Only three of these are randomised controlled trials [ 15 — 17 ]. This study shows that there is no statistically significant difference in functional outcome between the two types of implants at short-term follow-up. Author information Article sogma Copyright and License information Disclaimer. Inconsistent reporting did not allow for meta-analysis of the data. 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.

This is intended to substitute for the PCL without using a posterior stabilised component. Intramedullary referencing was used for the femur and extramedullary referencing for the tibia. We also did not encounter any bearing dislocations, which has been described as a potential complication of mobile-bearing implants in other studies [ 2627 ]. This study was approved by the local research ethics committee.

Comparison between mobile-bearing and fixed-bearing knees in bilateral total knee replacements. Available sigm posterior cruciate retaining or posterior stabilized femoral component designs, and fixed and mobile-bearing tibial component designs, this knee system is designed to provide surgical solutions for a variety of clinical indications. They were analysed for osteolysis and signs vepuy loosening by an independent radiograph reviewer using the Knee Society roentgenographic evaluation and scoring system [ 21 ].

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

Comparison of mobile-bearing and fixed-bearing total knee arthroplasty: All implants were posterior stabilised, cemented and the patella was resurfaced in all cases.

All inquiries can be submitted by email to: 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 pdc of arthritis and independent assessment of clinical and radiological outcome scores. Please refer to the other divisions of this site for specific procedures.

We also used common outcome measures and aimed to report data in a standardised way to enable inclusion of the data in future meta-analyses.
