Erratum to: Normal Femorotibial Rotational Alignment and Implications for Total Knee Arthroplasty: an MRI Analysis

Background Rotational alignment of prosthetic components in total knee arthroplasty (TKA) is important to successful outcomes. Component malrotation is a known cause of revision and understanding normal rotational alignment may help recreate normal joint kinematics. To date, no large MRI study assessing femorotibial rotational alignment in nonarthritic knees has been undertaken.
