ObjectiveTo investigate the clinical effect of combined air pressure wave and oral glucosamine in the treatment of knee osteoarthritis. MethodsWe chose 200 patients with knee osteoarthritis treated in the Department of Rehabilitation between April 2013 and March 2015 as our research subjects. The patients were randomly divided into observation group and control group with 100 in each. The control group accepted conventional physical therapy, while the observation group underwent normal physical therapy in combination with air pressure wave and oral glucosamine treatment. We compared the two groups in terms of curative effects. ResultsThe total effective rate was not significantly different between the two groups (P＞0.05) , but in terms of efficiency rate, the observation group (85.0%) was significantly superior to the control group (73.0%) (P ＜ 0.05) . ConclusionCombined air pressure wave and oral glucosamine treatment for knee osteoarthritis is high efficient, which is worthy of being popularized.
