Functional description

The GMK Sphere Primary Femur is TiNbN Coated and is designed for cemented use in total knee

arthroplasty. The main purpose of the TiNbN coating is to limit the ion release from the underlying alloy.

The design of the GMK Sphere is characterized by a spherical medial femoral condyle and an

asymmetrical fixed tibial UHMWPE insert with a concave spherical medial compartment. This tibial-femoral

combination allows the medial "ball-in-socket" mechanism.

Intended purpose

Total Knee Prosthesis designed for tricompartmental replacement of the natural knee joint and intended to

provide increased patient mobility and reduced pain by replacing the damaged knee joint, if there is

evidence of sufficient sound bone to seat and support the components. Candidates for total knee

replacement are patients with a severely painful and/or severely disabled joint as a result of osteoarthritis,

post-traumatic arthritis, rheumatoid polyarthritis, or primary implantation failure. If, in the opinion of the

surgeon, an unequivocal indication for total knee replacement outweighs the risks associated with the age

of the patient, and if limited demands regarding activity and knee joint loading can be assured, total knee

replacement may be considered for young patients. This includes severely disabled patients with multiple

joint involvement for whom and immediate gain in knee mobility may lead to significant improvement of

their quality of life.
