What should I look for when choosing?
Manufacturer’s information – does it make sense to you.
What evidence is there for their claims. Are they based on real clinical experience or simulation or logical argument only?
Are there any comparative studies to that show a design supersedes another in criteria that are important to you? Is it more or less stable? Does it score highly in PROMs studies? Are most patients satisfied?
Is the design mentioned in registry reports? Is it similar to the best. The lower the percent at many years, the more likely evidence suggests it will not fail – but remember to note the range of % in brackets if you are looking at a device that is new or not provided by one of the major corporations.
