Trial Summary

What is the purpose of this trial?

This trial is testing an injection of a patient's own processed fat tissue to treat knee pain and improve function in people with moderate knee osteoarthritis. The fat tissue is thought to help by cushioning the joint and possibly aiding in healing. This treatment has been studied for its potential to improve pain and function in patients with knee osteoarthritis.

Do I have to stop taking my current medications for the trial?

Yes, you may need to stop certain medications. You must stop using over-the-counter pain medications like Acetaminophen or NSAIDs for 7 days before any follow-up visit, except for one 'baby aspirin' per day for heart health. You also need to stop prescription pain or anti-inflammatory medications during the study, except for Tramadol right after the procedure. Additionally, you must avoid NSAIDs for 7 days before and 2 weeks after the injection.

What data supports the idea that Fat Cell Injections for Knee Osteoarthritis is an effective treatment?

The available research shows that Fat Cell Injections, also known as Microfragmented Adipose Tissue (MFAT), can be effective for treating knee osteoarthritis. One study found that patients experienced reduced pain and improved quality of life one year after receiving the treatment. Another study compared MFAT to Platelet-Rich Plasma, another treatment for knee osteoarthritis, and suggested that MFAT might offer better long-term benefits. Additionally, when combined with a procedure called arthroscopic debridement, MFAT provided functional improvements in patients. Overall, these studies indicate that MFAT can help reduce symptoms and improve knee function in people with osteoarthritis. ^{1 2 3 4 5}

What safety data exists for fat cell injections in knee osteoarthritis treatment?

The safety data for autologous microfragmented adipose tissue (MFAT) injections in knee osteoarthritis treatment indicates that while there is potential for early clinical improvement, there are also notable adverse events. In a study involving 64 subjects, an inflammatory reaction was reported in 79% of knees, which resolved spontaneously within an average of 16.6 days. This suggests that while MFAT injections can be safe, they may cause temporary inflammation. The treatment showed a mediocre response rate of 45% at 12 months, indicating that patient selection is crucial for better outcomes. ^{1 2 3 4 6}

Is Microfragmented Adipose Tissue a promising treatment for knee osteoarthritis?

Yes, Microfragmented Adipose Tissue (MFAT) is a promising treatment for knee osteoarthritis. Studies show that it can reduce pain, improve joint function, and enhance quality of life for patients. It works by using special cells from your own fat to help repair and regenerate knee tissues. ^{1 2 3 4 7}

Treatment Details

Interventions

• Microfragmented Adipose Tissue (Other)

Trial Overview The study compares the effects of a single injection of Microfragmented Adipose Tissue (MFat) using Lipogems® against a saline solution in reducing pain and improving function in patients with moderate knee osteoarthritis.

Participant Groups

Group I: Micro Fragmented Adipose Tissue (MFat) Experimental Treatment 1 Intervention

Injection of Microfragmented Adipose Tissue derived using Lipogems® Kit The cases assigned to this group will be injected intra-articularly with Lipogems®. The patients will undergo lipoaspiration of their own adipose tissue for MFat then this MFat will be injected intra-articularly in the knee. It will be administered once at the baseline visit of the study.

Group II: Saline Injection Active Control 1 Intervention

The cases assigned to this group will be injected intra-articularly in the knee with saline. It will be administered once at the baseline visit of the study.

Findings from Research

A single injection of autologous microfragmented adipose tissue (MFAT) significantly improved clinical outcomes, including pain and quality of life, in 75 elderly patients with knee osteoarthritis over a two-year follow-up period.

The best results were observed in patients with early-stage osteoarthritis (KL grade 2), but overall, 88.3% of treatments showed significant functional improvement across all grades of knee OA, suggesting MFAT is a safe and effective alternative treatment.

In a study of 110 knees, a single ultrasound-guided injection of microfragmented adipose tissue (MFAT) significantly reduced pain (VAS score improved from 70 to 30) and enhanced functionality (OKS score improved from 25 to 33.5) in patients with knee osteoarthritis over a 12-month period.

No adverse events were reported during or after the procedure, indicating that MFAT injections are a safe treatment option for knee osteoarthritis, with promising improvements in patient quality of life (EQ-5D score improved from 0.62 to 0.69).

In a study involving 118 patients with knee osteoarthritis, both microfragmented adipose tissue (MF-AT) and platelet-rich plasma (PRP) injections led to significant improvements in knee function and pain relief over 24 months, with no notable differences in outcomes between the two treatments.

While MF-AT and PRP showed similar efficacy, a higher percentage of patients with moderate to severe OA in the MF-AT group achieved clinically meaningful improvements in knee function at 6 months, suggesting a potential advantage for certain patients.

In a study of 71 patients with early hip osteoarthritis, injections of autologous micro-fragmented adipose tissue (MFAT) led to significant clinical improvements, with 28 patients not requiring further treatment after an average follow-up of 29 to 41 months.

The Oxford Hip Score improved by an average of 6.9 points post-treatment, indicating that MFAT injections can be an effective option for managing symptoms in early to moderate hip osteoarthritis.

In a randomized controlled trial involving 78 patients with knee osteoarthritis, the combination of microfragmented adipose tissue (mFAT) and arthroscopic debridement (AD) significantly improved functional scores compared to AD alone at both 6 months and 24 months follow-up.

The mFAT treatment also resulted in better MRI outcomes, indicating enhanced tissue healing, and was associated with lower T2-mapping scores in knee compartments, suggesting improved cartilage health.

Micro-fragmented adipose tissue (mFAT) associated with arthroscopic debridement provides functional improvement in knee osteoarthritis: a randomized controlled trial. Ulivi, M., Meroni, V., Viganò, M., et al.[2023]

A single intra-articular injection of autologous microfragmented adipose tissue (MFAT) showed a short-term therapeutic response rate of 64% at 3 months and 45% at 12 months in 64 patients with symptomatic knee osteoarthritis, indicating early clinical improvement but a decline in effectiveness over time.

The study found that the presence of bone marrow lesions negatively impacted the therapeutic response rate, suggesting that assessing these lesions could help identify patients who may benefit more from MFAT treatment, potentially increasing the response rate to 70% at 12 months.

In a study of 110 patients with knee osteoarthritis, both microfragmented adipose tissue (MFAT) and bone marrow aspirate concentrate (BMAC) injections led to significant improvements in pain and function, as measured by various questionnaires over a follow-up period averaging 1.8 years for BMAC and 1.1 years for MFAT.

There was no significant difference in the effectiveness of pain relief and functional improvement between the two treatment groups, indicating that both MFAT and BMAC are viable options for treating symptomatic knee osteoarthritis.
