Overview
Understanding regenerative medicine / prp
A blood sample is processed to concentrate platelets in plasma. The preparation is then injected into the target area, often with image guidance. Because preparation methods and clinical uses vary, PRP is not one uniform treatment.
Some evidence supports PRP for selected tendon problems and mild-to-moderate knee osteoarthritis, while evidence for many other uses remains limited or mixed. The diagnosis, alternatives, cost, and insurance coverage should be discussed before treatment.
Useful context
When this may be discussed
- Selected chronic tendon conditions
- Selected mild-to-moderate knee osteoarthritis
- Other carefully evaluated musculoskeletal problems where evidence and goals are discussed clearly
At the clinic
What the process may involve
- 01
A review of the diagnosis, prior care, medications, and whether PRP is supported for that target
- 02
A blood draw and processing step to prepare the platelet concentrate
- 03
Injection into the selected area, sometimes with ultrasound guidance
- 04
A recovery and rehabilitation plan tailored to the treated tissue
Benefits, limits, and risks
Questions to discuss before treatment
- Pain can temporarily increase after injection.
- Infection, bleeding, nerve or tissue injury, and lack of benefit are possible.
- Effectiveness varies by condition and preparation; broad claims that PRP regenerates or cures damaged tissue are not appropriate.
