ObjectiveTo observe the clinical effect of combined glucosamine hydrochloride and antiosteoporosis drugs in the treatment of senile knee osteoarthritis. MethodsA total of 120 patients with osteoarthritis of the knee treated from January 2014 to December 2015 were randomly divided into observation group and control group with 60 cases in each. The observation group received not only oral glucosamine hydrochloride, but calcium D3, alfacalcidol, and sodium phosphate for anti-osteoporosis treatment, while the control group was only given oral glucosamine hydrochloride. Lequesne score, curative effect and adverse drug reactions were compared between the two groups 2, 4, and 6 weeks after the beginning of treatment. ResultsWithin two weeks of treatment, there was no significant difference between the two groups in the effective rate (P ＞ 0.05) . But four and six weeks after treatment, the efficiency in the observation group was significantly higher than that in the control group (χ2=6.806, P ＜ 0.01; χ2=24.762, P ＜ 0.01) . Four and six weeks after treatment, Lequesne score of the observation group was significantly lower than that of the control group (t=2.199, P ＜ 0.05; t=4.748, P ＜ 0.001) . There was no significant difference in terms of adverse reactions between the two groups before and after treatment (χ2=0.617, P ＞ 0.05) . ConclusionCompared with single hydrochloric amino glucose treatment, glucosamine hydrochloride combined with anti-osteoporosis treatment for senile knee osteoarthritis has better treatment effect without increase in adverse drug reactions, and it is worth of clinical application.
