Abstract (en)

[origin: WO2006078236A1] Systems, methods and processes for computer-assisted soft tissue balancing, including ligament balancing, determining surgical cuts, and positioning or placement of the components of the prosthetic knee during TKR. The improved methods, systems, and processes consider and correlate anatomical landmarks and dynamic interactions of the knee bones and soft tissues. The improved methods, systems and processes resolve several problems related to the prosthetic knee component positioning and soft-tissue balancing during computer-assisted TKR. The improved methods, systems and processes are flexible and versatile, provide reliable recommendations to the surgeon, and improve restoration of the knee function and patient recovery. The computer stores in its memory a logic matrix for assessing kinematics of the knee, and provides output in the form of recommendations on soft tissue balancing.
