A number

2、 in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers total knee replacement (TKR) is intended to cover all the widely used generic types of kneereplacement prostheses u

This includes total knee replacement (TKR) and unicondylar knee replacement(UKR) prostheses of both fixed and mobile bearing varieties, and for prima

4、ry or revision surgeries.Although a patellar componentmay be considered an integral part of a TKR, the detailed description of this component is excluded here since it is provided inSpecification F1672.1.2 Included within the scope of this specification are replaceable components of modular designs,

5、 for example, tibialarticulating surfaces and all components labeled for, or capable of, being used with cement, regardless of whether the samecomponents can also be used without cement. This includes primary and revision prostheses and also covers fixed and mobilebearing knee designs.1.3 This speci

6、fication is intended to provide basic descriptions of material and prosthesis geometry. Additionally, thosecharacteristics determined to be important to in vivo performance of the prosthesis are defined. However, compliance with thisspecification does not itself define a device that will provide ade
