Knee Arthritis
Knee arthritis, also known as knee osteoarthritis (OA), is a degenerative joint disease characterized by the gradual breakdown of cartilage in the knee joint. As the protective cartilage wears away, bones may begin to rub against each other, causing pain, stiffness, swelling, and reduced mobility. It is one of the most common forms of arthritis and a leading cause of chronic disability in adults.
Prevalence
Approximately 14 million Americans have symptomatic knee osteoarthritis, with over 650,000 knee replacements performed annually in the United States.
Who It Affects
Most commonly affects adults over 50, though younger individuals may develop it following injury. Women are more likely to develop knee arthritis than men, and risk increases with obesity, prior joint injury, and repetitive stress on the knee.

Common Symptoms
Common Causes & Risk Factors
Traditional Treatment Options
Pain Medications
Over-the-counter NSAIDs (ibuprofen, naproxen) or prescription pain relievers to manage symptoms.
Limitations: Does not address underlying cartilage damage. Long-term use associated with gastrointestinal, cardiovascular, and kidney risks.
Physical Therapy
Exercises to strengthen muscles around the knee, improve flexibility, and reduce pain.
Limitations: Helpful for symptom management but cannot regenerate lost cartilage or reverse joint damage.
Corticosteroid Injections
Anti-inflammatory injections directly into the joint for temporary pain relief.
Limitations: Effects typically last only weeks to months. Research suggests repeated injections may accelerate cartilage loss.
Hyaluronic Acid Injections
Viscosupplementation to improve joint lubrication and cushioning.
Limitations: Mixed evidence on effectiveness. Does not repair cartilage damage.
Knee Replacement Surgery
Total or partial knee arthroplasty to replace damaged joint surfaces with artificial components.
Limitations: Major surgery with significant recovery time. Artificial joints have limited lifespan (15-20 years) and may require revision surgery.
Regenerative Medicine Approach
How Regenerative Therapy May Help
Regenerative medicine approaches for knee arthritis focus on potentially supporting the body's natural healing processes. Stem cell and exosome therapies are being explored for their potential to modulate inflammation and support tissue health in the joint environment.
Potential Benefits Being Studied:
- May help modulate the inflammatory response in the joint
- Contains growth factors that may support tissue health
- Minimally invasive procedure compared to surgery
- May support the joint's natural repair mechanisms
- Can be administered as an outpatient procedure
- May be considered when other conservative treatments have not provided adequate relief
Biologics Used:
Mesenchymal Stem Cells (MSCs) derived from umbilical cord tissue
Exosomes containing growth factors and signaling molecules
Frequently Asked Questions
Is regenerative therapy a cure for knee arthritis?
No. Regenerative therapies are investigational and have not been proven to cure arthritis or regenerate cartilage. They may help some patients manage symptoms and support joint health, but results vary significantly from person to person.
How is the treatment administered?
The biologics are typically injected directly into the knee joint by a licensed healthcare provider using ultrasound or fluoroscopic guidance for precise placement.
What is the recovery time?
Most patients can resume normal activities within 24-48 hours. Some temporary soreness or swelling at the injection site is common. Your provider will give you specific post-procedure instructions.
How long before I might notice any changes?
Response times vary widely. Some patients report noticing changes within weeks, while others may take several months. Some patients may not experience noticeable benefits.
Can this replace the need for knee replacement surgery?
Regenerative therapies are not a proven alternative to knee replacement. Some patients explore these options before considering surgery, but the decision should be made with your orthopedic surgeon based on your specific condition.
