Read the full statement (267 words)

The Howmedica Total Stabilizer Knee Components (Stabilizer femoral component, stabilizer tibial insert, modular offset adaptor, femoral/tibial stem extenders and tibial wedges) are intended to be used along with previously released Duracon tibial and patellar components as a total knee system in primary or revision cemented total knee arthroplasty. This total knee system IS intended to be used to relieve pain and instability of the knee joint as a result of non-inflammatory joint disease, inflammatory joint disease, trauma, or failed previous prosthesis.

The Howmedica Total Stabilizer femoral component and tibial insert components are specifically intended to be used when the cruciate ligaments are absent, inadequate, or cannot be preserved during the operative procedure, especially when anterior-posterior stability is impaired due to the absence of the patella. The collateral ligaments may or may not be intact. In addition, these components may be used in revision of a failed previous prosthesis where the cruciate ligaments are absent.

The Howmedica tibial wedges are intended to be used with the Howmedica Universal tibial baseplate to augment bone loss on the surface of the tibia. Tibial bone loss may be observed in primary or revision total knee arthroplasty.

The Howmedica Modular Offset Adaptor is intended to be used in situations where a stem extender is being used, and the tibial baseplate or femoral component requires offsetting to allow optimal coverage of the prepared bone surfaces.

The Howmedica Stem Extenders are intended to be used with Duracon/ Kinemax femoral/tibial components in primary/revision total knee arthroplasty where additional stability is required.

The Howmedica Total Stabilizer Knee Components are intended to be implanted using bone cement.
