What is stem cell injection?
Stem cell injections for knees. The cartilage covering the ends of the bones enables the bones to glide smoothly against one another with only slight friction. OA causes damage to the cartilage and leads to increased friction — resulting in pain, inflammation, and ultimately, a loss of mobility and function.

Stem cell therapy for knees is a minimally invasive procedure that has the potential to decrease inflammation, halt the progression of arthritic damage, repair joint cartilage, and delay or avoid knee replacement surgery.
What happens when you inject stem cells into your knee?
In other words, when adult stem cells are injected into a knee with damaged cartilage, they can act to repair damaged tissue and build new cartilage.
How are adult stem cells extracted?
Adult stem cells can be extracted by minimally invasive methods from fat tissue and bone marrow. Bone marrow stem cells have a good potential for differentiation, and the concentrated cells have numerous growth factors that aid in the cartilage formation process.
What is the impact of osteoarthritis on the knee?
The Impact of Osteoarthritis. Osteoarthritis is a chronic degenerative disorder that ultimately leads to a gradual deterioration of knee joint cartilage. Osteoarthritis may also be the result of a prior injury to the knee joint such as a fracture, tendon damage, or ligament tears.
What are adult stem cells?
Adult stem cells are incredibly versatile in a medical sense. They have a potential to reliably differentiate into cartilage, bone, fat, or soft tissue. Because of this, the injection of progenitor cells, especially mesenchymal stem cells (special stem cells from adipose tissue or bone marrow), have been shown to be a better strategy to repair degenerative cartilage than implantation of differentiated cells –– such as articular cartilage.
Why are fat derived stem cells better than bone marrow?
Not all research is favorable to stem cell therapy due to a wide variation in techniques and cell choice and from discrepancies in treatment methods.
Why is cartilage important in the knee?
The major function of joint cartilage is to allow for smooth gliding of joint surfaces and to protect the surrounding bone from stress. This sort of movement is key for individuals who participate in sports such as skiing. In a wider context, though, knee cartilage damage can prevent people from running, exercising, or just moving as freely as they’d like. Articular cartilage allows the knee to absorb shock and loads up to 20 times the body weight.
What Conditions Do Stem Cell Therapies for Knees Treat?
The main conditions treated by stem cell injections include knee osteoarthritis, cartilage degeneration, and various acute conditions, such as a torn ACL, MCL, or meniscus. Stem cell therapy may speed healing times in the latter, while it can actually rebuild tissue in degenerative conditions such as the former.

How Does Stem Cell Therapy Work?
Although it may sound like an intensive procedure, stem cell therapy is relatively straightforward and usually minimally invasive. These days, physicians have many rich sources of adult stem cells, which they can harvest right from the patient’s own body. This obviates the need for embryonic stem cells, and thereby the need for moral arguments of yore.

In order for patients to participate in the study, they had to have two damaged knees. The researchers then gave patients a stem cell injection in one knee and a saline injection in the other, without clarifying to the patients which treatment was which.
Why do stem cells need growth factors?
That’s why stem cell clinics may also introduce growth factors to the area. These are hormones that tell the body to deliver blood, oxygen, and nutrients to the area , helping the stem cells thrive and the body repair itself . Physicians may extract these growth factors from blood in the form of platelet-rich plasma (PRP).
What is the role of stem cells in knee surgery?
The primary role of adult stem cells is to maintain healthy tissue and initiate the healing of damaged tissue by replenishing dying or damaged cells. When injected into your knee, stem cells find the damaged cartilage and have the potential to initiate its repair or regeneration.

How to determine if you are a candidate for stem cell surgery?
The doctor should evaluate whether you are a candidate for a stem cell procedure by discussing the circumstances of your injury, examining the painful knee, and reviewing the appropriate imaging during your consultation. Once the doctor has a thorough understanding of your injury, they can then make treatment recommendations specific to your case.
What is a live x-ray for knee injection?
With the use of live x-ray guidance, the cells and growth factors are injected into the affected knee joint under sterile conditions. Dr. Brandt‘s extensive experience with knee injections, along with the aid of the appropriate image guidance, ensures the cells are reaching their targeted area so you have the best chance for improvement.

Cell types like mesenchymal stem cells (MSCs) can exert powerful therapeutics effects when they are administered to a site of injury, most commonly reducing inflammation and scarring (fibrosis). The result is, your knee pain goes away.
What Are Stem Cells?
Stem cells differ, because they can become any other cell in the body. They can also replicate themselves to create new stem cells. As a result, they can help fix problem areas. Stem cell treatment is a form of self-healing.

How many clinical trials use MSCs?
There are now 1,186 clinical trials listed at ClinicalTrials.gov that use MSCs in the treatment protocol. Other types of stem cells also exist, such as hematopoietic stem cells, neural stem cells, and induced pluripotent stem cells, but these cell types tend to be used for other applications.
How do stem cells heal knees?
However, stem cells have the potential to fix these damaged areas. One way stem cells heal knee pain is by differentiating into new, healthy cells. The result is healthy, new tissue. A second way is my indirect (paracrine) effects, such as reducing inflammation and scarring at the site of injury.
What happens when you fall on your knee?
When a person falls and injures his or her knee, several bodily mechanisms are engaged to heal the immediate injury. However, there are often side effects too, such as inflammation and scarring (fibrosis). As a result, you may feel knee pain. You may also develop chronic knee pain or mobility issues.
How is cartilage repaired in knees?
Existing cell therapy to repair knee cartilage generally involves surgically debriding the cartilage defect and then taking a biopsy of healthy cartilage from the patient. The biopsy is cultured in an outside laboratory, and the cultured cells are implanted weeks later. "We wanted to improve this technique because during the waiting period, the patient's life is on hold, costs increase and the logistics can be complex," Dr. Saris says.
What is a RECLAIM procedure?
RECLAIM is used to repair symptomatic cartilage defects, usually resulting from trauma or an athletic injury. The procedure might be suitable for nonarthritic patients ages 18 to 50 who have fresh cartilage defects.
What is the process of resected tissue?
The resected tissue is processed and, using a rapid isolation protocol, digested into chondrons. Mixing the chondrons with allogeneic stem cells from the stem cell bank provides sufficient cells to immediately re-inject into the patient.
