Data were analysed on an intention-to-treat analysis. The prostheses were found to be well fixed and without evidence of loosening in both cases. Revision Tray Surgical Technique. The posterior cruciate ligament PCL was retained in all cases. SIGMA is designed to address implant longevity by maximizing femoro-tibial contact area, minimizing peak contact stresses while employing state-of-the-art polyethylene sterilization and packaging.

They allow a more natural tibial rotation during flexion than fixed-bearing implants. Twelve pff were lost to follow-up—six patients did not attend the follow-up clinics, four patients died within the first year after surgery of causes unrelated to the operative procedure and two patients withdrew consent.

Journal List Int Orthop v. All prostheses were cemented. 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.

Difficulties with bearing dislocation and breakage using a movable bearing total knee replacement system. For the subsequent patients a further randomisation schedule, blocked and stratified for treatment only, was produced by a biostatistician at DePuy Pgc Ltd. J Bone Joint Surg Br. 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 ].

No statistically significant difference in any of the outcome scores was found edpuy the groups at a mean follow-up of 5. Two-year follow-up on joint stability and muscular function comparing rotating versus fixed bearing TKR.

This study was approved by the local research ethics committee. The rotating platform, as used in the PFC Sigma RP deput replacement system, has unidirectional motion which has been shown to have less volumetric wear than other mobile designs [ 12 ].

There were no intraoperative complications. All femoral and tibial components were cemented. No analysis for improvement in scores was reported.

Results may therefore not be transferable to a western European population.
