Injection of platelet-rich plasma prepared from the patient's own blood into painful tendon and joint areas. In some cases, it may support healing.
Indication
- Chronic tendon attachment-site pain such as tennis elbow (lateral epicondylitis)
- Achilles and patellar tendon problems (tendinopathy)
- Resistant plantar fasciitis (heel pain)
- Adjunctive therapy in early-to-moderate stage knee osteoarthritis
- Adjunctive option in selected patients with certain cartilage injuries
Preparation
- Anti-inflammatory pain relievers (NSAIDs) are stopped 7-10 days before the procedure with physician approval
- Adequate fluid intake on the day of the procedure
- Avoidance of excessive fatigue and heavy exercise
- Inform the physician if blood thinners are being used
How it's performed
- A small amount of blood is drawn from the patient via a vein
- The collected blood is separated in a centrifuge using special tubes
- The platelet-rich plasma fraction is isolated
- The injection site is sterilized; local anesthesia is applied if needed
- Injection is generally performed into the target tendon or joint under ultrasound guidance
- After the procedure, the area may be cooled briefly with a cold pack
Post-procedure
- Increased pain and swelling may occur in the area during the first 1-2 days
- Heavy sports and strenuous loading are avoided for the first 2 weeks
- Gradual exercise and physiotherapy program according to physician advice
- Effects are usually evaluated within 4-6 weeks; some protocols may require 1-3 injections
- The durability of results varies according to the individual and the stage of the disease
Risks
- Temporary pain and swelling at the injection site
- Bleeding or hematoma
- Rarely, infection
- Lack of expected benefit (response varies by individual)
- Skin discoloration or tenderness on the surface
FAQ
Is PRP effective in every tendon and joint pain?
No. Scientific evidence suggests it may be supportive in certain tendon disorders and selected cases of knee osteoarthritis. Its effectiveness varies by individual, location, and stage of the disease; it does not replace standard treatment in any case.
How many injections are needed?
Depending on the clinical picture, a single session may be sufficient, or 2-3 sessions at 4-6 week intervals may be recommended. The decision is made by the physician based on examination and imaging results.
When can I return to sports after PRP?
Light activity is generally possible after 24-48 hours; however, in conditions where tendon healing is needed, waiting 2-4 weeks for strenuous sports is generally recommended.
Does PRP replace surgery?
No. In severe structural damage, advanced osteoarthritis, or full tears, PRP does not replace surgery. Your doctor will evaluate the appropriate option for you.
