(EN) GUIDE ASSEMBLY FOR GUIDING CUTS TO A FEMUR AND TIBIA DURING A KNEE ARTHROPLASTY
(FR) ENSEMBLE GUIDE POUR GUIDER DES DECOUPES SUR UN FEMUR ET UN TIBIA LORS D'UNE ARTHROPLASTIE DU GENOU
Abstract
(EN)

An assembly for guiding resection of a femur and tibia of a knee joint in
preparation for installing a femoral and tibial knee components. For example,
the
assembly can include tibial and femoral IM rods to which are connected through
a
torque bolt that allows controlled adjustment of the distraction of the tibia
and
femur during cut positioning in a range of flexion angles. Also, the assembly
is
usable with relatively small, noninvasive approaches to the knee joint by way
of
relatively narrow, low profile components that attach to tibial and femoral IM

rods. Further, the assembly includes several quick-release components to allow

fast assembly and disassembly in a surgical setting. Each of these aspects,
along
with the ability of the assembly to accurately guide initial reference cuts to
the
tibia and femur, promotes an improved outcome for the patient.
