Overview

Brief Summary

To compare changes in functionality and pain level using questionnaires EVA, Lequesne and WOMAC in patients treated with 4 doses of 8 ml of autologous Platelet Rich Plasma every 15 days applied through intra-articular infiltration and patients treated with an intra-articular infiltration of 1 dose of SYNVISC-ONE ® 6 ml pre-filled syringe, placed according to standard protocol, in patients with OA grade II-IV.

Detailed Description

28 participants with grade II-IV knee OA who met all the inclusion criteria and none of the exclusion criteria were recruited and selected. They were randomized into two groups, one received 4 doses of PRP and the other conventional hyalurinic acid treatment. Each patient underwent an evaluation of their baseline condition and physical examination of the affected knee by applying the functional and pain level questionnaires: WOMAC, VAS and LEQUESNE, after which each of the treatments was applied, respectively. The control group received 1 dose of SYNVISC-ONE, placed according to the standard intra-articular infiltration protocol, and group 2 received 4 intra-articular infiltrations of activated autologous PRP placed every 15 days. The patients were assessed at 3, 6 and 12 months by physical examination and the same surveys were applied to determine the progress and efficacy of the treatments using the same surveys. Finally, a statistical analysis was performed to compare the results between the two treatments.

Outcomes

Primary Outcomes

Changes in pain levels and functionality

Time Frame: Baseline, 3 months, 6 months and 12 months.

Eva scale for the intensity of pain associated with activities of daily living and if sports activities are practiced. Lequesne index for knee osteoarthritis and physical function, pain and stiffness measured by Womac index.Each of the 3 questionnaires was evaluated at four different times: baseline, 3 months, 6 months and 12 months after treatment.
