Abstract

Knee instability after prosthetic surgery is one of the major causes of failure. The objective of the study was to evaluate posterior laxity following total knee replacement (TKR) implantation, using a single prosthesis model and comparing polyethylene inserts with medial-pivot (MP) and posterior-stabilized (PS) by means of the evaluation of radiographic images under load ("kneeling view").
