Platelet-rich plasma (PRP)

Platelet-rich plasma (PRP) is an orthobiologic treatment: it is obtained from a sample of the patient's own blood, the platelet-rich portion is concentrated and applied to the area being treated. Platelets contain growth factors, substances involved in tissue repair. It is not surgery. It does not replace an evaluation.

What it aims for

• Stimulating the repair of cartilage, tendons, ligaments and muscle
• Modulating inflammation
• Supporting the recovery of function as part of a regenerative plan

When it may be considered

• Sports injuries of tendons, ligaments or muscle
• Joint degeneration

It can be applied in the knee, hip, shoulder, ankle, plantar fascia, elbow and wrist. Whether it is indicated, and where, is decided during the evaluation. More about knee, shoulder, hip and heel pain.

With prolotherapy

Sometimes they are combined: growth factors inside the joint and prolotherapy outside it, to strengthen the ligaments and tendons that provide stability.

How it is done

Sessions

The number of sessions depends on each patient and on how severe the condition is. It is defined during the visit, in a personalized protocol.

Before and after

There is no rule to stop medications, but before the procedure let us know which ones you take (including anti-inflammatories and blood thinners), and whether you have a bleeding disorder or allergies, so the doctor can advise case by case.

Afterward, the most important thing is not to overload the joint: too much effort can irritate the treated area and slow recovery.

• Rest for the first 24–48 hours. Avoid demanding activities and repetitive movements.
• Stay active, but in moderation: light activities such as easy walking, as tolerated.
• Avoid overloading the area: lifting weights, strength training, running, jumping or impact, going up and down stairs too much, standing or squatting for long periods, high-impact sports, and twisting or sudden movements.
• Apply ice locally for 15–20 minutes, 2–3 times a day during the first 2–3 days.
• You can take acetaminophen (paracetamol) if you need it. Anti-inflammatories are not recommended unless a doctor indicates them.
• Drink enough water during the day.
• After the first few days, gentle stretching as your doctor indicates, and, if there is no pain, a stationary bike at an easy pace, swimming, and light mobility and balance exercises.

A mild inflammation or discomfort is normal. Every body is different and recovery times vary. If fever, redness, significant warmth or swelling appear, or severe pain that gets worse as the days go by, seek medical attention right away.

What it does not promise

It does not guarantee cartilage regeneration or avoiding surgery when surgery is already indicated. Results vary with the injury, how long it has been present and each person.
