Posterior cruciate ligament resection in total knee arthroplasty

Abstract

PCL resection creates flexion-extension mismatch by increasing the flexion gap more than the extension gap. The increase in the lateral flexion gap is greater than the increase in the medial flexion gap, which creates mediolateral laxity in flexion. Improvements in FFD following PCL resection are dependent on the degree of deformity before PCL resection. Cite this article: <i>Bone Joint J</i> 2019;101-B:1230-1237.
