Body area
Knee
The knee has the largest body of human SVF research, including RCTs and several systematic reviews focused on pain and function outcomes.
Research overview
Most studies enrol people with moderate knee osteoarthritis and use WOMAC, VAS, or KOOS scores over 6–24 months of follow-up.
Many studies report reduced pain scores, but MRI-based cartilage structural outcomes remain inconsistent.
Systematic reviews
Several systematic reviews find symptom outcomes trending in the same direction, but study quality varies and risk of bias remains.
Limitations
Sample sizes are often modest, follow-up short, cell preparation non-standardised, and many studies lack placebo controls.
