Use of Leukocyte-Rich PRP or Leukocyte-Free PRP in the Treatment of Hip Osteoarthritis. Double-blind Controlled Randomized Clinical Trial

Sponsor

Istituto Ortopedico Rizzoli

Enrollment

230 participants

Start Date

Oct 5, 2022

Study Type

INTERVENTIONAL

Conditions

hip osteoarthritis

Summary

The aim of the study is to compare the efficacy up to 12 months of two different types of PRP (PRP with leukocytes vs PRP depleted of leukocytes) in the echo-guided infiltrative treatment of hip OA by including 230 patients in the study and evaluating them through subjective (using the WOMAC score as the primary outcome) and objective clinical scores.
