The innovative revision knee arthroplasty system is used to accurately model the knee prosthesis intra-operatively using various of modular components. The device is based on philosophy of SS'92 and SS'98 Central Rotation Knee, a fully congruent, posterior stabilized knee. The articular surface geometry of the knee's bearing surface is used to minimize pin-point contact stresses to reduce polyethylene wear. Compatible with CRK Resurface Total Knee ensures possibility of partial revisions
