Abstract：Objective: To investigate the effects of nimesulide combined with loxofen sodium on TIMP-1, MMP-3 and bone metabolism in patients with knee osteoarthritis. Methods: From January 2019 to September 2021, 92 patients with knee osteoarthritis were included in this study as the observation subjects and divided into control group (n=46) and combined group (n=46) according to the randomized-control principle. The control group was given loxofen sodium. The combined group was given nimesulide combined with loxofen sodium both group for 4 weeks as a course of treatment. All patients completed the treatment and were followed up. The efficacy of the two groups was evaluated at the end of the 4-week course of treatment. The serum levels of matrix metalloproteinase 3 (MMP-3), matrix metalloproteinase inhibitor 1 (TIMP-1), osteocalcin (BGP) and osteoprotegerin (OPG) were measured before and after treatment, and the adverse reactions were recorded. Results: The total effective rate of the control group was 82.61% (38/46), which was lower than that of observation group 95.65% (44/46), and the difference was statistically significant (P<0.05). Compared with before treatment, serum MMP-3 decreased and serum TIMP-1 increased in the two groups after 4 weeks of treatment, the difference of serum MMP-3 and TIMP-1 before and after treatment was statistically significant (P<0.05). Compared with before treatment,the serum BGP and OPG levels increased in both groups after 4 weeks of treatment. The difference of serum BGP and OPG levels before and after treatment between the two groups was statistically significant (P<0.05).There was no statistical significance in the adverse reaction rate between the two groups (P>0.05). Conclusion: Nimesulide combined with loxofen sodium can improve the treatment efficacy among knee osteoarthritis patients, improve bone metabolism and matrix metalloprotein level with high safety.
