Depuy | PFC Sigma Knee System

Journey Deuce Knee Replacement Manufacturer: Between November and Pc patients who underwent a primary total knee arthroplasty for osteoarthritis under the care of two orthopaedic surgeons senior authors were invited to take part in this study.

The study population, however, was derived from an Asian population with a comparably low mean height and weight. Accessed 30 Oct The treatment allocation was concealed in sequentially numbered, darkened, sealed envelopes. Sign in Forgot Details?

Introduction Mobile bearings in total knee arthroplasty have been developed with the aim to better reproduce the complex function and kinematics of the knee joint [ 1 ].

Results of this combination have not been previously reported. The content on this page is intended for Healthcare Professionals. In recent years a number of studies have investigated the functional outcome of the PFC Sigma fixed-bearing and PFC Sigma rotating-platform total knee replacement systems [ 12 — 17 ].

Twenty-year evaluation of meniscal bearing and rotating platform knee replacements. Mean flexion did not increase in either group, but mean extension improved significantly in both groups.

Difficulties with bearing dislocation and breakage using a movable bearing total knee replacement system. None of these studies showed a statistically significant difference between the mobile and fixed bearing, but the use of different types and designs of implants may have affected the clinical outcome as has previously been acknowledged by Biau et al. At a mean follow-up of Based on the current results no type of bearing can be recommended over the other.

Our randomised controlled trial of 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 Total Knee Arthroplasty TKA and Unicompartmental Knee Replacement are intended to provide increased patient mobility and reduce pain by replacing the damaged knee joint articulation in patients where there is evidence of sufficient sound bone to seat and support the components.


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. Statistical analysis Statistical analysis was performed with the use of SAS software v9.

Registration is quick and free. However, in our trial the PCL was retained in all cases, all implants were cemented and the patella was not resurfaced. The authors showed no statistically significant difference in postoperative knee scores, but found statistically significantly better results for isokinetic muscle force in flexion and medio-lateral stability in flexion for the rotating bearing group.

The PCL was retained and the patella resurfaced in all patients. Find out more here.
