Abstract
Background:Mobile bearing knee arthroplasty is an alternative to a fixed bearing knee arthroplasty, we present the results of a retrospective study of a fully congruent, multi-directional mobile bearing knee with a tibial post: the Rotaglide Total Knee System.
Methods: Patients were clinically and radiologically assessed at dedicated follow up clinics. The Hospital for Special Surgery (HSS) and Knee Society Score (KSS) systems were used to describe the clinical and radiological findings. The results were analysed by an independent statistician.
Results: The study group included 88 knees. The Prosthesis had a survival rate of 93,5 % at nine years. It is associated with good rates of patient satisfaction and high scores on the HSS and the KSS System. No knees were revised for aseptic loosening.
Conclusions: This, fully congruent, multidirectional mobile bearing knee replacement has survival equivalent to other prosthesis. It is a safe, reliable prosthesis associated with good clinical outcome.
