OBJECTIVES: This study seeks to demonstrate the influence of pharmacological substances from the SYSADOA group on the progression of osteoarthritis in the human knee. The quantification methods were direct measurement of the rheological properties of the knee joints in vivo and standard WOMAC index questionnaires. MATERIALS AND METHODS: The drugs were administered orally to 34 probands with second degree gonarthrosis for 13 weeks. The untreated control group consisted of 10 probands. The rheological properties of the joints were determined by a biorheometer, and subjective assessment of the knees by patients (WOMAC) before and after medication, and for a further 13 weeks. Changes in the calculated parameters over time were compared. RESULTS: During the audited perioda slight deterioration in all of the parameters was observed in the untreated group. The treated group, however, improved in all the parameters and some indicators showed statistically significant differences. The positive effects of the SYSADOA persisted for 3 months after the end of treatments. Partial correlation was found between the results of the WOMAC questionnaire and the rheological measurements. CONCLUSIONS: This study shows the positive effects of the preparation on arthritic changes in the knee joint, but due to the large variance of the collected data, this conclusion is on the borderline of statistical significance. The method of measuring the rheological properties of the joints is suitable for evaluating the progression of OA.
