Abstract:

Objective

To evaluate the effect of zoledronic acid on bone mineral density after total hip arthroplasty in the patients with osteoporosis.

Methods

Main databases from the inception of each database up to 10 November 2019 were electronically searched. Randomized clinical trials (RCTs) of zoledronic acid on bone mineral density after total hip arthroplasty in patients with osteoporosis were included. The Cochrane risk of bias tool was used to assess the risk of bias. The quality of included studies was assessed using the Jadad rating scale. The Cochrane Collaboration’s RevMan5.3 software was used for meta-analysis.

Results

Five studies were included and made a meta-analysis. The meta-analysis results showed that three months after operation, the bone mineral density of Gruen 2 area [mean difference (MD)=0.11, 95% confidence interval (CI) (0.01, 0.21), Z=2.21, P=0.03], Gruen 3 area [MD=0.11, 95% CI (0.01, 0.21), Z=2.24, P=0.03], and Gruen 6 area [MD=0.12, 95% CI (0.04, 0.21), Z=2.76, P=0.006] in the treatment group were significantly higher than those in the control group; six months after operation, the bone mineral density of Gruen 1 area [MD=0.05, 95% CI(0.01, 0.09), Z=2.20, P=0.03], Gruen 2 area [MD=0.08, 95% CI(0.03, 0.14), Z=3.03, P=0.002], Gruen 3 area [MD=0.05, 95% CI (0.00, 0.10), Z=2.10, P=0.04], Gruen 4 area [MD=0.10, 95% CI(0.04, 0.15), Z=3.46, P=0.0005] and Gruen 5 area [MD=0.08, 95% CI (0.03, 0.14), Z=2.87, P=0.004] were significantly higher than those in the control group; 12 months after operation, the bone mineral density of Gruen 1 area [MD=0.09, 95% CI (0.05, 0.14), Z=4.22, P<0.0001], Gruen 2 area [MD=0.11, 95% CI(0.05, 0.16), Z=3.91, P<0.0001], Gruen 3 area [MD=0.08, 95% CI (0.03, 0.13), Z=3.42, P=0.0006], Gruen 4 area [MD=0.15, 95% CI(0.09, 0.20), Z =5.01, P<0.00001] and Gruen 5 area [MD=0.10, 95% CI (0.05, 0.16), Z=3.77, P=0.0002] were significantly higher than those in the control group. No significant adverse reactions occurred in the studies included.

Conclusion

Zoledronic acid can effectively delay the decrease of bone mineral density after total hip arthroplasty, increase the biological stability of the prosthesis, and the clinical application is safe, yet more high quality, multi-center strictly designed RCTs are needed to further verify.
