Change in mechanical axis alignment highly correlates with increased limb loading after total knee arthroplasty

摘要

Aims and Objectives: Mechanical axis of the lower limb assessed in standing long-leg radiographs was demonstrated to change within the first three postoperative months after total knee arthroplasty (TKA). The underlying mechanism including the influence of limb loading for the change in mechanical axis alignment after TKA has not been evaluated so far.
