What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this study is to compare the clinical and functional outcomes of patients with mild to moderate arthroscopically confirmed osteoarthritis between the following two groups:1. Partial fat pad harvest with Adipose-Derived Stem Cell (ADSC) transplantation with standard arthroscopic treatment consisting of: partial meniscectomy, cartilage stabilization, loose body removal and selective synovectomy.2. Standard arthroscopic treatment (above) without cell transplant.

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

The trial protocol does not specify whether you need to stop taking your current medications. However, it mentions that participants should have tried anti-inflammatory medications as part of conservative therapy before joining the trial.

What safety data exists for stem cell and arthroscopy treatment for knee osteoarthritis?

The treatment involving adipose-derived stem cells (ADSCs) and arthroscopy for knee osteoarthritis has been shown to be safe across multiple studies. No serious adverse events were reported in trials involving ADSC therapy, either alone or combined with arthroscopic procedures. The studies consistently reported significant improvements in pain and function, with minimal complication rates. The treatment appears to be well-tolerated and effective in improving symptoms and potentially modifying disease progression.12345

Is the treatment of arthroscopic debridement with stem cell transplantation promising for knee osteoarthritis?

Yes, the treatment of arthroscopic debridement with stem cell transplantation shows promise for knee osteoarthritis. Studies suggest that it can improve pain and function, and even help regenerate cartilage in the knee, making it a potential option for preserving the joint in patients with knee osteoarthritis.34678

What data supports the idea that Stem Cell Transplantation + Arthroscopy for Knee Osteoarthritis is an effective treatment?

The available research shows that Stem Cell Transplantation combined with Arthroscopy is effective for treating knee osteoarthritis. One study found that patients with early knee osteoarthritis experienced significant improvements in their symptoms after receiving this treatment. Another study reported that patients with severe knee osteoarthritis had less pain and better function, along with cartilage regeneration, after undergoing the treatment. Additionally, a study showed that pain decreased by 83% and function improved by 84% after one year of treatment. These results suggest that this treatment can significantly improve symptoms and may even help preserve the knee joint in advanced cases.12349

Are You a Good Fit for This Trial?

This trial is for adults aged 35-70 with mild to moderate knee osteoarthritis who haven't had relief from physical therapy and anti-inflammatory meds. It's not for those outside the age range, with severe or little to no arthritis, prior fat pad injuries/surgeries, or recent knee surgeries.

Inclusion Criteria

Patient is scheduled to undergo one or a combination of the following procedures: Meniscal debridement or partial menisectomy, Meniscal repair that does not necessitate a different postoperative protocol from meniscal debridement or partial menisectomy, Removal of loose bodies, Chondroplasty, Synovectomy, Soft tissue releases for flexion or extension contracture, Diagnosis of pre-existing mild to moderate osteoarthritis of the medial or lateral femoral condyle (Kellgren-Lawrence Grade 2 or 3), < 6 months of knee pain or < 6 months of a significant exacerbation of existing knee pain, Physical examination findings consistent with the proposed surgical procedure, Failure of conservative therapy consisting of a minimum of 6 weeks of physical therapy and trial of anti-inflammatory medications, with or without concomitant bracing and/or injections
I am between 35 and 70 years old.

Exclusion Criteria

I am scheduled for knee surgery that is not major and does not change my recovery plan.
I am younger than 35 or older than 70.
My X-rays show I have no, mild, or severe arthritis.

What Are the Treatments Tested in This Trial?

Interventions

  • Arthroscopic debridement only
  • Arthroscopic debridement with stem cell transplantation
Trial Overview The study compares two treatments: one group receives standard arthroscopic treatment plus stem cells from their own fat tissue; the other gets just the standard treatment without stem cells. The goal is to see which method better improves knee function.

Published Research Related to This Trial

In a study of 52 patients with early knee osteoarthritis, the combination of autologous adipose-derived stem cell injections and arthroscopic debridement significantly improved knee function and reduced pain over an average follow-up of 15.3 months.
Patients with higher pre-operative pain levels (VAS score > 8) experienced greater improvements in clinical and functional outcomes, suggesting that this treatment may be particularly beneficial for those with more severe symptoms.
Preliminary results of autologous adipose-derived stem cells in early knee osteoarthritis: identification of a subpopulation with greater response.Schiavone Panni, A., Vasso, M., Braile, A., et al.[2020]
Intra-articular injection of autologous purified adipose tissue significantly reduced pain in knee osteoarthritis patients, with a 53% decrease after 1 month and an 83% decrease after 1 year, based on VAS scores.
The treatment also led to a 47% improvement in functional recovery after 1 month and an 84% improvement after 1 year, with no reported adverse effects, indicating both safety and efficacy over a 12-month follow-up period.
Intra-Articular Administration of Autologous Purified Adipose Tissue Associated with Arthroscopy Ameliorates Knee Osteoarthritis Symptoms.Caforio, M., Nobile, C.[2021]
In a study involving 30 participants with knee osteoarthritis, autologous adipose-derived mesenchymal stem cell (ADMSC) therapy was found to be safe, with no serious adverse events reported.
Both treatment groups receiving ADMSC injections showed significant improvements in pain and function after 12 months, and MRI results suggested that the therapy may help slow down disease progression.
