The SIGMA® Knee System offers one of today’s most comprehensive, integrated knee systems. Based on the clinically successful P.F.C.® Total Knee System introduced in 1984, the SIGMA Knee continues a history on innovation based on clinical evidence.
The SIGMA Knee embraces a wide variety of surgeon philosophies and surgical techniques, while providing function, clinical results, and a variety of options for today’s patients. Available in posterior cruciate retaining or posterior stabilized femoral component designs, and fixed and mobile-bearing tibial component designs, this knee system is designed to provide surgical solutions for a variety of clinical indications.
Total Knee Arthroplasty (TKA) and Unicompartmental Knee Replacement are intended to provide increased patient mobility and reduce pain by replacing the damaged knee joint articulation in patients where there is evidence of sufficient sound bone to seat and support the components. The SIGMA Cruciate Retaining Knee femoral components with POROCOAT® Porous Coating are intended for cemented or cementless use as the femoral component of a Total Knee Replacement System. TKA is indicated for: a severely painful and/or disabled joint from osteoarthritis, traumatic arthritis, rheumatoid arthritis or a failed previous implant. Unicompartmental Knee Replacement is indicated in these conditions if only one side of the joint (medial or lateral) is affected.
