Other
Other related information We investigate whether pre-operative determination of tibial component position using MRI or CT according to the epicondyle axis results in good ROM after total knee arthroplasty.
Subjects are patients performed total knee arthroplasty in accordance with pre-operatively determined antero-posterior axis using MRI or CT from 2016 April 1 to 2018 May 31. We are planning collect 40 subjects.
We evaluate knee joint ROMs 6 months after operation and compare them with the ROMs of knee joints operated before 2016 May 31.
