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. P -values of less than 0. There was no statistically significant difference in clinical and radiological outcomes between the groups at a mean of 7.
A comparison eepuy fixed-bearing and mobile-bearing total knee arthroplasty at a minimum follow-up of 4. All medical devices have associated risks. At a mean follow-up of Long-term follow-up will determine if there is an increased rate of wear or loosening in either group.

No analysis for improvement in scores was reported. Please refer to the other divisions of this site for specific procedures.

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 pc to seat and support the components. Medial Rotation Knee Manufacturer: All medical devices have associated risks.
The weaknesses of our trial include a relatively high rate slgma exclusion from analysis and loss to follow-up. Intra-operative flexibility Address an array of patient needs OR efficiency with common tibial base and preparation as used in higher constrained implant options Allows for bearing rotation that reduces torsional stresses on tibial base 1. Patients were not blinded to the knee type implanted.
Clin Orthop Relat Res.
Comparison between mobile-bearing and fixed-bearing knees in bilateral total knee replacements. All patients received a PCL retaining prosthesis which was implanted using a computer-assisted technique.
The operation was carried out through a midline incision using a medial parapatellar pfcc.

J Bone Joint Surg Am. Patients and methods Between November and July patients who underwent a primary total knee arthroplasty for osteoarthritis under the care of two orthopaedic surgeons senior authors were invited to prc part in this study. The study population, however, was derived from an Asian population with a comparably low mean height and weight. 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 may therefore not be transferable to a western European population. Signa age at surgery was In all patients a posterior-stabilised implant was used and the patella resurfaced.

Patients and assessors were not blinded with regards to the implant they received, which could have influenced the outcome in favour of the mobile bearing. Simultaneous mobile- and fixed-bearing total knee replacement in the same patients.

A tourniquet was applied routinely.
