PRP (Platelet-Rich Plasma) therapy is a biological treatment based on injecting a platelet concentrate obtained from the patient's own blood into the damaged area. Platelets are rich in growth factors and are thought to support the tissue healing process.

The PRP preparation process is quite simple. 15-30 ml of blood drawn from the patient is processed in a centrifuge with special tubes to obtain a platelet concentrate. This concentrate contains 3-5 times more platelets than normal blood. The prepared PRP is injected into the damaged area under ultrasound guidance. The entire process takes approximately 30-45 minutes and anesthesia is generally not required.

PRP therapy is used for early-stage osteoarthritis, tendinopathies (tendon inflammation), ligament injuries, muscle injuries, and cartilage damage. Particularly promising results have been reported for reducing pain and improving function in knee osteoarthritis. It is also widely used in treating tendon injuries in athletes.

Advantages of PRP therapy include low risk of allergy and infection since it is prepared from the patient's own blood, the procedure can be performed on an outpatient basis, and it can be repeated. Effects typically begin to appear within a few weeks with 2-3 sessions usually recommended. However, PRP may not be equally effective in every patient and should not be considered as a replacement for surgery.
