• This device is indicated for:
– Moderate to severe knee instability
– Significant bone loss and/or ligament deficiencies caused by neoplasms, trauma, rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis, collagen disorders, and/or avascular necrosis of the proximal and/or distal femur and/or proximal tibia
– Valgus, varus or flexion deformities
– The salvage of previously failed surgical attempts
• A total femoral replacement construct consisting of MOST Options or Segmental proximal femoral, Segmental System segments and Segmental System distal femoral components may be used without cement.
• Variable Stiffness stem extensions require the use of either a smooth or Trabecular Metal stem collar, which must be cemented to the stem. Following cementing to the stem, the smooth collar must be cemented against the bone. The remainder of the stem must be used uncemented.
• Fluted stem extensions require the use of either a smooth or Trabecular Metal stem collar, which must be cemented to the stem. Following cementing to the stem extension, the smooth collar must be cemented against the bone. The remainder of the stem must also be cemented against the bone.
• The Trabecular Metal collar may be used cemented or uncemented against the bone.
• All other constructs are for cemented use only.
Indications for use as stated in the FDA summary.
