The operations were performed sigmx or under direct supervision of the two orthopaedic surgeons. The functional outcome was evaluated by an independent physiotherapist or specialist nurse practitioner who was not blinded to the knee implanted, using range of motion, Oxford knee score range 12—60 [ 18 ] and Knee Society KSS knee and function subscores range 0— [ 19 ].

The patella was not resurfaced. The prostheses were found to be well fixed and without evidence of loosening in both cases. All inquiries can be submitted by email to: Total Knee System introduced inP. Resources Bespoke Report P. Our randomised controlled trial eepuy patients who underwent unilateral knee replacement for osteoarthritis showed no statistically significant difference in functional outcome and survivorship between the mobile-bearing and rotating-platform in the PFC Sigma total knee replacement at a mean of There were no revisions at the one-year time point for early infection, loosening or bearing dislocation in either of the groups.


In two of these studies [ 1516 ] the patella was routinely resurfaced; in the third study the resurfacing status of the patella was not reported. Allows for either rotating platform or fixed bearing tibial constructs Only company to provide rotating platform in the revision constraint varus valgus constraint level.

The study population, however, was derived from an Asian population with a comparably low mean height and weight. Journal List Int Orthop v.

However, in our trial the PCL was retained in all cases, all implants were cemented and the patella was not resurfaced. This left patients for analysis. For the subsequent patients a further randomisation schedule, blocked and stratified for treatment only, was produced by a biostatistician at DePuy International Ltd.

Indus HiFlex Knee Manufacturer: The allocated envelope was opened on the day before surgery by the operating surgeon after consent had been obtained.

A clinical assessment was carried out preoperatively and at a minimum of one year after surgery. Patients were included if they were suitable for treatment with either a fixed- or mobile-bearing knee replacement system and had given written informed consent. The Cochrane Review [ 11 ] highlighted that there were only few comparative studies with acceptable methodological quality [ 45 ].
