Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||35 Years - 85 Years|
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.
The person who is responsible for the scientific and technical direction of the entire clinical study.

The disease, disorder, syndrome, illness, or injury that is being studied.
Initial study procedures include baseline evaluation of medical history, knee history, knee examination, medication use, MRI, and subject-reported outcomes. Each osteoarthritic subject will undergo withdrawal of knee joint synovial fluid for each knee being treated (0.3-0.5 ml) which will be analyzed by the research laboratory via multiplexed enzyme linked immunosorbent assay (ELISA) and dimethylmethylene blue assay (DMMB) at pre-injection (2-8 days before Regenexx-SD treatment). Documentation of osteoarthritic joint characteristics and injection procedure details will be recorded throughout the study. The unaffected knee joint will undergo no treatment, but bilateral knees may be treated. The objective of this study is to correlate the pre- Regenexx-SD treatment levels of pro-inflammatory cytokines, anti-inflammatory cytokines, matrix metalloproteinases, and catabolic articular cartilage breakdown products in the osteoarthritic knee synovial fluid microenvironment with 6 month post-treatment clinical outcomes. This data will be used to establish a predictive a priori testing "model" to determine if a patient is a good candidate for the Regenexx-SD treatment based on their initial osteoarthritic knee synovial fluid microenvironment phenotype. It may also be used to determine if the micro-environment can be altered to improve outcome before receiving Regenexx-SD. Incidence of post-operative complications, adverse events, re-injections, and surgical intervention and change in pain score will be considered while determining these direct and indirect associations upon completion of the Regenexx-SD treatment. Components of the synovial fluid will be correlated to post-treatment clinical outcomes, which include several self-reported questionnaires as well as assessment of post-injection complications, adverse events, re-injections and surgical interventions. Patient reported questionnaires include IKDC Subjective Knee Evaluation, Lower Extremity Function Scale, Pain Scales and a Modified Single Assessment Numeric Evaluation (SANE).
Experimental: Knee Synovial Fluid collection before Regenexx-SD
Measure components of knee synovial fluid 2-4 days before the Regenexx-SD treatment.
Procedure: - Bone Marrow Concentrate treatment
Correlate patient outcomes 6 months after receiving the Regenexx SD treatment with measurements of synovial fluid collected before treatment
