I am a graduate student at Marquette University desinging my
thesis project to compare the Otto Bock 3R80 knee unit and the Total
Knee by Ossur. I will be looking at the hip moments for stance
stability and swing initiation for these two devices. I am trying to
conduct a power analysis to determine the number of subjects I will
need, and am having trouble finding data, specifically for the Total
Knee. I have one study with 7 subjects that has data for the 3R80 knee,
though the data is only presented graphically and is not tabulated. For
the total knee I have only been able to find 1 study with data, and
this study has 1 subject and does not present hip moment data. I have
also found a few other studies with similar types of knees. Below is a
list of the references I have found for this topic. If anyone has any
data or references that might contain data for the hip moment for
either of these devices, I would greatly appreciate your passing it
along to me.
Sincerely,
