Similarly the radius of curvature at the edges of the femoral component have been changed to reduce the risk of soft tissue impingement. Deupy patients 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.

Discussion The theoretical advantages of a mobile bearing design are attractive, but there has been no convincing evidence that these theoretical advantages translate into a benefit for the patient and deliver a better outcome in the short or long terms.

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.

All patients received a PCL retaining prosthesis which was implanted using a computer-assisted technique. Skgma refer to the other divisions of this site for specific procedures. Also, we reduced confounding factors by the use of two prostheses of similar design from the same manufacturer, consistent PCL status, inclusion of patients with the same form of arthritis and independent assessment of clinical and radiological outcome scores.

Pre- and postoperative deput and difference depug mean change between pre- and postoperative scores. In conclusion, our study showed no statistically significant difference in functional outcome and survivorship between the fixed-bearing and mobile-bearing design of the PFC Sigma knee replacement system in the short-term.

Accessed 30 Oct Statistical analysis Statistical analysis was performed with the use of SAS software v9. No statistically significant difference in any of the outcome scores was found between the groups at a mean follow-up of 5.

Comparison of mobile-bearing and fixed-bearing total knee arthroplasty: Results One hundred twenty patients were recruited for this study. The most recent randomised controlled trial by Higuchi et al. At a mean follow-up of In the “Sigma Curved Plus” insert was introduced, with a raised anterior edge and manufactured using cross-linked polyethylene.

Author information Article notes Copyright and License information Disclaimer. This study shows that there is no statistically significant difference in functional outcome between the cepuy types of implants at short-term follow-up.

Weight-bearing X-rays were taken immediately and one year post surgery to determine the incidence of osteolysis and loosening.

Intra-operative flexibility Address an sihma 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.

It has recently been shown by Cheng et al. All patients received perioperative antibiotic and thromboprophylaxis. Please refer to the package insert and other labeling for a complete list of indications, contraindications, precautions and warnings. 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 siggma as has previously been acknowledged by Biau et al.

Patient-reported outcomes after fixed- versus mobile-bearing total knee replacement: Abstract The aim of this study was to determine whether there is a difference in functional outcome between the PFC Sigma fixed-bearing and rotating-platform total knee replacement systems.

Range of motion was measured using a goniometer with the patient in the supine position. Simultaneous mobile- and fixed-bearing total knee replacement in the same patients. The PCL was retained and the patella resurfaced in all patients. Fixed-bearing versus mobile-bearing total knee arthroplasty: Many different designs for mobile bearings exist, based on a glide or rotating mechanism with uni- or multidirectional motion. This had the same sagittal, coronal and cam geometries as the Sigma CS but the radius from the anterior flange of the femoral sihma 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.

J Bone Joint Surg Am. Simulator studies have shown that this significantly lowers the wear rate compared to standard fixed-bearing knee replacements [ 2 ].
