Exosome Therapy

What Are Exosome Injections?

Exosomes are nano-sized messengers naturally released by stem cells. These powerful extracellular vesicles carry vital signaling molecules—such as proteins, lipids, and genetic material—that help coordinate healing and cellular communication throughout the body.

Unlike stem cell injections, exosome therapy delivers pure regenerative signaling factors without the use of live cells, offering a cutting-edge, cell-free approach to support tissue repair, reduce inflammation, and restore cellular balance.

At Westlake Sports Medicine, exosome injections are part of a personalized regenerative care strategy, designed to enhance healing at the cellular level with precision and consistency.

Conditions That May Necessitate Exosome Injections

Exosome therapy may be recommended for a variety of orthopedic and musculoskeletal conditions, including:

  • Chronic joint pain or stiffness
  • Early-stage osteoarthritis
  • Soft tissue injuries (tendons, ligaments)
  • Post-surgical recovery support
  •  Overuse injuries from repetitive stress
  • Inflammatory musculoskeletal conditions
  • Delayed or incomplete healing from prior injuries


This therapy is often considered when conservative measures alone haven’t achieved desired results or when patients seek non-surgical regenerative alternatives.

Signs Indicating You May Need Exosome Injections

You may benefit from exosome therapy if you’re experiencing:

  • Lingering pain or swelling in joints or soft tissues
  • Limited mobility despite therapy or rest
  • Recurrent tendon or ligament strains
  • Slower-than-expected recovery from injury
  • Imaging evidence of tissue breakdown or inflammation
  • Desire to avoid corticosteroids or surgical interventions

Benefits of Exosome Injections

Exosome therapy offers several potential advantages:

  • Reduces inflammation at the cellular level
  • Promotes tissue regeneration and repair
  • Enhances cell-to-cell communication to accelerate healing
  • Minimally invasive with low risk of reaction
  • No live cells, making it safer and more consistent than traditional stem cell therapies
  • Can be combined with PRP, physical therapy, or other modalities for synergistic benefits

What Happens During the Treatment

Exosome injections are performed as a quick, in-office procedure. After identifying the area of concern, the skin is cleaned and sterilized. A concentrated exosome solution—sourced from rigorously tested, ethically derived materials—is then injected into the targeted joint, tendon, or soft tissue using a fine needle.

Ultrasound guidance may be used to ensure precision placement. The entire session usually takes 15–30 minutes, and patients typically experience minimal discomfort.

The Recovery Process After Exosome Injections

Most patients experience mild soreness or stiffness at the injection site for a day or two, but recovery is generally fast. You can resume light daily activity shortly after treatment. Strenuous exercise should be avoided for a few days, based on your personalized recovery plan.

Full results typically emerge gradually over several weeks, as the regenerative signals encourage cellular repair and tissue healing. Follow-up care may be recommended to monitor your progress.

Exosome Injections Aftercare Guidelines

To support optimal healing, follow these aftercare tips:

  • Avoid intense physical activity for 48–72 hours
  • Apply ice packs as needed to reduce any soreness
  • Stay hydrated and maintain an anti-inflammatory diet
  • Avoid NSAIDs (like ibuprofen) unless directed, as they may hinder the regenerative process
  • Follow any physical therapy recommendations provided
  • Report any unusual symptoms, such as significant swelling or pain, to your care team

Only One Component of Your comprehensive Plan

Exosome injections are a powerful tool, but they are only one part of a broader treatment plan.
At Westlake Sports Medicine, we integrate regenerative therapies with:

  • Therapeutic exercise and rehabilitation
  • Nutritional guidance for inflammation control
  • Lifestyle and biomechanical support
  • Other modalities such as PRP or hyaluronic acid injections

By combining these elements into a unified care strategy, we help you recover more
completely, avoid unnecessary procedures, and return to the active life you love.
