortably, get on my shoes and get into a car. I would recommend this procedure to anyone. The office is professional and I love the alternative instead of surgery. I have told everyone about Dr Derrington

I’ve been blacksmithing for 55 years with both shoulders were gone. It was bone on bone along with rotator cuffs tears. I’ve seen many doctors and all wanted to do surgery and replace both shoulders. Thank god I found Dr. Derrington. He did an amazing treatment other stem cell transplant along with PRP. I’m now able to move my arms and shoulders and I’m able to get back to blacksmithing again. Thank you so much Dr. Derrington and all you staff for the wonderful and amazing job. I can not be more grateful and blessed to have found you. There is not enough stars to give you an excellent rating. God bless you all!

Having had previous spinal surgery, I wanted to strengthen and maintain the adjacent vertebrae. Dr. Derrington clearly explained the Spinal PRP Treatment and answered all my questions. After the procedure his staff gave me clear recovery instructions and phased exercises. A couple months later I am feeling much better. Overall a great experience.

I was frequently awakened in the night with intense pain in my upper arm and shoulders. I would have to get up, sit in a chair with my arm hanging by my side until the pain eased off and I would then try to go back to sleep. I was becoming very sleep deprived. I experienced pain in both shoulders with ordinary daytime activities.
I found Dr Stephen Derrington of Derrington Orthopedics to be kind and compassionate about my situation. After an evaluation, he recommended PRP procedures on both shoulders.
It has been 2 months since the procedures and I’m so excited to be PAIN FREE and sleeping through the night. I’m thrilled to have my life back doing the things I love. I’m back to hiking in the mountains.
I found Derrington Orthopedics to be a warm, welcoming environment where I felt everyone working with me had my best interests in mind.
I would highly recommend Dr Stephen Derrington to anyone experiencing pain. Kudos to Dr Stephen for giving me my life back!

I have done a lot of research on stem cell and regenerative doctors. Dr. Darringer's office was so helpful. His video was informative, and I can see is a very caring doctor, and that he is very knowledgable. He focuses on Regenerative Medicine as his one service. We are looking forward to seeing him!

In 2019, I had a full knee replacement on my left leg, a scar of about 7-8 inches long and was on disability for 90 days. Needless to say, even though it gave me relief I just wished I would've known Dr. Derrington then as an alternative to surgery.
I've been under his care since the beginning of 2022 treating me for my right knee. He has done stem cell therapy and PRP treatments and has helped me tremendously. Thus, avoiding another full knee replacement. I was on my feet in 2 days after the procedures. I've been back to taking my dog for walks around the neighborhood, to the parks, and the beach. It's so nice to be able to go outside and enjoy the outdoors once again.
Thank you and I appreciate you Dr. Derrington. You're highly recommended!!

I was extremely impressed and beyond satisfied with my visit to Dr. Derrington. Over a year ago I was diagnosed with tendonitis in my left wrist and being left handed it was extremely painful. My previous Orthopedic doctor just pushed on my wrist and then proceeded to inject my wrist with a cortisone shot. I was in and out in 5 minutes. Fast forward to a week ago when I had an appointment with Dr. Derrington because the pain in my wrist came back and doing everyday tasks was painful. I was expecting a visit like the one I had previously and let me say this visit was anything but the quick in and out like my visit with my previous Orthopedic doctor. Dr. Derrington used an ultrasound machine not only on my left wrist that I have been having issues with, he looked at my right wrist as well and showed me the difference between the 2 wrists. He explained the differences between both and informed me that the tendon sheath was also causing my pain. He also did a cortisone injection in my wrist but he actually used the ultrasound as a guide to make sure he was injecting the correct area. I am beyond impressed with not only Dr. Derrington but his whole staff. I would recommend him to anyone needing an Orthopedic doctor. Thank you Dr. Derrington and staff for the quality care and making me feel like a human and not a number.

I am so grateful for Dr. Derrington! I struggled for years with my knee never feeling "right" after ACL/meniscus/bone graft surgeries. Dr. Derrington didn't just provide the injection - it was a plan to get myself healthy and back to being at peak performance. I am a CrossFit/mountain bike/snowboarding/skiing/climbing/surfing, etc. athlete - and this is the strongest I've felt!

I am a professional fighter and have seen my fair share of injuries, injections and treatments. One of the most significant injuries I sustained was to my neck in April during one of my fights. I suffered a really bad stinger that left my entire arm numb and unable to use during the duration of the fight, and found myself in the ER immediately following the end. I couldn’t turn my head for quite a while and did suffer some nerve damage in my shoulder from the fall. Through physical therapy and PRP injections from Dr. Derrington, I’ve been able to recover fully and am back competing. Even my physical therapy doctors were amazed at how well my body responded to PRP. I am a huge believer in this treatment and will be continuing it for my other injuries. I’m happy to have Dr. Derrington as part of my team!

I suffered a disc herniation working out, I thought it was the end of the world for me because it’s a big part of my daily life. Surgery was the last thing I even wanted to entertain as I knew it wasn’t realistic for me. Dr. Derrington spoke to me about alternative options and gave me comfort when trying to decide that PRP was the option for me. It has been 9 months and the best decision for me. I am able to work out with zero pain. I went from not being able to pick up anything from the ground and sleeping uncomfortably to now being and feeling so strong. I’m forever grateful for him and always try to send people to him. Highly recommend him and his office. 💛

I highly recommend Derrington Orthopedics and the PRP injection as an alternative to cortisone shots. I had damage to my tendon in my shoulder due to impingement and poor mechanics when working out. I had injured it multiple time over the years, and for months it was getting worse. I was unable to get dressed, reach into high cupboards to pull out heavy items, do everyday chores, or throw a ball without pain. I was unable to do pushups, bench press, and other exercises I had been able to do in the past. 8 weeks after the injection (which initiated the healing), physical therapy, and using better mechanics while working out, I am pain free. I can do pushups and bench press again and all of my everyday tasks without pain. It has been awesome! Thank you to Dr. Derrington and his team!

Dr. Derrington and his team were great! Very professional and took time with me to make sure I was comfortable with the platelet therapy on my torn meniscus. I am about two months out from the procedure and doing quite well, able to hike, walk normally and use the elliptical machine again. I am very happy that I found Dr. Derrington and this procedure as an alternative to jumping into surgery.

I tore my meniscus 05/2022 and after doing research on options, I decided on the PRP procedure. During my research I found out that a large % of meniscus repairs end up having the meniscus being removed. I didn't want to risk this happening to me and honestly like the idea of my own body repairing itself (with my own PRP).
Don't expect immediate results and for me improvement was gradual but significant at 3 months.
This may not be for everyone but I'd recommend at least a consult with Dr. Derrington before you schedule that surgery.

Dr Derrington is kind, caring and compassionate. He truly listens to you and works to tailor treatment to your specific needs. I underwent PRP for severe tennis elbow. I couldn’t have trusted anyone one else he is simply the best. And his staff is just exceptional! Now on to my recovery phase and being pain free. It’s nice to know he’s with you every step of the way to giving you your life back where other treatments have failed. Truly grateful!

PRP therapy is life changing! I’m 8 weeks pain free for the first time in years. I’m 52 years old and was diagnosed with disc degeneration 13 years ago. I’ve tried everything to ease the pain, including disc fusion surgery (C4 to C5 and C5 to C6). While the surgery was a “success” it did not ease the pain. I thought “this is it, there’s nothing more I can do”. Boy was I wrong…I wish I had known about PRP sooner. I am so grateful to Dr Darrington for literally giving me my life back. I highly, highly, highly recommend this therapy for anyone with chronic pain.
