AltrX™ was built on the proven clinical heritage of Marathon® cross-linked polyethylene. Introduced in 1998, Marathon was the first FDA-cleared cross-linked polyethylene in orthopaedics.
In femoral revision arthroplasty, removal of well-bonded cement can be extremely difficult, time consuming and damaging to the remaining bone. Improved cementing techniques and removal of implants for reasons other than loosening also have added to the problem of femoral revision. This is especially true if cement is located beyond the anterior bow of the femur. Removal of cementless, proximally fixed or extensively coated femoral implants may also be an extreme challenge.
