Abstract

Abstract:

Objective

To compare single radius(SR) and multi radius(MR) femoral posterior stabilized prostheses in total knee arthroplasty(TKA).

Methods

The articles about TKA treated by SR and MR were searched in PubMed, Web of Science, the Cochrane Central Register of Controlled Trials (the Cochrane Central Register) and Excerpta Medica Database (Embase). The databases from a randomized controlled trials using SR and MR femoral posterior stabilized prostheses in firstly TKA were selected. The meta-analysis and heterogeneity test were performed with RevMan 5.3 software.

Results

Seven randomized controlled trials (RCTs) reporting 667 patients underwent total knee replacements were included in current study. The outcomes of this meta-analysis indicated that there were no significant statistical difference in Knee Society scores of functions, the range of motion, the flexion, the min flexion in stance phase and the complications between SR and MR TKA(P>0.05). The Knee Society scores of knee and max flexion in stance phase of SR were better than MR(I²=1%, Z=2.03, P<0.05).

Conclusion

No significant clinical difference is found between SR and MR posterior stabilized prostheses in TKA, but the Knee Society scores of knee and the max flexion in stance phase of SR are better than MR.
