What You Need to Know Before You Apply

What is the purpose of this trial?

The proposed research study aims to evaluate the effects of autologous bone marrow aspirate concentrate (BMAC) on the development and progression of osteoarthritis (OA) in patients undergoing meniscectomy. This prospective, randomized, double-blind clinical trial will compare patient-reported outcomes, specifically IKDC scores between patients who receive BMAC post-meniscectomy and those who receive a saline control injection. The study will also compare physical examination, MRI, radiographs, and synovial fluid analysis. Our hypothesis is that those who receive the autologous BMAC injection after the procedure will have better outcomes than those who do not.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, if you have had a cortisone, viscosupplementation, or PRP injection in the last 6 weeks, you may not be eligible to participate.

Is BMAC safe for treating osteoarthritis?

Research on BMAC for osteoarthritis suggests it is generally safe for use in humans, with studies evaluating its safety alongside its effectiveness for joint treatment.12345

How is the BMAC treatment different from other treatments for osteoarthritis?

BMAC (Bone Marrow Aspirate Concentrate) is unique because it involves injecting a concentrate derived from a patient's own bone marrow into the affected joint, which provides growth factors with potential anti-inflammatory and tissue-repairing effects. Unlike other treatments, BMAC uses the body's own cells to potentially improve joint function and reduce symptoms.12467

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

Research shows that BMAC, which is a treatment made from a patient's own bone marrow, has shown promising results in reducing symptoms of knee osteoarthritis. It contains growth factors that help reduce inflammation and promote healing in the joints.12467

Are You a Good Fit for This Trial?

This trial is for adults over 18 with a painful meniscal tear confirmed by MRI and surgery, who need a meniscectomy. They must have mild to moderate osteoarthritis but no history of rheumatoid arthritis, recent infections requiring antibiotics, prior knee surgeries, or injections within the last 6 weeks. Pregnant individuals or those with diabetes, transplant history, decision-making impairments, recent cancer (except basal cell), or severe osteoarthritis are excluded.

What Are the Treatments Tested in This Trial?

Interventions

  • Autologous Bone Marrow Aspirate Concentrate
Trial Overview The study tests if injecting Bone Marrow Aspirate Concentrate (BMAC) after meniscectomy can slow down osteoarthritis progression compared to a saline injection. It's randomized and double-blind meaning neither patients nor doctors know who gets BMAC or saline. Outcomes will be measured through patient scores on knee function (IKDC), physical exams, MRIs, X-rays and joint fluid analysis.
How Is the Trial Designed?
2Treatment groups
Experimental Treatment
Placebo Group
Group I: Meniscectomy with Bone Marrow Aspirate Concentrate (BMAC)Experimental Treatment2 Interventions
Subjects will undergo the scheduled meniscectomy procedure. Following the procedure the investigator will make a small incision and create the marrow access channel in the proximal tibia. The experimental group will then have bone marrow harvested and BMAC will be prepared using a BMAC harvesting system. The automated centrifuge system rapidly concentrates cellular contents and growth factors in bone marrow aspirate using flow cytometry. The BMAC will be injected intra-articularly.
Group II: Meniscectomy with PlaceboPlacebo Group1 Intervention
Subjects will undergo the same meniscectomy procedure and will also have an incision and marrow access channel made in the proximal tibia, however no bone marrow will be harvested. The control group will have a placebo injection of saline into the affected knee.

Published Research Related to This Trial

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]
Bone marrow aspirate concentrate (BMAC) injections show promise for treating osteoarthritis (OA), with 22 studies involving 4626 patients indicating overall safety and low adverse events.
Most studies reported improvements in pain and function, but significant variability in study quality and methodology suggests that more rigorous, large-scale trials are needed to confirm BMAC's effectiveness in OA treatment.
Bone marrow concentrate injections for the treatment of osteoarthritis: evidence from preclinical findings to the clinical application.Cavallo, C., Boffa, A., Andriolo, L., et al.[2022]
A single injection of Bone Marrow Aspirate Concentrate (BMAC) significantly improved knee osteoarthritis symptoms, showing better results in pain and function compared to a cycle of 4 Autologous Conditioned Serum (ACS) injections over a six-month follow-up.
Both BMAC and ACS treatments were found to be safe and effective, but BMAC demonstrated greater efficacy in reducing pain and improving function as measured by the WOMAC index.
