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.

Since publication of the Cochrane review further studies have been reported, comparing mobile and fixed-bearing knee replacement systems. In the titanium tibial base plate was changed to a highly polished cobalt chrome version.

Correlation of maximum flexion with clinical outcome after total knee replacement in Asian patients.

Please sign in to view this content TKA is indicated for: Patient-reported outcomes after fixed- versus mobile-bearing total knee replacement: This article has been prc by other articles in PMC. Statistical analysis Statistical analysis was performed with the use of SAS software v9. These include randomised controlled trials [ 6 — 815 — 1723 ], prospective ddpuy series [ 910 ] and retrospective reviews [ 12 — 1424 ]. Unicompartmental Knee Replacement is indicated in these conditions if only one side of the joint medial or lateral is affected.


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.

Sigka hundred twenty patients were randomised to receive either a fixed-bearing or rotating-platform PFC Sigma total knee replacement. This however seems unlikely as the use of the mobile bearing was not associated with a better outcome.

If you are a patient, click here. Journey Deuce Knee Replacement Manufacturer: The study population, however, was derived from an Asian population with a comparably low mean height and weight. 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.


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.
