Uitkomstmaten
Primaire uitkomstmaten
Rotational degrees of freedom of the tibial implant, measured with 3-D motion analysis after operation and compared between the XP tibia implant and CR conventional tibia implant operated with either the MRI-based Signature™ guide or the Conventional alignment
Achtergrond van het onderzoek
The aim of the present prospective randomized clinical trial was to evaluate and compare the rotational laxity and stiffness after TKA with or without preservation of the ACL using 3-D motion analysis for evaluation of rotational biomechanics with the ability to forget the artificial knee joint in everyday life can be achieved as the ultimate goal in joint arthroplasty resulting in the greatest possible patient satisfaction. We hypothesized that preservation of the ACL would result in better rotational stability than TKA without ACL
Doel van het onderzoek
•Bicruciate preserved tibia tray for TKA is at least as efficient and safe as the conventional tibia tray for TKA with elimination of the ACL.
•TKA with the use of Signature™ alignment guide is at least as efficient and safe as TKA with the use of conventional intramedullary alignment guiding.

Onderzoeksproduct en/of interventie
The Vanguard™ XP total knee system is a cruciate retaining design that allows for the posterior cruciate ligament (PCL) and the anterior cruciate ligament (ACL) to be preserved while incorporating geometry to accommodate and enable the natural function of the ligaments of the knee.
The Vanguard XP implant will be compared with the Vanguard CR implant. The Vanguard™ Complete Knee System features complete interchange ability and multiple sizing options making it the most comprehensive total knee system available, allowing surgeons to provide personalized patient care due to independent fit of the femoral, tibial and patellar components without preservation of the ACL
