IRCT20140907019073N5 IRCT 2021-07-10 Iran University of Medical Sciences Comparison of the efficacy of platelet rich plasma injection which extracted by two methods and placebo on pain, range of motion and function of patients with osteoarthritis of the knee A Comparative Study of the Efficacy of single and double Centrifuged platelet rich plasma and placebo (normal saline injection) on Pain, ROM and Physical Function of Patients with Knee Osteoarthritis: A Double Blinded Controlled Randomized Trial with a Three-Month Follow –up 2021-07-23 anticipated 45 Complete https://irct.ir/trial/52168 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: Allocation of patients in treatment groups randomly using blockade with six blocks in one of the treatment groups will be as follows. A table of random numbers will be used to assign the blocks. For this purpose, one of the blocks is selected by chance and the patients are injected according to the proposed group in the block, respectively, and then the blocks are moved forward in sequence, and this process continues until the end of sampling. Group A is single Centrifuged group, group B is double Centrifuged, group C is a placebo group (normal saline). A:SS (single spin) B:DS (double spin) C: P (placebo) -Block1: AABBCC -Block2: ABCABC -Block3: CCBBAA -Block4: CBACBA -Block5: ABCCBA -Block6: CBAABC, Blinding description: In this study, the following people will be blind of the treatment groups of patients: Patients in the study only know that they are being injected and will not know the number of centrifuges performed. Also, in this study, injectable interventions are performed under the supervision of a sports medicine specialist, who is not aware of the number of centrifuges performed and only injects the solution into the joint. - Assessor Clinician: Assessments before and after interventions in the Sports Medicine Clinic will be performed by a sports medicine resident other than the researcher who does not know the presence of patients in the groups. - Statistical Consultant and Analyzer: Analysis of research data will be performed by a statistical consultant who is not aware of patient groups. N/A Knee Osteoarthritis. Intervention 1: Intervention group 1: The Group which treated by injection of platelet-rich plasma extracted single centrifuged. Preparation of PRP solution and injection will be done in the sports medicine clinic of Hazrat Rasool Akram Hospital. Patients are asked to discontinue anticoagulants and aspirin (if any) with their doctor's permission the week before the injection. To prepare PRP, kits (Arya Mabna Tashkis Corporation, RN: 312569, Rooyagen Kit) are used which have a completely sterile pack. To prepare the injection solution, 35 cc of intravenous blood from the upper limb was taken from the patients by a 50 cc syringe in which 5 cc of anticoagulant solution had already been drawn, and with the help of an 18 G needle-shaped blood transfusion adapter without any pressure on the piston into the four Sterile tube is transferred. At the same time, about 0.5 cc of the patient's blood will be sent to the laboratory of Hazrat Rasool Akram Hospital to check the amount of blood cells. All 4 tubes are filled in balance and placed in a centrifuge and rotated at 1600 RPM for 10 minutes, then they are taken out. In the group, the upper half of the isolated plasma centrifuge will be removed from all four tubes and only the lower half of the plasma will be used for injection. About 5 cc of the PRP solution prepared for injection into the 5 cc syringe is drawn with a 14G needle tip and about 0.5 cc is separated again to be sent to the laboratory. In case of pain, the patient can take acetaminophen without codeine and is not allowed to take aspirin for 10 days. It is recommended that patients don't put weight on injected knee and doing strenuous activity for 48 hours after the injection. One of the most important ways to treat patients with osteoarthritis of the knee is to use exercise therapy. A common exercise protocol will be prescribed for patients with osteoarthritis of the knee participating in this study. Intervention 2: Intervention group 2: The Group which treated by injection of platelet-rich plasma extracted double centrifuged. Preparation of PRP solution and injection will be done in the sports medicine clinic of Hazrat Rasool Akram Hospital. Patients are asked to discontinue anticoagulants and aspirin (if any) with their doctor's permission the week before the injection. To prepare PRP, kits (Arya Mabna Tashkis Corporation, RN: 312569, Rooyagen Kit) are used which have a completely sterile pack.

At the same time, about 0.5 cc of the patient's blood will be sent to the laboratory of Hazrat Rasool Akram Hospital to check the amount of blood cells. All 4 tubes are filled in balance and placed in a centrifuge and rotated at 1600 RPM for 10 minutes, then they are taken out. In this group, the plasma separated by the first centrifuge are drawn into the tubes and poured into two other 10 cc sterile tubes inside the box containing 0.6 cc of preservative with anti-platelet aggregation solution. It is then re-inserted and centrifuged at 3500RPM for 6 minutes. Then 3 cc end of each 2 tubes after removing the upper plasma is drawn by 5 cc syringe with 14G needle head and about 0.5 cc is separated for sending to laboratory. In case of pain, the patient can take acetaminophen without codeine and is not allowed to take aspirin for 10 days. It is recommended that patients don't put weight on injected knee and doing strenuous activity for 48 hours after the injection. One of the most important ways to treat patients with osteoarthritis of the knee is to use exercise therapy. A common exercise protocol will be prescribed for patients with osteoarthritis of the knee participating in this study. Intervention 3: Control group: Therapeutic group with normal saline injection as a placebo group. In this group, 5 cc of normal saline will be injected as a placebo after blood sampling. In case of pain, the patient can take acetaminophen without codeine and is not allowed to take aspirin for 10 days. It is recommended that patients don't put weight on injected knee and doing strenuous activity for 48 hours after the injection. One of the most important ways to treat patients with osteoarthritis of the knee is to use exercise therapy.
