Trial Summary

Will I have to stop taking my current medications?

You will need to stop taking any prescription or over-the-counter pain and anti-inflammatory medications for 7 days before any visit. If you are on anticoagulation therapy, it must be stopped before the injection.

What data supports the effectiveness of the treatment Adipose Derived (AD) Stromal Vascular Fraction (SVF) for knee osteoarthritis?

Research shows that injections of stromal vascular fraction (SVF) from fat tissue can be safe and effective for treating knee osteoarthritis, with studies reporting noticeable improvements in pain and joint function over time.12345

Is fat cell injection for knee osteoarthritis safe?

Research shows that injections of adipose-derived stromal vascular fraction (SVF) cells for knee osteoarthritis are generally safe, with studies reporting minimal complications and good clinical outcomes in the short to medium term.13467

How is the treatment Adipose Derived Stromal Vascular Fraction (SVF) unique for knee osteoarthritis?

This treatment is unique because it involves injecting a patient's own fat cells, specifically the stromal vascular fraction (SVF), directly into the knee joint. This approach is thought to provide mechanical support, reduce inflammation, and promote tissue repair, which is different from traditional treatments that mainly focus on pain relief and inflammation control.23489

What is the purpose of this trial?

This is a prospective, non-randomized, interventional, dual site, before-after clinical trial to determine feasibility and safety of a single injection of autologous Adipose Derived (AD) Stromal Vascular Fraction (SVF) for the treatment of knee Post Traumatic Osteoarthritis (PTOA).

Eligibility Criteria

This trial is for adults aged 18-45 who've had significant knee trauma or surgery between 1 and 20 years ago, leading to Post-Trauma Osteoarthritis (PTOA). They should have ongoing knee pain despite trying at least two treatments like medication or physical therapy. Participants need a BMI under 35, speak English, and be able to attend follow-up visits. Pregnant women, tobacco users, those with recent knee injections or certain medical conditions are excluded.

Inclusion Criteria

  • Adipose Derived (AD) Stromal Vascular Fraction (SVF)
Trial Overview The trial is testing the safety and feasibility of a single injection of autologous Adipose Derived Stromal Vascular Fraction (SVF) in treating knee PTOA. It's a before-after study conducted at two sites where participants' own processed fat tissue is used to potentially repair their injured knees.

Findings from Research

The study demonstrated that injecting autologous adipose-derived stromal vascular cells (SVF) into osteoarthritic knees is safe, with no reported adverse events such as infections or pain flares in 6 patients treated over a year.
Patients experienced significant pain reduction and improved function, as shown by better scores on the Visual Analog Scale (VAS) and the Western Ontario and McMaster Universities Arthritis Index (WOMAC) at 3 months and maintained these improvements at 1 year.
Adipose Derived Stromal Cell (ADSC) Injections for Pain Management of Osteoarthritis in the Human Knee Joint.Fodor, PB., Paulseth, SG.[2022]
Adipose-derived stem cell (ADSC) or stromal vascular fraction (SVF) injections are safe and show good clinical and radiological outcomes for knee osteoarthritis treatment, with a low complication rate of 16.15% for minor issues.
The study indicates that ADSCs and SVF can lead to promising improvements in knee osteoarthritis symptoms within 12-24 months, but highlights the need for more standardized follow-up and comparisons with other treatments to confirm efficacy.
Autologous adipose stem cell therapy for knee osteoarthritis: where are we now?Biazzo, A., D'Ambrosi, R., Masia, F., et al.[2021]
Intra-articular injection of adipose-derived stromal vascular fraction (SVF) cells in 57 patients with knee osteoarthritis showed significant improvements in knee extension and pain scores over a 12-month follow-up period, indicating its efficacy as a treatment.
The treatment led to better clinical outcomes, as measured by the WOMAC, VAS, and KOOS scores, with no significant changes in the hip-knee-ankle angle, suggesting that SVF cell therapy is a promising and innovative approach for managing knee osteoarthritis.
