    • "Although the importance of the anterior cruciate ligament (ACL) regarding knee stability, physiologic kinematics, and proprioception is well recognized, to date no bicruciate retaining prosthesis has achieved general acceptance (Nowakowski, 2006). Non-physiologic knee kinematics are generally observed with the use of ACL-sacrificing implants for total knee arthroplasty (TKA), as documented by numerous in vivo studies (Bolanos et al., 1998; Fuchs et al., 2002; Ishii et al., 1998; Lewandowski et al., 1997; Stiehl et al., 1999, 2000). Dennis et al. (1996) found that knees with posterior cruciate retaining (PCR) prostheses perform similarly to non-replaced knees with (ACL) insufficiency. "

    ABSTRACT: A novel tibial baseplate design (Transversal Support Tibial Plateau) as a new treatment concept for bi-cruciate retaining total knee arthroplasty is evaluated for mechanical stability and compared to other tibial baseplate designs. This concept should provide better primary stability and thus, less subsidence, than implantation of two separate unicondylar tibial baseplates. Different baseplates were implanted into synthetic bone specimens (Sawbones® Pacific Research Laboratories, Inc., Washington, USA), all uncemented. Using a standardized experimental setup, subsidence was achieved, enabling comparison of the models regarding primary stability. Overall implant subsidence was significantly increased for the two separate unicondylar tibial baseplates versus the new Transversal Support Tibial Plateau concept, which showed comparable levels to a conventional tibial baseplate. Reduced subsidence results in better primary stability. Linking of two separate baseplates appears to provide increased primary stability in terms of bony fixation, comparable to that of a conventional single tibial baseplate.

    ABSTRACT: Knieprothesen(KTEP) mit mobilen Gleitlagern wurden entwickelt, um eine gegenüber KTEPs mit fixiertem Gleitlager physiologischere Bewegung des Kniegelenks zu gewährleisten. Ziel der Arbeit ist die Untersuchung von Patienten mit einer "fixed"- oder "mobile-bearing" Knietotalendoprothese in der sagittalen Ebene in vivo mit Hilfe der Röntgendurchleuchtung. This study compares in vivo sagittal plane kinematics of two different designs of total knee arthroplasties. Two exercises were recorded using video fluoroscopy
