Brief Summary
Knee osteoarthritis (KOA) is a disease characterized by cartilage degeneration, synovium inflammation, bone remodeling, osteophyte formation, inflammations and loss of articular function. Interest on biological therapies has increased due to the recent update on KOA and its natural history. Viscosupplementation with hyaluronic acid aims to restore rheological properties of synovial fluid. Platelet rich plasma (PRP) is an autologous blood product which contains an elevated platelet concentration above the one found in blood. The goal of this study is to compare the clinical results of intra articular infiltration of hyaluronic and platelet rich plasma in the treatment of KOA, and to establish a protocol for PRP obtaining and prepare. Patients form the OA treating program will be selected and randomized into three groups (treatment with hyaluronic acid or onte of the two PRP protocols, PRP A and PRP B). Evaluation will include: subjective functional evaluation, clinical evaluation, radiological evaluation and radiological evaluation, which will be performed before treatment and 3 weeks, 3 months, 6 months and 1 year after treatment. Evaluation of PRP composition will be performed using ELISA/LUMINEX. Key words: Knee, osteoarthritis, platelet rich plasma, viscosupplementation.

- Masking Details
- Patients will be randomized in block by simple drawing of opaque envelopes before application, in 3 experimental groups. During infiltration, patients will be sitting on the stretcher in a comfortable position, with knees flexed and blindfolded (blinding as to the treatment performed). Patients will be evaluated by an observer independent of the one who applied the selected treatment.
