Stem cell and PRP injections for musculoskeletal conditions are NOT FDA APPROVED. While research has shown that stem cell and PRP therapy may offer benefits to patients with orthopedic issues, many of these same studies conclude that further evaluation is needed from large, well-controlled clinical trials to verify possible benefits. We only treat orthopedic issues. We do not treat disease. We do not offer IV treatments.
We do not promise stem cell or PRP therapy as a cure for any condition. We provide stem cell and PRP therapy as a same day procedure, without manipulation, stimulation, or culturing of cells. Stem Cell and PRP therapy does not work for everyone. Results achieved by some patients may not be typical for other patients. There are no guarantees that this treatment will help you. All information on this website including reference to current research journals is for educational purposes only. There is controversy in the medical community about whether umbilical cord blood stem cells are alive or dead. You are encouraged to speak with your private medical doctor to help you decide if our treatments might be beneficial for you.

Preliminary research suggests that bone marrow concentrate (BMC), which contains mesenchymal stem cells and platelets, is a promising treatment for knee osteoarthritis. The aim of this study was to build upon this preliminary research by reporting the short-term progress of fifteen patients (twenty knees) with knee osteoarthritis through four BMC treatments.
Patients were advised to receive BMC injections approximately two weeks apart. The last follow-up was conducted a mean 86 days after the first treatment. Baseline and post-treatment outcomes of resting pain, active pain, lower functionality scale, and overall improvement percentage were compared after each treatment.
On average, patients experienced a 2.1 decrease in resting pain, a 3.5 decrease in active pain, and a 9.8 increase in functionality score at the final follow-up. Additionally, patients reported a mean 67% total overall improvement at study conclusion. Outcomes at the final follow-up after the fourth treatment were statistically significant compared to outcomes at baseline, after first treatment, after second treatment, and after third treatment.
These results are promising, and additional research with a larger sample size and longer follow up is needed to further examine the treatment effectiveness of multiple BMC injections for knee osteoarthritis.
Preliminary Data: The table below illustrates 20 osteoarthritic knees that were tracked through four stem cell treatments.
Short-Term Outcomes in Treatment of Hip Osteoarthritis with Four Bone Marrow Concentrate Injections: A Case Series

The use of mesenchymal stem cells from bone marrow concentrate (BMC) has become an increasingly popular option as an alternative to total joint replacement. Although there is evidence to support the use of BMC injections to improve quality of life for patients with knee osteoarthritis (OA), there is limited evidence to support its use in patients with hip OA. This case series provides the short-term outcomes of four patients who each underwent four BMC injections. On average, the last follow up was administered three and half months after the first injection. The results show that patients experienced decreased resting and active pain compared to baseline and mean 72.4% total overall improvement. Patients also reported less difficulty in performing daily activities following the procedure. These encouraging results warrant further research to better understand the effects of BMC injections on hip OA.
Preliminary Results: The table below illustrates the baseline and post-treatment outcomes of four osteoarthritic hips that underwent four stem cell treatments
Treatment of Lower Back Pain with Bone Marrow Concentrate
Lower back pain can be a debilitating condition that is often caused by ligament and fascial sprains, and muscle strains. Even though the diagnosis may be a herniated disc, facet arthropathy, degenerative disc disease, spinal stenosis, scoliosis, spondylosis, spondylolisthesis, or other pathology, we have found for the past twenty years, with thousands of successfully treated patients, that the actual pain generator may not even be noted in the diagnosis. With the risk of adverse complications of surgery and ineffectiveness of epidural injections, bone marrow concentrate (BMC) offers a promising treatment to treat lower back pain. BMC contains mesenchymal stem cells that have the ability to differentiate into muscle, cartilage, and bone, in addition to releasing trophic factors that enhance tissue regeneration. The four patients included in this study underwent at least one BMC injection to the entheses of muscles, fascia, and ligaments surrounding the lumbar spine. At one-year follow-up all four patients experienced a decrease in resting and active pain. Patients also reported a mean 80% total overall improvement and were able to perform daily activities with less difficulty. These encouraging results warrant further investigation of the full potential of BMC injections for lower back pain.
Preliminary Data: The table below illustrates the baseline and post-treatment outcomes of four lower back pain patients that underwent stem cell procedures
Platelet Rich Plasma Therapy on unresolved chronic wrist pain
Orthopedic & Muscular System: Current Research (March 2019).
The objective of our study, was to share with the medical community our observations on pain and function in 6 patients who had their wrists (one patient had both wrists treated), who underwent PRP injections to the ligaments and joints of the wrist. We hypothesize that by strengthening the ligaments and regrowing tissue within the wrist joints, we may provide patients improved quality of life and pain relief.
These findings have been summarized here:
- Platelet-Rich Plasma (PRP) is a minimally invasive surgical alternative that uses components from a patient’s own blood to regrow tissue and relieve pain. This study investigated the clinical effect of PRP on unresolved wrist pain.
- Six patients and seven wrists underwent a series of two to four PRP injections for unresolved wrist pain.
- Outcomes of resting pain, active pain, upper functionality scale, and overall improvement percentage were measured and compared to baseline.
- The final follow-up was performed an average of 6.57 months after injection.
- All patients included in the study experienced decreases in pain and improvement in functionality score at final follow-up.

Treatment of Unresolved Lower Back Pain with Platelet-Rich Plasma Injections
Background: Platelet-Rich Plasma (PRP) is a non-invasive modality that has been used to treat musculoskeletal conditions for the past two decades. Based on our research, there were no publications that studied the effect of PRP on unresloved lower back pain. The aim of this study was to report the clinical outcomes of patients who received PRP injections to treat unresolved lower back pain.
Methods: 67 patients underwent a series one, two, or three PRP injections into the ligaments, muscle, and fascia surrounding the lumbar spine. Patients who received two treatments received injections a mean 24 days apart and patients who received three treatments received injections a mean 20.50 days apart. Baseline and posttreatment outcomes of resting pain, active pain, lower functionality scale, and overall improvement percentage were compared to baseline and between groups.
Results: Patients who received one PRP injection reported 36.33% overall improvement and experienced significant improvements in active pain relief. These same patients experienced improvements in resting pain and functionality score, yet these results were not statistically significant. Patients who received a series of two and three treatments experienced significant decreases in resting pain and active pain and reported 46.17% and 54.91% total overall improvement respectively. In addition, they were able to perform daily activities with less difficulty than prior to treatment.
These results demonstrate that PRP injections may be a viable conservative approach to treat lower back pain. Additional research is needed to confirm these findings.

There is controversy in the medical community about umbilical cord blood stem cells. Some insist that the injectable solution contains abundant live umbilical cord blood stem cells. Some suggest that the stem cells are not alive. Some research shows that stem cells may release cytokines and growth factors that awaken native stem cells. We also use PRP and bone marrow depending on the patient’s pathology and requirements. We are in the process of doing a large study on cord blood stem cells to ascertain which treatments are the most successful. Short term results show cord blood stems cell and bone marrow concentrate to be statistically equal in efficacy on the scales we record..
