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.
Platelet-rich plasma (PRP) has recently emerged as an attractive biological approach to address joint degeneration. It has gained increasing attention because of the high concentration of growth factors, cytokines, and bioactive molecules stored in platelet-rich α-granules, which have been shown to participate in joint tissue homeostasis, being involved in both healing processes and immunoregulation and modulation of inflammation. Several preparation methods are available for PRP, which can give products with different compositions and characteristics.The presence of leukocytes is one of the most debated aspects of PRP efficacy, and is used as one of the main discriminators to distinguish different PRPs. Patients with OA of the hip will be included in a randomized controlled, double-blind trial, in which one group of patients will be treated with 3 infiltrations of PRP with leukocytes and one group will be treated instead with 3 infiltrations of PRP without leukocytes. A total of 230 patients will be included and will undergo infiltrative treatment after collecting informed consent for study participation. Patients will be clinically evaluated before the injection procedure and at 2-6-12 months after treatment by the medical staff.

RECRUITINGWestern Ontario and McMaster Universities Osteoarthritis Index (WOMAC)
It's a standardized and widely used questionnaire to assess the condition of patients with osteoarthritis of the knee and includes assessment of pain, stiffness, and physical function of the joints. It can be administered to the patient. It measures 5 items for pain (range 0-20), two for stiffness (range 0-8), and 17 for functional limitation (range 0-68) that mainly relate to activities of daily living (e.g., getting up from a sitting position, bending over, going up and down stairs etc.); The score is then normalized on a 0-100 scale. Higher values indicate a worse outcome
Time frame: 6 months follow-up

Visual Analogue Scale (VAS)
VAS is a visual analogue scale consisting of a range scale (10 cm length), the ends of which correspond to "no pain" and "the strongest pain imaginable".
Time frame: baseline, 2 months, 6 months and 12 months follow-up
Harris Hip Scale (HHS)
This scale was developed for the evaluation of hip surgery outcomes and is intended to assess various hip disabilities and treatment methods in an adult population. The four sections that make up the questionnaire are: pain, function, absence of deformity, and range of motion. The HHS is a measure of dysfunction, so higher is the score, better is the outcome for the individual. The maximum possible score is 100.

EQ-5D (EuroQoL) Current Health Assessment
EQ-5D is a standardized measure of health-related quality of life developed by the EuroQol Group to provide a simple generic questionnaire for use in clinical and economic evaluation and population health surveys
Time frame: baseline, 2 months, 6 months and 12 months follow-up
Patient Acceptable Symptom State (PASS)
A tool to assess patient satisfaction in consideration of their current degree of pain, function, and daily activity. Patients can express if their state of health will be satisfying, answering "yes" or "no.
Time frame: baseline, 2 months, 6 months and 12 months follow-up
