Effectiveness of Platelet-rich Plasma Treatment of Knee Osteoarthritis
December 6, 2023 updated by: Pablo Schierloh, Universidad Nacional de Entre Rios
Efectividad Del Plasma Rico en Plaquetas (PRP) Para la disminución Objetiva Del Dolor y la recuperación Funcional Del Miembro Inferior en Osteoartritis de Rodilla. Evaluación de Alternativas metodológicas
Osteoarthritis (OA) is a disease that affects the joints of the body, causing pain, stiffness, and reduced mobility.
To treat knee OA, a therapy called platelet-rich plasma (PRP) is used, which involves making a concentrated substance from the patient's own blood and injecting it into the joint.
It has been shown that this therapy is effective in reducing pain; however, more research is needed to optimize the preparation and identify which patients are more receptive to the treatment.
The primary objective of this study is to evaluate two modalities of PRP application and determine whether these treatments result in better pain reduction and improved functionality.
The secondary objective is to explore the association between changes in LEFS questionnaire scores and/or maximal quadriceps isometric strength and possible clinical improvement.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: PRP-1
Platelet-rich plasma, short treatment (three sessions every two weeks)
|
The PRP will be prepared using a single centrifugation process.
Approximately 30 ml of peripheral blood will be drawn and collected into a vacutainer tubes with sodium citrate anticoagulant 0.129 mol/l (3.8%).
The tubes will then be centrifuged at 900 RPM for 12 minutes at room temperature in a benchtop centrifuge.
We will separate the lower third of the plasma fraction from all tubes with a syringe and needle, taking care to avoid the leukocyte layer.
The PRP will be refrigerated at 4°C for no less than 1 hour.
We will not use any exogenous factors to stimulate the platelet activation process.
The periauricular skin surface will be disinfected with a povidone iodine solution, and an intra-articular local anesthetic with 1% lidocaine will be applied.
A 21-gauge needle will be placed at the point of application.
Finally, PRP will be injected into the joint, and the needle will be removed.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in the Western Ontario and McMaster Universities (WOMAC) Ostearthritis Index
Time Frame: Baseline, 4 weeks, 8 weeks, 12 weeks, 16 weeks, 24 weeks, 48 weeks.
|
The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire assesses the symptoms and physical disability of individuals with OA.
The WOMAC consists of multiple-choice questions, and the responses are scored from zero to four.
The final score is calculated between 0 and 96, where higher scores correspond to greater pain, stiffness, and lower functionality, indicating worsening symptoms.
|
Baseline, 4 weeks, 8 weeks, 12 weeks, 16 weeks, 24 weeks, 48 weeks.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in the the Lower Extremity Functional Scale (LEFS) Index
Time Frame: Baseline, 4 weeks, 8 weeks, 12 weeks, 16 weeks, 24 weeks, 48 weeks.
|
The Lower Extremity Functional Scale (LEFS) questionnaire is a self-administered questionnaire assessing functional status in patients with various lower limb musculoskeletal conditions, including OA.
It consists of 20 items, each scored on a 5-point scale.
The maximum possible score is 80, indicating the best functional level.
|
Baseline, 4 weeks, 8 weeks, 12 weeks, 16 weeks, 24 weeks, 48 weeks.
|
Change in Maximum Voluntary Isometric Contraction (MVIC) strength of the quadriceps
Time Frame: Baseline, 4 weeks, 8 weeks, 12 weeks, 16 weeks, 24 weeks, 48 weeks.
|
MVIC (maximum voluntary isometric contraction) strength of the quadriceps will be assessed using an instrumented load cell, which measures in kilograms.
Objective and reliable assessment of muscle strength is well-supported for monitoring disease progression and evaluating therapeutic interventions.
The test will involve asking the patient to extend the knee with maximum possible force for 3 seconds, ensuring that the hip and knee are at 90 degrees.
Three repetitions will be performed with 2-minute rests.
|
Baseline, 4 weeks, 8 weeks, 12 weeks, 16 weeks, 24 weeks, 48 weeks.
|
Centre of pressure (COP) on the plantar surface of the foot
Time Frame: Baseline, 4 weeks, 8 weeks, 12 weeks, 16 weeks, 24 weeks, 48 weeks.
|
The measurement of plantar pressure pattern and COP will be performed using a foot-X AR-1 pressure platform.
The patient will be positioned upright or anatomically on the platform for a period of time during which the application will record the pressure values.
The measurement will be bipedal (both feet on the platform), so both an integral COP of both feet and an individual COP of each foot will be obtained.
|
Baseline, 4 weeks, 8 weeks, 12 weeks, 16 weeks, 24 weeks, 48 weeks.
|
Timed Up and Go (TUG) Test
Time Frame: Baseline, 4 weeks, 8 weeks, 12 weeks, 16 weeks, 24 weeks, 48 weeks.
|
The FTSTS and TUG tests are reliable and validated clinical tools that are used as predictors of health problems or disability.
The first one consists of the time it takes to sit and stand five times in a row.
The second one is similar, but adds a walk at a certain distance.
