Il bilanciamento degli spazi e il ripristino della rima articolare nelle protesi totali di ginocchio

The vast majority of articles in the literature supports the concept that a balanced knee is beneficial to the success of total knee arthroplasty. Inadequate restoration of the knee joint line may lead to a poor clinical outcome. The basis of flexion-extension gap balancing is an attempt to obtain equal sized, rectangular gaps in both flexion and extension. In addition, the gap should be rectangular in both flexion and extension. Currently two popular knee replacement techniques are practiced: “measured resection” and “gap balancing”. Both incorporate ligament balancing during the operation, but with differing emphasis. In this article we describe our technique to restore the joint line and to obtain a balanced knee after total knee replacement with the sequences of ligament release in the varus and valgus knee.
