PRP, Stem Cell, and Exosomes for Meniscus Tears in Los Angeles

What is a meniscus tear? Imagine your knee as a hinge. The bones that meet at your knee are cushioned by a piece of cartilage called the meniscus. It’s like a shock absorber, helping to distribute pressure and prevent the bones from rubbing together. When the meniscus is injured, it can tear. This often happens due to sudden twisting or pivoting movements, especially when the knee is carrying weight. Think of it like a piece of paper tearing when you twist it too hard. 

A meniscus tear can cause a variety of symptoms. This can include pain which is often felt on the side of the knee, and swelling making the knee puffy. Symptoms can also include locking, making the knee feel stuck or unable to fully straighten, and a popping or clicking noise when the knee is moved.

Stem cells, platelet-rich plasma (PRP), and exosomes are three promising therapies being explored for the treatment of meniscus tears. These treatments offer a potential alternative to traditional surgical approaches and may lead to improved outcomes for patients. 

Stem cells are undifferentiated cells that have the potential to develop into various cell types, including cartilage. When injected into the injured area, stem cells can differentiate into cartilage cells and promote tissue regeneration. PRP is a concentrated solution of platelets derived from your own blood. Platelets contain growth factors that can stimulate tissue healing and regeneration. PRP can help reduce inflammation, promote cartilage formation, and improve overall knee function. Exosomes are tiny vesicles released by cells that contain a variety of bioactive molecules. Exosomes can stimulate cell growth, reduce inflammation, and promote tissue repair. Exosomes may be particularly effective in promoting cartilage regeneration and reducing pain. Combining stem cells, PRP, and exosomes may lead to enhanced tissue repair and improved outcomes. The specific combination of therapies can be tailored to the individual patient’s needs. 

Clinical studies are ongoing to evaluate the effectiveness of these combined therapies for meniscus tears. While the results are promising, more research is needed to fully understand the benefits and risks. If interested, more thorough information has been attached below. 

If you’re considering stem cell, PRP, or exosome therapy for a meniscus tear, it’s important to discuss the potential benefits and risks with a qualified healthcare provider. They can help you determine if these treatments are suitable for your individual needs. Wondering where you can find a provider with the experience and knowledge to assist you with your treatment?

Summary of clinical studies using stem cell injections.

Author/Year Study type/Patient number Source/Cell Number Method of Delivery Outcome/Follow Up Results
Vangsness et al. [108]/2014 Randomized control trial/55 Allogeneic MSCs derived from BMAC/A:50 × 106 B:150 × 106 Percutaneous knee injection MRI, VAS, Lysholm knee score/2 years Significant improvement in scores at 3 months. 12-month MRI at 12 months: significant increase in meniscal volume in MSC groups compared to control
Pak et al. [109]/2014 Case control/1 Abdominal liposuction/Not reported Percutaneous knee injection VAS, Functional rating index, ROM, MRI/18 months At 3 months MRI showed no evidence of meniscal tear, Symptoms improved and asymptomatic at 18 months
Centeno CJ et al. [110]/2008 Case control/1 Iliac crest BMAC/45.6 × 106 Percutaneous knee injection VAS, Functional rating index, MRI/3 months Increased meniscus volume on MRI. Decreased VAS Score from 3.33 to 0.13
Onoi et al. [111]/2019 Case report/2 Liposuction from thigh/5.5 × 106 Percutaneous knee injection MRI KOOS Arthroscopy/6 months Both patients reported better scores at 6 months follow up. 2nd look arthroscopy showed meniscal tear healing
Sekiya et al. [112]/2019 Case series/5 Arthroscopically harvested Synovial Tissue/32–70 × 106 Arthroscopic transplantation of autologous synovial MSC suspension to sutured meniscal lesion Lysholm knee score KOOS NRS 3D MRI/24 months Significant improvement of Lysholm score by 1 year. Other scores significantly increased by 2 years 3D MRI: Tears were indistinguishable
