Dear Jose:
this is not the first time we see requests like your.
Unfortunately, all research labs that have such models usually
obtained them because of an industrial research contract, which
typically excludes the possibility of making available to third
parties the prosthetic models we receive form the companies.

As Biomechanics community, I guess we should try to convince the
orthopaedics companies to make available in the public domain the CAD
models of at least those designs that are not in production anymore.
this would be particularly useful for those designs that were retired
because of poor performances. I guess having the CAD model of the 3M
Capital prosthesis would be extremely interesting for many of us.

I am posting this reply on the lists because I would like to hear
from those colleagues working in companies or in regulatory bodies
whether this is in their opinion a feasible idea, and under which

Best regards
