Knee Arthroplasty Component Malrotation Does Not Affect Function or Quality of Life in the Short to Medium Term

摘要

Background: Component rotation in total knee arthroplasty is thought to affect patella tracking, flexion gap, and balancing and hence is hypothesized to affect function, pain, and longevity. Few studies have directly correlated post-operative component rotation to function and quality of life in the short to medium term post-operatively, with findings in the current literature conflicting.
