I had a partial tear in my bicep tendon and did not have time to recover from shoulder surgery, which is generally 4 months. I opted instead to have stem cell injections. Dr. Lewis and his staff were very professional and explained the procedure thoroughly. After 2 months, I am back to swimming a mile every other day and bicycling almost every day. I would highly recommend Northwest Center for Regenerative Medicine to anyone who is a good candidate for this procedure.

I’ve been having terrible migraines and neck pain since I was 12 yrs old. Dr. Lewis quickly identified the main root of my migraines which were stemming from an old neck injury. He immediately began a combination of Regenerex and other treatments. These treatments have radically diminished the pain in my neck and decreased the frequency and intensity of my migraines. Dr. Lewis took the time to listen, explain, and diagnose the problem. I’ve had a great experience, and would highly recommend him to treat your pain.

Dr. Lewis has helped me get back to my active lifestyle! I was having so much pain in my lower back I was not able to garden or work on improvements to my property. At one point I could barely walk and in so much pain I had to be taken to ER for pain injections! I heard about Dr. Lewis from a co-worker and scheduled an appointment. Dr. Lewis evaluated my condition and recommended treatment. After the treatment he recommended (3 months ago) I am shoveling, fence building, moving bales of hay without even thinking about my back! NO PAIN! THANK YOU DR. LEWIS! I was so worried I would have to have surgery. That is no longer a worry!

Dr. Lewis and Amanda were always very professional and courteous. He did a thorough examination and made recommendations for the areas to receive platelet injections. The primary goals were my knees and neck with improvement in all those areas. I also had injections in one hip and shoulder but had minimal to no pain relief. However, am very grateful for some reduction in pain which is more than I an say for many other medical procedures I've had! Thank you Dr. Lewis and Amanda!

I have been a patient of Dr Lewis for several years and always find him to be kind, thoughtful, and communicative. The staff are all professional and easy to work with.

Regenexx Stem Cell and Platelet Therapy is in a class by itself. No magic pixie dust here, just effective treatment based on real science and data. Avoiding painful surgery on my cervical spine was a priority for me. Dr. Jamie Lewis and his team at Northwest Center for Regenerative Medicine (the only Regenexx Clinic in eastern Washington/north Idaho area) clearly explained my treatment options and how to get the best results possible. The platelet procedure has helped tremendously with pain and mobility issues and I look forward to enjoying an active summer in the beautiful northwest!

I had a platelet lysate procedure with Dr. Lewis on my cervical & lumbar spine and SI Joints three days ago. Last night I was able to lay my head on my husband's chest while we watched a movie (haven't been able to do that in months). Today, I'm organizing my kitchen cupboards.

I am a 62 year old male patient that has been very active throughout my life. In the past several years I noticed an overwhelming increase in the pain I feel in my knees and shoulders. The pain in my knees, primarily my left knee, had gotten to the point where it was interfering with my day to day living, dramatically limiting me to what I could do. I had received some information on regenerative therapy and did some researching on my own. I contacted Northwest Center for Regenerative Therapy and set up an appointment to have a procedure on my left knee. On August 9, 2018 Dr. Lewis performed a PRP procedure on my left knee. It has been five months and I could not be happier, I not only am pain free but I have my life back. I'm hiking regularly and I work out at the gym almost daily. Thank you Dr. Lewis for giving me my life back it has been nothing short of miraculous. P.S I just recently had both my shoulders done and can't wait to see how they turn out.

I had my nine week follow up appointment today after having stem cell replacement therapy for my knee. I am so thankful for Dr Lewis, his awesome team, and this procedure! Prior to the stem cell therapy I could often barely walk. Today I am pain free, and my knee feels like it did 20 years ago! I can now sleep again at night without pain or discomfort which is HUGE, and am back in the outdoors again doing the things I love. So grateful to Northwest Center for Regenerative Medicine and their staff! I highly recommend them!

