Comparison of the clinical results of fixed-bearing and mobile-bearing total knee arthroplasty / 中国矫形外科杂志

ABSTRACT

0.05) at preoperatively and postoperatively the total knee score,preoperatively and postoperatively pain score,preoperatively and postoperatively patient function score,and preoperatively and postoperatively Patellar score.The postoperative maximum flexion of the fixed-bearing group and the mobile-bearing group was 108??9.3? and 99.5??10.1? respectively.There was significant difference between the 2 groups for the postoperative maximum flexion (P0.05) at the femoral valgus angle,the tibial angle,the tibial slope angle,and preoperatively and postoperatively the patellar height (Install-Salvati ratio).[Conclusion]The short-term results of the fixed-bearing posterior stabilized prosthesis and the mobile-bearing prosthesis TKA were successful.There was no significance difference between the two groups for the total knee score,function score,pain score,patellar score and radiographic results.The postoperative maximum flexion in fixed-bearing group was higher than that in mobile-bearing group.
