All patients received a PCL retaining prosthesis which was implanted using a computer-assisted technique. Two-year follow-up on joint stability and muscular function comparing rotating versus fixed bearing TKR. Weight-bearing X-rays were taken immediately and one year post surgery to determine the incidence of osteolysis and loosening.
Conflict of interest This study has been sponsored by DePuy International who have provided resources to cover the additional costs of conducting the research over and above standard clinical practice as well as statistical support. Many different designs for mobile bearings exist, based on a glide or rotating mechanism with uni- or multidirectional motion.

Please refer to the package insert and other labeling for a complete list of deput, contraindications, precautions and warnings. Total knee arthroplasty is intended to provide increased patient mobility and reduced pain by replacing the damaged knee joint articulation in patients where there is evidence of sufficient sound bone to seat and support the components.
There was also a statistically significant difference in preoperative scores between the groups, but no difference in postoperative scores. In the “Sigma Curved Plus” insert was introduced, with a raised anterior edge and manufactured using cross-linked polyethylene. The primary outcome measure was active sigmma of motion ROM at one year after surgery. Mean flexion did not increase in either group, but mean extension improved significantly in both groups.

The rotating platform, as used in the PFC Sigma RP knee replacement system, has unidirectional motion which has been shown to have sivma volumetric wear than other mobile designs [ 12 ]. This had the same sagittal, coronal and cam geometries as the Sigma CS but the radius from the anterior flange of the femoral component to the box for the tibial peg was increased, with the aim of reducing the risk of “patellar clunking” in the box and to change the tracking of the patellar component in flexion.
It has recently been shown by Cheng et al. We carried out a randomised controlled trial comparing the functional outcome and survivorship between the fixed-bearing and rotating-platform PFC Sigma knee replacement systems. The patella was not resurfaced.

Overview of published studies comparing fixed-bearing and rotating-platform PFC Sigma knee replacement systems. Inconsistent reporting did not allow for meta-analysis of the data. At a mean follow-up of In these studies a variety of knee replacements have been used, but often prostheses of different design and different manufacturers were compared with each other [ 6 — 10 ].

The sample size was calculated based on detecting a difference of 20 degrees in the postoperative range of motion ROM between the fixed- and mobile-bearing knee systems. In recent years a number of studies have investigated the fpc outcome of the PFC Sigma fixed-bearing and PFC Sigma rotating-platform total knee replacement systems [ 12 — 17 ].
