Effect of rotational alignment on outcome of total knee arthroplasty.

ABSTRACT:

Background and purpose

Poor outcomes have been linked to errors in rotational alignment of total knee arthroplasty components. The aims of this study were to determine the correlation between rotational alignment and outcome, to review the success of revision for malrotated total knee arthroplasty, and to determine whether evidence-based guidelines for malrotated total knee arthroplasty can be proposed.

Patients and methods

We conducted a systematic review including all studies reporting on both rotational alignment and functional outcome. Comparable studies were used in a correlation analysis and results of revision were analyzed separately.

Results

846 studies were identified, 25 of which met the inclusion criteria. From this selection, 11 studies could be included
