The LCS® Total Knee System widely established and validated the fundamental design
principles of low contact stress and bearing mobility. now The first design to combine
congruency with mobility in a tri-compartmental knee implant, the LCS knee was also
the first mobile bearing system to undergo a rigorous multi-center clinical evaluation
(IDE/PMA) in the United States before launch. With more than 24 years of clinical
experience, the LCS Total Knee System offers an unparalleled record of success.
This success is grounded in a combination of factors:
• Maximum contact area and corresponding low contact stress at the patello-femoral
and femoro-tibial bearing interfaces reduces the potential for polyethylene wear
and catastrophic damage.
• Postoperative self-alignment of the mobile-bearing maintains maximum contact area
while diffusing torsional and shear forces that can contribute to implant loosening.
For more than two decades, the LCS knee has established a clinical track record
that makes it one of the gold standards in total knee replacement (TKA):
• The incidence of patello-femoral complications, one of the most common causes
of revision TKA, is reported in notably few cases throughout extensive clinical
follow-up.2-4
• Long-term implant survivorship exceeds 96 percent in major peerreviewed clinical
studies.
