No differences in functional results and quality of life after single-radius or multiradius TKA
Abstract Purpose The main objective of this study was to compare the functional results and the impact on quality of life after a  single-radius or a multiradius TKA implantation .  The secondary objectives were to compare range of motion , satisfaction and the ability to perform daily life activities with both types of implant . It was hypothesized that the single-radius TKA would lead to better functional results and better quality of life than the multiradius TKA . Methods This is a prospect i ve non-r and omized study that included 250 cases of a single-radius TKA and 224 of a multiradius posterior-stabilized TKA implanted with the same surgical and rehabilitation protocol .  Results In the 1- and 5-year follow-up , we found similar knee KSS scores ( 89.7 ± 12.1 in the multiradius group and 90.3 ± 11.7 in the single-radius group ) and functional KSS scores ( 78.6 ± 21.4 in the multiradius group and 75.8 ± 20.9 in the single-radius group ) . The pain and the Physical SF-36 scores were also similar . Range of motion ( 112 ° ± 12 ° in the multiradius group and 112 ± 12 ° in the single-radius group ) , patients ’ satisfaction and the ability to perform daily life activities were also similar in both groups . Conclusion The use of a single-radius or a multiradius posterior-stabilized knee prosthesis can improve the function of the knee and the patients ’ quality of life in a similar way at the short-term and midterm follow-up . Moreover , range of motion , patient satisfaction and the ability to perform daily life activities are similar with both types of prosthesis . As both types of prosthesis can improve the function and quality of life of the patients in a similar way , the sagittal radius of the femoral component should not be considered the main factor when choosing the model of TKA.Level of evidence Therapeutic study : Prospect i ve comparative study , Level
