Abstract:Abstract objective: to observe the clinical effect of polarized light combined with ultrashort wave in the treatment of senile knee arthritis.Methods: 45 patients with senile knee arthritis were randomly divided into three groups, the polarized light treatment group (group A).Ultrashort wave treatment group (group B);Polarized light combined with ultrashort wave therapy group (group C);There were 15 cases in each group.The visual analogue scale (VAS) and the improvement rate of clinical efficacy were observed in each group.Results: VAS score of group C after treatment was significantly lower than that of group A and group B, and the difference was statistically significant (P < 0.01).After treatment, the efficacy of group C was better than that of group A and group B (P < 0.05).Conclusion: the effect of polarized light combined with ultrashort wave in the treatment of senile knee arthritis is better than that of the two alone.
