Could your own fat cells ease hip arthritis pain?
NCT ID NCT02844764
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether injecting a patient's own stem cells (from fat) and platelet-rich plasma into the hip joint can reduce pain and inflammation from osteoarthritis. The trial starts with 50 people and plans to expand to 4,000. Researchers will measure pain, quality of life, and look for cartilage regrowth on MRI.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- StroMed (a patient's own stem cells from fat) and platelet-rich plasma (PRP)
- What this could lead to
- If it works, this could offer a way to manage hip osteoarthritis pain and possibly regrow cartilage without surgery.
- What could go wrong
- This is an early phase 2 study with only 50 initial patients, so results are not yet proven. The treatment involves injections, which carry risks like infection or pain at the injection site.

Inclusion Criteria: 1. Patients with indication of Osteoarthritis. Can be from degeneration or chronic injury. 2. Patients range from 18-90 years of age. 3. Patients must be able to comply with treatment plan, laboratory tests and periodic interviews. 4. Patients with adequate renal function, Creatinine ≤ 1.5 mg/dl. 5. Patients with adequate cardiac and respiratory function. 6. Patients with adequate blood coagulation activity, PT(INR) \< 1.5, APTT 7. Patients must have adequate immune system function, with no known immunodeficiency disease. 8. Greater than 6 months hip pain with the index side (left or right). Exclusion Criteria: 1. Neoplastic cancer within 5 years prior to screening, except for cutaneous basal cell or squamous cell cancer resolved by excision 2. Presence of clinically significant acute or unstable cardiovascular and cerebrovascular (stroke). 3. Diagnosis of a transient ischemic attack in the 6 months prior to screening. 4. Patients infected with hepatitis B, C or HIV. 5. Patients with Body Mass Index (BMI) \> 40kg/m2 6. Presence of active infection. 7. Any other illness, psychiatric disorder, alcohol or chemical dependence that in the opinion of the investigator would render a patient unsuitable to participate in the study. 8. Conditions/therapies/factors which could confound or interfere with the evaluation of pain/mobility including, but not limited to: * Treatments with strong opioid drugs in the previous 4 weeks for other pain rather than hip osteoarthritis * Corticosteroid injection at treatment site within 1 month * Consistent use of NSAIDs within 48 hours of procedure.
