Platelet-Rich Plasma (PRP) injections are a treatment used to accelerate healing in various
areas, including the knee. Here's an overview of PRP injection for knee issues:
What is PRP?
PRP is a concentration of platelets and plasma from your own blood. Platelets are rich in
growth factors, which help in tissue repair and regeneration.
How is PRP Prepared?
- Blood Draw: A small amount of your blood is drawn.
- Centrifugation: The blood is placed in a centrifuge, which spins it at high speed to
separate the platelets and plasma from other blood components.
- Collection: The concentrated platelets and plasma are collected.
PRP Injection Procedure
- Preparation: The knee area is cleaned and prepped.
- Injection: Using ultrasound guidance, the PRP is injected into the affected area of the
knee.
- Post-Injection Care: You may need to rest the knee for a short period, avoid strenuous
activities, and follow specific aftercare instructions from your doctor.
Conditions Treated with PRP Injections
- Osteoarthritis: Helps reduce pain and improve function.
- Tendon Injuries: Assists in healing tendons around the knee.
- Ligament Injuries: Supports the repair of damaged ligaments.
- Meniscus Tears: Can promote healing of the meniscal tissue.
Benefits of PRP Injections
- Minimally Invasive: Less invasive than surgical options.
- Natural Healing: Utilizes your own blood components to promote healing.
- Reduced Pain: Can help reduce pain and inflammation.
- Improved Function: May improve knee function and mobility.
Risks and Considerations
- Pain at Injection Site: Some discomfort or pain post-injection.
- Infection: Risk of infection, though rare.
- Effectiveness: Varies by individual and condition severity.
- Cost: PRP is often not covered by insurance and can be expensive.
