PRP
Platelet-Rich Plasma
What it is
A small sample of your blood is processed to concentrate platelets in plasma. Platelets are cell fragments that release growth factors; PRP is not a stem-cell treatment. The prepared product is injected into the selected joint or tendon, using ultrasound guidance for most procedures.
Where Dr. Yang offers it
- Selected knee osteoarthritis
- Rotator cuff, lateral or medial elbow, patellar, Achilles, and plantar fascia conditions
- Other selected tendinopathies after diagnosis and appropriate rehabilitation
What to expect
Temporary soreness, stiffness, bruising, or swelling can occur. Improvement, if it occurs, is assessed over weeks to months. The number of injections depends on the diagnosis and response; one treatment may be sufficient for some patients, while a series may be discussed for others.
Important limitations and risks
PRP is not a cure and has not been proven to regrow cartilage or reliably restore a tendon. Pain flare, bleeding, bruising, infection, and injury to nearby structures are possible. Suitability depends on the diagnosis, medical history, medications, and alternatives.
