Trial Summary

Do I need to stop my current medications to join the trial?

The trial does not specify if you need to stop taking your current medications, but it does mention that treatments like low dose Aspirin and Plavix are allowed. If you are on oral anticoagulants or heparin therapy, you may not be eligible to participate.

What data supports the effectiveness of the treatment Bone Marrow Aspirate Concentrate (BMAC) for knee osteoarthritis?

Research shows that BMAC, which includes special cells called mesenchymal stem cells, is a promising treatment for knee osteoarthritis, with studies indicating it can help improve symptoms and function in affected patients.12345

Is bone marrow aspirate concentrate (BMAC) safe for treating knee osteoarthritis?

Research on bone marrow aspirate concentrate (BMAC) for knee osteoarthritis suggests it is generally safe for use in humans, with studies focusing on its application for joint conditions.23678

How is the treatment Bone Marrow Aspirate Concentrate (BMAC) unique for knee osteoarthritis?

Bone Marrow Aspirate Concentrate (BMAC) is unique for knee osteoarthritis because it involves injecting a concentrate of bone marrow cells directly into the knee joint, which provides growth factors that help reduce inflammation and promote tissue repair. Unlike other treatments, BMAC uses the body's own cells to potentially improve joint function and alleviate symptoms.23678

What is the purpose of this trial?

The purpose of the ACCELERATE3 trial is to assess the efficacy of a single intra-articular (IA) injection of autologous BMAC, in one or both knees, compared to a single IA injection of Standard of Care (SOC) in patients with mild to severe knee OA.

Findings from Research

In a study of 233 patients with knee osteoarthritis, a single intra-articular injection of bone marrow aspirate concentrate (BMAC) led to significant pain reduction, with the numeric pain scale decreasing from 8.33 to 4.49 after treatment.
The procedure was found to be safe, with no complications reported, and resulted in improved knee function as indicated by an increase in the Oxford knee score from 20.20 to 32.29 over an average follow-up period of 11 months.
Effectiveness of a single intra-articular bone marrow aspirate concentrate (BMAC) injection in patients with grade 3 and 4 knee osteoarthritis.Themistocleous, GS., Chloros, GD., Kyrantzoulis, IM., et al.[2022]
Bone marrow aspirate concentrate (BMAC) injections significantly improve pain and patient-reported outcomes in knee osteoarthritis, with 94.4% of outcomes showing improvement over a mean follow-up of 12.9 months across 299 knees.
Despite its effectiveness, BMAC did not show clinical superiority over other treatments like platelet-rich plasma or microfragmented adipose tissue, and its high cost may limit its use compared to other therapies.
Bone Marrow Aspirate Concentrate for the Treatment of Knee Osteoarthritis: A Systematic Review.Keeling, LE., Belk, JW., Kraeutler, MJ., et al.[2022]
In a study of 55 patients with knee osteoarthritis, a single injection of autologous bone marrow aspirate concentrate (BMAC) led to significant improvements in patient-reported outcomes, including Tegner, VAS, and WOMAC scores.
The results suggest that BMAC is a beneficial and safe treatment option for knee osteoarthritis, as all measured outcomes showed statistically significant improvement from baseline to follow-up.
