Original message:

Dear Subscribers,

I am writing to ask for help in finding information on the geometry of
total knee replacement components. I am looking at the effects of
ligament imbalance in total knee replacement surgery and require
information on the specific geometry of the femoral and tibial
components. This information is not easily obtained from the
manufacturers and I have not been able to find published data.

Any help would be greatly appreciated. A summary of replies will be

Thanks for your help,

-A study about the ligaments influence in total knee replacement is
reported in our paper Martelli S. et al. , J Arthroplasty , v.13, n.2,
1998, pp. 145-155, for INTERAX prosthesis.
