Clinical outcomes (ROM, AKS and WOMAC scores, and side preference), evaluated at 6, 12 and 24\u00a0months postoperatively, were compared between knees fitted with the MB prosthesis (e.motion\u2010FP) or the FB prosthesis (Genesis II) in 66 patients who underwent bilateral TKA. In addition, the same comparisons between the knees fitted with the MB prosthesis and the knees with the FB prosthesis were made separately in the subgroup of 33 patients implanted with a cruciate retaining FB (FB\u2010CR) prosthesis and the other subgroup of 33 patients with a posteriorly stabilized FB (FB\u2010PS) prosthesis in a knee. The floating platform MB prosthesis achieved comparable clinical outcomes to the FB prosthesis. No significant differences were found between the FB\u2010 and MB\u2010implanted sides at any time with respect to the outcome scales, and temporal patterns were similar. However, comparisons of FB\u2010CR and FB\u2010PS patient groups revealed different temporal patterns. In the FB\u2010CR group, most outcome scales were improved at 6\u00a0months, peaked at 12\u00a0months and then remained at this level at 24\u00a0months. In contrast, outcomes in the FB\u2010PS group improved much faster to almost peak at 6\u00a0months, and then remained at this level. In the FB\u2010CR group, more patients preferred the knee with fitted with a MB prosthesis at 6\u00a0months. In contrast, in the FB\u2010PS group, no side preference for the MB prosthesis was observed, and more patients preferred knees implanted with the FB prosthesis at 12 and 24\u00a0months. This study demonstrates that this new mobile\u2010bearing prosthesis, designed as a floating platform, provides satisfactory clinical performances that are comparable to those achieved using the established fixed\u2010bearing prosthesis in terms of clinical outcomes.<\/jats:p>","DOI":"10.1007\/s00167-009-0985-8","type":"journal-article","created":{"date-parts":[[2009,11,27]],"date-time":"2009-11-27T22:52:40Z","timestamp":1259362360000},"page":"879-888","source":"Crossref","is-referenced-by-count":19,"title":["Early
