Platelet Growth Factors (PRP)

Platelet growth factors (PGF), also known as platelet-rich plasma (PRP), are bioactive proteins and molecules present in blood platelets. Platelets are blood cells that play a key role in blood clotting, but also contain growth factors that have regenerative and healing properties.

PRP is obtained by drawing blood from the patient and then processing it to concentrate the platelets and growth factors. Once obtained, the PRP is injected into the affected area, where the released growth factors promote tissue repair and regeneration.

In the case of osteoarthritis, PRP is used in selected patients as an alternative therapy to relieve symptoms and improve joint function. The growth factors present in PRP can stimulate cartilage formation, reduce inflammation and promote regeneration of damaged tissues in joints affected by osteoarthritis. This can lead to decreased pain, improved joint mobility and a slowing of disease progression in some patients.

In the case of tendinopathies, PRP is also used in selected patients to promote healing of injured tendons. The growth factors present in PRP can stimulate tendon cell proliferation, improve vascularization of the affected area and stimulate collagen synthesis. This can aid in tendon healing, reduce pain and improve tendon function and strength. Common tendinopathies in which PRP has been used include patellar tendinitis, shoulder (rotator cuff) tendinitis, Achilles tendinitis and tennis elbow tendinopathy.

It is important to keep in mind that although PRP has shown potential benefits in the treatment of osteoarthritis and tendinopathies, its efficacy may vary depending on the patient and the severity of the injury. In addition, research on the use of PRP in these conditions is still ongoing, and further studies are required to determine its long-term effectiveness and establish more precise treatment guidelines.
