Platelet-rich plasma injections claim to ease inflammation and support cartilage cell growth. What can PRP achieve — and where does it fall short?

A therapy using a patient's own blood plasma is being used to treat knee injuries and early osteoarthritis. The method, known as platelet-rich plasma (PRP) therapy, involves extracting platelets from the patient's blood and injecting them into the affected joint to promote healing and reduce inflammation.

Doctors report that PRP can help regenerate cartilage cells, relieve symptoms, and may slow further joint degeneration. While the treatment is not a replacement for surgery, it is considered a low-risk, supportive option and can be applied to other joints as well. The scientific effectiveness of PRP is still under investigation, and each injection costs approximately 200 euros.
