1.1''This specification is intended to cover all the widely used generic types of knee replacement prostheses used to provide functioning articulation. This includes total knee replacement (TKR) and unicondylar knee replacement (UKR) prostheses of both fixed and mobile bearing varieties, and for primary or revision surgeries. Although a patellar component may be considered an integral part of a TKR, the detailed description of this component is excluded here since it is provided in Specification F1672.

1.2''Included within the scope of this specification are replaceable components of modular designs, for example, tibial articulating surfaces and all components labeled for, or capable of, being used with cement, regardless of whether the same components can also be used without cement.

1.3''This specification is intended to provide basic descriptions of material and prosthesis geometry. Additionally, those characteristics determined to be important to in-vivo performance of the prosthesis are defined. However, compliance with this specification does not itself define a device that will provide adequate clinical performance.

1.4''Excluded from the scope are hemiarthroplasty devices that replace only the femoral or tibial surface, but not both; and patellofemoral prostheses. Also excluded are devices designed for custom applications.

1.5''The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6''This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7''This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
