Torn meniscus treatment without surgery


The meniscus is essential to knee function. There are two menisci in each knee, lining the inner surface and absorbing the shock in between the upper and lower leg bones. A torn meniscus is a common sports injury and source of chronic pain. The standard therapy for a torn meniscus is a partial or total meniscectomy – in other words they take some or the entire meniscus out.  But as we already stated, the meniscus acts as a shock absorber in the knee. It also provides stabilization. So removing a torn meniscus removes shock absorption and stability. The results are instability in the knee, extra force on the cartilage of the knee, and inevitable degeneration of cartilage leading to osteoarthritis of the knee. Clearly a meniscectomy is not the answer to a torn meniscus.

Stem Cell Therapy for Torn Meniscus

A  group of researchers at Hiroshima University in Japan sudied surgical alternatives to a torn meniscus1. They were aware of the poor outcome of meniscectomies and of alternative treatments. They did, however, hear of the promising results of using mesenchymal stem cells in regenerating and repairing tissue. They conducted a study that transplanted mesenchymal stem cell from the tibia of rats to the torn meniscus in each rat. The stem cells were taken from the bone marrow of the tibia, harvested and transplanted into the torn meniscus. The results were promising, showing that mesenchymal stem cells could in fact proliferate and contribute to the healing of menisci. The results were so promising that they concluded “we are confident that the mesenchymal stem cell transplantation will become the new clinical strategy for the treatment for meniscus tears.”

Comprehensive Prolotherapy, Meniscal Tears and Bone Marrow Prolotherapy

In the case of a torn meniscus, a dextrose Prolotherapy solution creates a natural inflammation that creates blood flow with healing factors to this site that normally has poor blood flow. In the case of a severe meniscal tear a stronger solutions, such as platelet-rich plasma (PRP) Prolotherapy or stem cell injection therapy, taking bone marrow from the patient’s tibia and injecting it directly into the torn meniscus, are used. Whatever the type of Prolotherapy – dextrose, PRP, or Bone Marrow – the result is a natural inflammation that leads to the proliferation of cells to repair and regenerate tissue.

    Hi, I am a 28 year old male. About 3 months ago I tore my medial meniscus , the tear is not small it is in the ph as an oblique tear the body and slightly in the Ah as an vertical pheripheral tear. The pain is getting better and I fill a slight click in the back portion of my knee when I squat past 90 degrees. Will this therapy help me and if so does it heal the meniscus not just reduce pain. I also take an aspirin a day. Will this have a bad effect on the repairing prosess?
    Thanks for your time

      Thanks for reaching out. We’d be happy to help you here. Meniscal tears respond very well to Prolotherapy, often we will add Platelet Rich Plasma or other cellular Prolotherapy to speed up the process too. It helps to heal the tissue, not just in the meniscus but the surrounding tissue as well. Talk to you soon! We’ve emailed you directly with more information. Take care for now.
