About this study
Official title: Use of Fresh Platelet-rich Plasma With Concentrated Leukocytes or Fresh Platelet-rich Plasma Without Concentrated Leukocytes for Treating Knee Cartilage Degeneration: a Randomized Controlled Trial
The aim of the study is to compare the triple infiltration of Fresh Platelet Rich Plasma with concentrated Leukocytes against triple infiltration of Fresh Platelet Rich Plasma Without Concentrated Leukocytes in the treatment of Knee Cartilage Degeneration in a Double Blind Randomized Controlled Trial
Read the detailed description
Platelet Rich Plasma has a consolidated use in the field of orthopedic surgery to reduce inflammation, promoting bone regeneration and healing of surgical wounds.
Some clinical studies demonstrated the utility of the intra-articular infiltration of Platelet Rich Plasma in the treatment of knee articular cartilage lesions, becoming a common conservative strategies in the management of these diseases.
Actually, there are some different kinds of PRP formulations, in particular, the scientific debate is focusing on the role of Leukocytes and if it is better using fresh or frozen PRP.
At the moment don't exist randomized controlled clinical studies comparing fresh PRP rich in Leukocyte against PRP poor in Leukocyte in the treatment of knee cartilage lesions.
The study has two groups of patients, the first will undergo to three infiltrations of Fresh Platelet Rich Plasma With Concentrated Leukocytes and the second will undergo to three infiltrations of Fresh Platelet Rich Plasma Without Concentrated Leukocytes, each infiltrations will be done weekly.

What is being measured
The primary outcome is the main question the study is designed to answer.
IKDC-subjective score (International Knee Documentation Committee)
It is a specific subjective rating scale for te knee. Iti s one of the most reliable tools for assessing knee diseases. The survey examines three categories: symptoms, sport activity, knee function.
Measured: 12 month
Secondary outcomes (4)
KOOS score (Knee Injury and Osteoarthritis Outcome Score)
KOOS consists of 5 subscales; Pain, other Symptoms, Function in daily living (ADL), Function in sport and recreation (Sport/Rec) and knee related Quality of life (QOL). The previous week is the time period considered when answering the questions. Standardized answer options are given (5 Likert boxes) and each question is assigned a score from 0 to 4. A normalized score (100 indicating no symptoms and 0 indicating extreme symptoms) is calculated for each subscale
Measured: baseline, 2, 6, 12 and 24 months
EQ-VAS (EuroQol-visual analogue scales)
It is a rating scale for assessing the health state of the patient. The scale ranging from 0 (the worst health state) to 100 (the best health state)
Measured: baseline, 2, 6, 12, 24 months
EQ-5D (EuroQoL) Current Health Assessment
It is a reliable tools for assessing quality of life of the patient
Measured: baseline, 2, 6, 12, 24 months
Tegner Activity Level Scale
Survey useful for assessing sport activity of the patient. The Tegner activity scale is a one-item score that graded activity based on work and sports activities on a scale of 0 to 10. Zero represents disability because of knee problems and 10 represents national or international level soccer.
Measured: baseline, 2, 6, 12, 24 months

Questions about this trial
What is this clinical trial studying?
A study testing Fresh Platelet Rich Plasma with leukocyte and Fresh Platelet Rich Plasma without leukocyte in people with Osteoarthritis, Knee, run by Istituto Ortopedico Rizzoli at 1 site in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
IKDC-subjective score (International Knee Documentation Committee) (time frame: 12 month). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04187183, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Jan 2025; AzTrials last refreshed its copy on 7 Nov 2026.
