Objectives: To evaluate the effectiveness of radial pressure wave therapy (RPWT) using three different application techniques in patients with knee osteoarthritis (KOA).

Design: Double-blind randomized clinical trial. A total of 54 patients with KOA were assigned to one of three treatment groups. Exclusion criteria included rheumatoid arthritis and prior knee surgery. The control group received RPWT in the two points of greatest pain. In the experimental groups RPWT was applied at medial interarticular line (medial group) or at both interarticular lines (medial/lateral group). Pain intensity and self-reported disability were assesed at baseline and post-treatment using the Numeric Pain Rating Scale (NPRS) and the WOMAC questionnaire, respectively. This study will have a follow-up period of six months. Intra- and intergroup differences were analyzed.

Results: The NPRS score decreased significantly in the control group (from 7.22 ± 2.07 to 5.67 ± 2.72, p=0.01) and in the medial/lateral group (from 7.12 ± 1.83 to 5.65 ± 2.31, p=0.03). The WOMAC total score also showed a statistically significant improvement in the control group (from 48.11 ± 19.53 to 40.11 ± 18.31, p=0.05) and in the medial/lateral group (from 53 ± 18.53 to 39.35 ± 21.82, p=0.01). Intra- and intergroup differences in the medial group did not reach statistical significance. No treatment-related adverse events were reported.

Conclusions: The findings of this study indicate that the application of radial pressure waves to the two interarticular lines may prove to be as efficacious as the conventional technique that targets the points of greatest pain in patients with chronic KOA. The study needs to be completed to validate these preliminary results.
