What Is Patellofemoral Pain Syndrome?
Patellofemoral Pain Syndrome occurs when the kneecap (patella) doesn’t move smoothly over the femur, causing inflammation and discomfort behind or around the kneecap. Common in athletes and active individuals, PFPS is also triggered by long periods of sitting, climbing stairs, or squatting.
Our clinic sees PFPS regularly in Los Angeles professionals, runners from Santa Monica and Pacific Palisades, and young adults from Culver City and Brentwood who are looking for alternatives to surgery or cortisone injections.

How PRP and Stem Cell Therapy Treat PFPS
Platelet-Rich Plasma (PRP) injections use your body’s concentrated growth factors to reduce inflammation and enhance soft tissue healing. PRP is especially effective for patients with early to moderate PFPS and is performed using precision ultrasound guidance for accurate delivery.
- No surgery or downtime
- Performed in-office in under 45 minutes
- Long-term pain relief with natural healing
For more advanced cases or recurring knee pain, stem cell therapy can help repair damaged tissues in the patellofemoral joint. Derived from your own adipose or bone marrow tissue, these cells support regeneration at the cellular level, often improving function and mobility over time.
Clinical research indicates that 85% of PFPS patients receiving PRP report significant improvement within 12 weeks.
Frequently Asked Questions (FAQ)
-
PFPS is caused by poor alignment, overuse, or weakness in the surrounding muscles. It’s common in runners, cyclists, and people who spend extended time sitting.
-
PFPS specifically affects the kneecap’s movement and causes pain when the patella doesn’t glide correctly. Arthritis involves cartilage degeneration; tendonitis involves tendon inflammation.
-
These therapies reduce inflammation, stimulate healing, and help correct the underlying problem. Many patients report lasting relief, especially when combined with physical therapy.
-
Most patients resume light activity within a few days. Full recovery may take several weeks depending on treatment type and severity.
-
Some need just one PRP or stem cell session, while others may benefit from a short series. Dr. Nourparvar will design your plan based on clinical exam and imaging.
-
Currently, most insurance plans do not cover PRP or stem cell therapy. However, our team offers clear pricing, payment plans, and membership discounts to make care affordable.
