Hi all,

I work with a group of Orthopaedic Surgeons who would like to
investigate whether the mobile bearing of a total knee replacement moves
in vivo during dynamic activities. It is envisaged that the patients would
be performing flexion and extension of the knee while weight bearing.

We have looked through the available literature but are still unsure of
what technique we should be using to collect the data that we require.
We are considering the use of Roentgen Stereophotogrammetric
Analysis (RSA). Can RSA be used to investigate dynamic activities such
as knee flexion and extension during weightbearing? If not is there a
better technique eg video fluroscopy?

Any replies will be collated and posted for your viewing pleasure.

Thank you in advance.
