How Stem Cell Therapy Is Used to Address Osteoarthritis and Joint Degeneration

Key Takeaways

• Osteoarthritis is a degenerative joint condition that leads to cartilage breakdown, inflammation, and chronic pain.
• Stem cell therapy is being explored as a regenerative approach to support joint health rather than only masking symptoms.
• Treatment focuses on reducing inflammation and supporting the joint’s repair environment.
• Knees, hips, shoulders, and other weight-bearing joints are commonly treated.
• Results vary by individual, joint condition, and severity of degeneration.

Osteoarthritis is caused by joint wear and tear as the cartilage between joints breaks down with age. Stem cells regulate the body’s natural ability to generate new tissue and may help relieve the symptoms of osteoarthritis by repairing cartilage that insulates the joints.

What Is Osteoarthritis and Why Joint Pain Gets Worse Over Time

Osteoarthritis is a degenerative joint disease where the tissues around the joint gradually deteriorate with repeated motion and begin to break down (Garrick, 2023). Soft tissues like cartilage insulate the area where the two bones meet to form a joint, providing shock absorption during physical activity. As cartilage deteriorates, patients experience pain, swelling, and mobility issues. Inflammation occurs when damaged tissues release cytokines into the bloodstream. Prolonged inactivity weakens the muscles, putting more pressure on the joints. The inability to exercise can lead to weight gain, which puts more stress on weight-bearing joints like the ankles and knees. 

There is no cure for osteoarthritis, and the disease doesn’t typically resolve itself on its own. It is more common in older adults, but it is not a regular part of aging (Centers for Disease Control and Prevention, 2024). However, the body has a limited ability to repair damaged tissues in the joints as we get older. Without healthy cartilage to insulate the joints, patients will continue to feel pain during physical activity, and symptoms often get worse over time without intervention.

Common Joints Affected by Osteoarthritis

Osteoarthritis manifests differently in patients and can affect all types of joints depending on the person’s activity levels. Common problem areas include:

• Knees
• Hips
• Shoulders
• Hands
• Ankles
• Spine 

Repeated motions, poor posture, and hard falls or heavy lifting can all damage the joints by tearing and straining the soft tissues. The knees tend to be the most frequently impacted. The meniscus insulating the knees often deteriorates with running, standing, and squatting. Reaching over and carrying heavy loads can damage the back and spine. Jobs that require patients to work with their hands can lead to pain in the hands and shoulders. 

Traditional Treatment Options for Osteoarthritis

The body loses its ability to repair damaged joint tissues as we get older. Patients are typically advised to modify their physical activity to prevent flare-ups and further deterioration. Physical therapy can help strengthen weak muscles and correct poor posture. Anti-inflammatory medications can help relieve swelling, pain medications can reduce discomfort, and corticosteroid injections can reduce pain and swelling in the joints. Patients with no or little remaining cartilage may need an artificial joint to return to a healthy lifestyle (Garrick, 2023).  

In most cases where the joints are beyond repair, conventional treatments only temporarily relieve symptoms and do not treat the cause of degeneration at its source. Medications, injections, and physical activity cannot replace the cartilage that has been lost.

What Is Stem Cell Therapy for Joint Conditions?

Stem cells represent a new approach to treating osteoarthritis. Rather than managing symptoms, stem cell therapy for arthritis aims to reduce inflammation and regenerate healthy tissues that insulate the joints, thus treating symptoms at the source. 

Stem cells reside in all tissues and regulate cellular division, which replaces damaged cells with healthy ones, by signaling repair in surrounding cells. They also contain properties that help modulate the immune system by regulating cytokine production, which leads to swelling in damaged tissues affected by osteoarthritis. 

Injecting stem cells for arthritis treatment into the affected joints can help repair damaged cartilage, tendons, ligaments, spinal discs, and meniscus. Injections are targeted to the areas experiencing degeneration. Treatments using stem cell IVs can also reduce inflammation across the body to support healing in the joints, while increasing mobility and energy levels to help patients return to an active lifestyle. 

Why Stem Cell Therapy Is Being Used for Osteoarthritis

Stem cells are essential to cartilage repair. Research shows that these tissues are slow to regenerate in adults. Mesenchymal stem cells (MSCs) are found in the fluid inside the joints, which can regenerate cartilage, but it is extremely fragile and can be destroyed with minimal amounts of pressure (Uth, 2014). Patients with osteoarthritis often experience elevated levels of inflammation that can make the disease worse. 

Osteoarthritis stem cell therapy takes stem cells from a donor or the patient’s own body and injects them into the affected joints to accelerate new tissue growth while easing inflammation. It has the potential to slow the progression of the disease in mild to moderate cases. Clinical trials involving MSCs are underway in the U.S., but adult stem cells have a limited ability to regenerate tissues, especially when they are derived from patients experiencing osteoarthritis. 

Cartilage Repair and Regeneration: What Science Suggests

Cartilage is slow to heal and regenerate in adults because older stem cells have a limited capacity to signal repair in surrounding tissues. These tissues are avascular, meaning there is no direct blood flow to the area. Nutrients in the blood flow must be diffused throughout the surrounding area to reach the soft tissues. Reduced activity and circulation issues can prevent nutrients from reaching the area, leading to degeneration (Chang et al., 2022). 

As the youngest stem cells, pluripotent stem cells from donated blastocysts have enhanced signaling capabilities that can help repair damaged joint tissues. They are able to signal repair in all tissue types, including those affecting the joints, and may lead to better outcomes than MSCs. However, treatment will only be successful if the joints are properly aligned and are supported by healthy biomechanics.

The Role of Plurisomes™ in Advanced Joint Therapy (Brief Overview)

Plurisomes™ are the exosomes of pluripotent stem cells, the proteins that help signal repair in surrounding tissues. They can extend and strengthen the signaling properties of stem cell injections for joints, helping them repair hard-to-reach niches like cartilage. Plurisomes™ may be combined with stem cells in some cases of osteoarthritis to ensure the cells reach the targeted areas that depend on nutritional diffusion rather than direct blood flow. 

What the Stem Cell Injection Process Typically Involves

Stem cell therapy for arthritis begins with a complete medical evaluation and imaging tests of the affected joints, including X-rays, an MRI, or a CT scan, depending on the patient’s condition. Stem cell joint injections are administered directly into the affected joints, such as the knees, shoulders, hands, spine, or hips. Providers track tissue regeneration, inflammation, and symptom levels as injections continue daily for several weeks. At the end of therapy, patients receive guidelines for resuming physical activity and regularly follow up with the clinic to report their progress.

Who May Be a Candidate for Stem Cell Therapy for Osteoarthritis

Patients may consider stem cell injections for joints if they are looking for alternatives to surgery. While stem cell therapy is not meant to be a replacement for surgery in severe cases of osteoarthritis, it can help delay surgery by regenerating tissues or slowing the progression of the disease. Individuals experiencing mild to moderate joint degeneration may benefit from therapy as they work toward recovering their strength, reducing discomfort, and increasing mobility.

Setting Realistic Expectations for Arthritis Treatment

Stem cell therapy represents the next frontier in the fight against osteoarthritis, but it is not a cure, and outcomes cannot be guaranteed. Many patients experience noticeable improvements within several weeks to six months, but cartilage repair happens slowly and varies depending on the patient’s lifestyle and overall health. Therapy should also be combined with physical therapy and exercise monitoring to prevent further damage.
