TC3 Knee System
The SIGMA® Knee System design 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 can 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 improved intra-operative flexibility.
