The SIGMA® Knee System design is the most constrained device available within the P.F.C.® SIGMA® Knee System and is indicated for use in cases where collateral ligaments are deficient. This comprehensive system offers both a fixed bearing and rotating platform option. Additionally surgeons are able to address bone and soft tissue defects with a variety of products including augments, wedges, stems, and metaphyseal sleeves. This system’s approach to revision knee surgery provides the surgeon with maximum intra-operative flexibility.
Total knee arthroplasty is intended to provide increased patient mobility and reduced pain by replacing the damaged knee joint articulation in patients where there is evidence of sufficient sound bone to seat and support the components. TKA is indicated for: a severely painful and/or severely disabled joint resulting from osteoarthritis, post-traumatic arthritis, rheumatoid arthritis, or a failed previous implant.
