Abstract:
[Objective]To evaluate the role of mobile bearing knee prosthesis in TKA and the clinical results.[Method]A total of 301 TKAs by using mobile bearing knee prosthesis were gotten average 48.7 months follow-up.HSS knee scores and X-ray films were to used to evaluate the results.[Result]The mean HSS score improved from 51.3 before operation to 91.3 after operation.The ROM improved from extension/flexion(-9.5?/64.3?)before operation to extension/flexion(0?/97.5?)after operation.The maximum varus/valgus(25?/15?)before operation were improved to the mean valgus 5.3?.Two cases of septic loosening and 2 cases of femoral fracture were found.[Conclusion]The CR type mobile bearing knee prosthesis not only had advantages in kinematics and wear experiments,but also had achived good clinical result.
