Factors Affecting Wear of Constrained Polyethylene Tibial Inserts in Total Knee Arthroplasty

Wear in posterior-stabilized (PS) polyethylene tibial inserts depends on component position, limb alignment, and ligament balancing. Valgus-varus constrained (VVC) inserts are likely to be affected similarly. We aimed to compare wear characteristics of VVC and PS inserts and identify associated fact...
