Platelet-rich fibrin (PRF)
"The Intervention Group consists of the intra-articular application of PRF in the knee. The applications will be performed by the same doctor. The patients will be blinded so that they do not know to which group each individual belongs. A total of 3 applications of PRF will be conducted, with intervals of 14 to 28 days between them.~10ml of PRF will be applied intra-articularly, on an outpatient basis, with patients being instructed to follow the same protocol for physiotherapy and rehabilitation. There will be no restrictions on load or range of motion in the knee being treated."
Corticosteroid
"The procedures will be performed by the same doctor. The patients will be blinded so that they do not know to which group each individual belongs. In this group, 40ml of peripheral blood will also be collected and placed for centrifugation. During the preparation for the application, a nurse (who will not participate in the study) will have a list of the randomization and will prepare the material in an opaque syringe (blinding both the applicator and the patient).~In this group of patients, a solution of 10ml containing 40mg of Triamcinolone will be administered in the first application and 10ml of saline in the second and third applications, with intervals of 14 to 28 days between the applications. The applications will be performed on an outpatient basis, with patients being advised to follow the same protocol for physiotherapy and rehabilitation. There will be no restrictions on load or range of motion in the knee being treated."
