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.
