Intraarticular Injections of Platelet-rich Plasma in Pain's Treatment of the Osteoarthritic Knee

May 15, 2015 updated by: Fundación Pública Andaluza para la Investigación de Málaga en Biomedicina y Salud

Platelet-rich plasma (PRP), due to its high content of cytokines, bioactive proteins and platelet growth factors, may contribute to diminish the pain of arthritic knee. It was also recently recognized a regenerative cell potential improving the concentration of hyaluronic acid and stabilizing angiogenesis in arthritic knees

This study therefore seeks to assess the analgesic power of PRP in osteoarthritic knees intraarticularly infiltrated, and which patients would benefit most from treatment, eliminating false expectations in the rest.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is the first clinical trial developed following the report of the Spanish Competent Authority on May 23, 2013, considering the PRP as a medicinal product for human use and establishing minimum guarantees required of the product and the process of manufacturing. It has been conducted from the perspective of both the trauma and the specialized treatment of chronic pain anesthesiologist, and manufacturing the PRP on the premises of a Regional Centre for Transfusions, all belonging to the Public Health System and therefore without commercial interests.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Changes from baseline Visual Analogue Scale (VAS) value
Time Frame: Evaluation will be conducted at 28 days,3 months and 6 months after first infiltration
The main objective of this study is to determine the clinical value of intraarticular injections of platelet-rich plasma (PRP) in the reduction of perceived pain in patients with osteoarthritic knees
Evaluation will be conducted at 28 days,3 months and 6 months after first infiltration

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Changes from baseline Knee and Osteoarthritis Outcome System (KOOS) scale value
Time Frame: Evaluation will be conducted at 28 days,3 months and 6 months after first infiltration
KOOS is an instrument to assess the patient's opinion about their knee and associated problems. It includes 5 subscales which measure respectively the pain, symptoms, activities of daily living, sporting activity and quality of life
Evaluation will be conducted at 28 days,3 months and 6 months after first infiltration
Effects on quality of life
Time Frame: Evaluation will be conducted at 28 days,3 months and 6 months after first infiltration
EUROQOL (European Quality of Life) for the evaluation of function and quality of life
Evaluation will be conducted at 28 days,3 months and 6 months after first infiltration
All reported adverse events
Time Frame: Evaluation will be conducted at 28 days,3 months and 6 months after first infiltration
Evaluation will be conducted at 28 days,3 months and 6 months after first infiltration
