What Is Plica Syndrome?
Plica Syndrome is an inflammation of the synovial fold (or “plica”) inside the knee joint. These folds are normally harmless, but trauma or repetitive use can cause them to thicken and irritate surrounding structures–especially the medial plica. Common symptoms include sharp knee pain, a popping sensation, or a catching feeling during movement.
Because Plica Syndrome is frequently misdiagnosed as a meniscus tear or general patellofemoral pain, accurate diagnosis requires a skilled specialist. Dr. Nourparvar uses real-time ultrasound imaging, biomechanical assessment, and clinical experience to differentiate plica-related pain from other orthopedic issues–ensuring you receive the right treatment the first time.
Research Papers: Advancing Evidence-Based Treatment
Dr. Nourparvar’s treatments are backed by a growing body of clinical research and his own professional contributions. He stays current on the latest regenerative breakthroughs and ensures every protocol is grounded in scientific literature and real-world outcomes.

PRP and Stem Cell Therapy for Plica Syndrome
If you’ve been told that surgery is your only option for chronic knee pain, you may be a strong candidate for regenerative treatment. We offer Platelet-Rich Plasma (PRP) and stem cell therapy to naturally reduce inflammation and stimulate joint repair for Plica Syndrome.
Platelet-Rich Plasma (PRP)
PRP is created by concentrating healing growth factors from your own blood. Injected into the inflamed plica under ultrasound guidance, it reduces irritation and promotes tissue recovery.
- 100% natural, no steroids or drugs
- Office-based procedure with no downtime
- Typically takes 30-45 minutes
- Effective in 75-85% of cases, per recent studies
Stem Cell Therapy
For more advanced cases, we may recommend adipose- or bone marrow-derived stem cells to help regenerate irritated or thickened synovial tissue.
- Especially useful for recurring or chronic inflammation
- Long-term healing at the cellular level
- Performed under strict FDA-compliant protocols
Patients from Brentwood, Mid-City, West Hollywood, and Marina del Rey often seek out our regenerative alternatives when traditional orthopedics have failed.
Frequently Asked Questions (FAQ)
-
If you experience knee pain near the kneecap, snapping or clicking when bending, or discomfort with stairs or prolonged sitting, you may have inflamed plica tissue. A physical exam and ultrasound at our clinic can confirm the diagnosis.
-
While symptoms can overlap, plica pain is usually more localized near the front of the knee and may feel like something catching or snapping. Dr. Nourparvar uses diagnostic imaging and orthopedic testing to distinguish between the two.
-
Not usually. Most patients see significant improvement with PRP or stem cell therapy, often avoiding arthroscopic surgery entirely.
-
Mild soreness is common for a day or two. Many patients report symptom improvement within 3-4 weeks, with full results in 8-12 weeks.
-
Yes. We use only autologous (your own) biologics processed in sterile, compliant conditions. No foreign substances or synthetic chemicals are used.
-
While insurance generally doesn’t cover regenerative procedures, we provide transparent pricing, flexible financing, and affordable membership plans to ensure access to high-quality care.
