Distal Femoral Modular Replacement System
The GMRS System is designed to meet the unique needs of patients who require reconstruction of large segmental defects for tumors, failed previous arthroplasty, or trauma. This system is designed to:
- Reconstruct large segmental defects of the knees
- Reconstruct osteoarticular defects of varying sizes
- Allow for variation and intra-operative changes of the surgical plan
The system consists of distal femoral components, extension pieces, and stems. It also includes a complete set of trial components and instrumentation. The distal femur is designed to improve patella kinematics. It has a deepened patellar track that articulates with the Duracon patella. The GMRS standard Distal Femur accepts the Modular Rotating Hinge (MRH) Tibial Rotating Component, Bushings, Axle and Bumper for seamless integration with the MRH resurfacing Tibial Base plate.
Distal Femoral Components – These are available in two sizes: small and standard; both sizes are available in left and right configurations. All distal femoral components have a built-in 6-degree valgus offset and use the Modular Rotating Hinge Knee components.
Cemented Stems – The GMRS cemented atems are available in three styles: straight, curved and long curved. Each stem comes with or without an extra-cortical, porous-coated body section.
Extension Pieces – The extension pieces feature a male and female taper, which attach a stem to a Distal Femoral component. These extension pieces are used to customize the replacement length and are available in several different sizes.
