April 23, 2021 updated by: Azienda Ospedaliero-Universitaria Consorziale Policlinico di Bari

Clinical Results Of Platelet Rich Plasma (PRP) Injections For Knee Osteoarthritis (KOA), Our Experience At Midterm Follow Up

It was conducted a prospective study with a series of 153 patients treated with PRP injections in patient affected by knee osteoarthritis. One independent observer performed clinical and functional evaluations at T0 (recruitment), T1 (one month after the injection), T2 (three months after the last injection) and T3 (six months after the last injection).

The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), the Knee Score Society (KSS) score and the Visual Analogue Scale (VAS) were evaluated and recorded for each patient at each follow up.
