Key Points

To evaluate the effects of femoro-tibial rotational alignment changes on clinical outcomes following total knee arthroplasty.
Analyzed 250 knees undergoing total knee arthroplasty for osteoarthritis
Used axial femoro-tibial rotation measurements before and after surgery
Classified knees based on rotational alignment and changes to assess outcomes
54.4% of knees showed high rotational offset alignment
High offset alignment linked to poorer changes in pain and daily living activities
40.4% of knees experienced significant rotational change, correlating with worse clinical outcomes