I have been limited by elbow pain since 2011. Had an MRI on my elbow in 2017 which didn’t show much and ortho doc offered me a cortisone shot (no thank you). Saw Jamie Lewis, MD (Physiatrist) at Northwest Center for Regenerative Medicine on May 14. He looked at my elbow MRI and elbow/neck/shoulder, suspected my pain stemmed from my neck and shoulder and ordered the appropriate MRI which I had done on May 22. I received the MRI results explaining my pain and limitation on May 24. I’ve waited seven years for these answers. Thank you, Dr Lewis!Regenexx Platelet Therapy here I come. Procedure is scheduled for June 5th. “We’ll fix you.” -Christi Barker, R.N. #Physiatryismynewbreadandbutter #NWC4RMblastoff #Regenexxlifelonglove

Knee Stem Cell Therapy

If you have encountered an injury to the knee meniscus, cartilage, ACL or MCL ligaments, or have chronic knee pain due to a past injury or arthritis, you may be a good candidate for knee stem cell therapy or platelet rich plasma procedures. Traditional options for patients suffering from these issues include arthroscopic knee surgery to repair ligament tears, or total knee joint replacement. With both surgeries, months of rehab are required to regain strength and mobility, and the patient must be aware of and prepared for associated risks.

Shoulder Stem Cell Therapy

If you have encountered a rotator cuff tear, or experience pain related to shoulder arthritis, tendonitis, tendenosis, or bursitis, you may be a good candidate for a Regenexx Procedure. Shoulder surgery is particularly difficult due to the complexity of the joint. Post surgical recovery can be painful, requiring a lengthy rehab period to restore strength and mobility to the shoulder. As an alternative to shoulder surgery, Regenexx Procedures may help alleviate shoulder pain and restore joint damage with a non-invasive injection procedure. Patients typically experience little or no down time from the procedure.

Spine Stem Cell Therapy

Regenexx has many non-surgical platelet and adult stem cell based procedures developed to help patients avoid spine surgery and high dose epidural steroid side effects. Our decade of experience in regenerative treatments for spine pain allows us to address as many factors as possible to gain insight into the true cause of the problem. We identify the most probable sources of pain and select the most appropriate treatment options available. Only then can the natural healing process be initiated using the safest, least invasive procedure possible for a Regenexx Procedure.

Regenexx® Patented Stem Cell Procedures are the World's Most Advanced Stem Cell Procedures for Orthopedic Conditions

At Northwest Center for Regenerative Medicine, our #1 priority is to produce the best possible outcomes for our patients. And while our patented protocol is far more complex than you will find at other regenerative medicine clinics, we do not cut corners. Everything about your Regenexx experience is designed for results.

Stem cells live in all of us and they act as the repairmen of the body. However, as we age or get injuries, we sometimes can’t get enough of these critical repair cells to the injured area. The Regenexx Procedures help solve this problem by greatly increasing your body’s own natural repair cells, promoting healing. This is accomplished by harvesting cells from areas of your body known to be rich in mesenchymal stem cells and then concentrating those cells in a lab before precisely reinjecting them into the damaged area in need of repair.

Regenerative Medicine

We are proud to offer Regenexx. Regenexx procedures are the world’s most advanced bone marrow stem cell and blood platelet procedures for treating orthopedic injuries, arthritis and other degenerative conditions. Regenexx patented procedures use precise injections of your own stem cells or blood platelets to help your body’s ability to heal damaged muscles, tendons, ligaments, cartilage, spinal disc and bone.


Spine Procedures

Regenexx has a range of procedures developed to help patients avoid spine surgery and the side effects of epidural steroid injections. These procedures utilize the patient’s own natural growth factors or stem cells to treat bulging or herniated discs, degenerative conditions in the spine, and other back and neck conditions that cause pain. The origin of spine pain is often misidentified.

Hip Procedures

The Regenexx® family of hip surgery alternatives are breakthrough, non-surgical stem-cell treatments for people suffering from hip pain due to common injuries, hip arthritis, avascular necrosis, osteonecrosis, hip bursitis or other degenerative problems related to the hip joint. Regenexx bone marrow stem cell and blood platelet procedures offer a non-surgical treatment option for many patients who are considering elective surgeries to resolve their hip pain.


This health care practitioner performs one or more bone marrow stem cell therapies that have not yet been approved by the United States Food and Drug Administration. You are encouraged to consult with your primary care provider prior to undergoing a stem cell therapy.
