Intended Use MicroPort Total Knee Systems are indicated for use in knee arthroplasty in skeletally mature patients with the following conditions: - 1) noninflammatory degenerative joint disease including osteoarthritis, traumatic arthritis, or avascular necrosis: - 2) inflammatory degenerative joint disease including rheumatoid arthritis; - 3) correction of functional deformity: - 4) revision procedures where other treatments or devices have failed; and treatment of fractures that are unmanageable using other techniques. ADVANCE® 913 Medial Pivot Tibial Base and Insert Components (not licensed for sale in Canada) are for use with bone cement. Porous-Coated Total Knee Replacement Components are for use without bone cement. The EVOLUTION® Total Knee System is for cemented use only. #### B. Device Description The subject devices for this submission are all the predicate devices listed above, which consists of implant components used in knee arthroplasty. The only changes to the subject devices are updates to their labeling. Specifically, the package inserts and package labels are being updated to include MR Conditional language and symbols. The subjects are identical to the predicates in all aspects except for the labeling updates. Testing is provided in this Traditional 510(k) that establishes the conditional safety and compatibility of the passive implants in a magnetic resonance (MR) environment. The basic design features are the following: - Metal Femoral component manufactured from cobalt chrome alloy ● - Femoral components available in porous and non porous versions - Tibial inserts manufactured from UHMWPE - Tibial bases manufactured from cobalt chrome alloy or titanium alloy ● - Tibial bases available in porous and non porous versions ● - All-poly patellae manufactured from UHMWPE - Metal portion of metal backed patellae manufactured from titanium allov . ## C. Substantial Equivalence Information Since this submission is only regarding device labelling change, the design features and materials of the subject devices are identical to those of the predicate devices. The indications for use are identical to the predicate devices. The safety and effectiveness of the subject devices are adequately supported by the substantial equivalence information, materials information, and analysis data provided within this Premarket Notification. {6}------------------------------------------------ #### D. Nonclinical Testing Non clinical Testing was conducted to establish the conditional safety and compatibility of the passive implants in a magnetic resonance (MR) environment according to the recommendations provided in the guidance document "Establishing Safety and Compatibility of Passive Implants in the Magnetic Resonance (MR) Environment" issued on December 11, 2014. Testing was also conducted according to the following standards: ASTM F2052-14. "Standard test method for measurement of magnetically induced displacement force on passive implants in the magnetic resonance environment"; ASTM F2119-7 "Standard Test Method for Evaluation of MR Image Artifacts from Passive Implants": ASTM F2503-13 "Standard Practice for Marking Medical Devices and Other Items for Safety in the Magnetic Resonance Environment"; ASTM F2182-11a "Standard Test Method for Measurement of Radio Frequency Induced Heating near Passive Implants During Magnetic Resonance Imaging" The tests determined the effects of the MRI on the implants, and the effects of the implants on the image quality. The tests evaluated the worst case components and constructs for RF Heating, field interactions, and image artifacts. The testing concluded that there are no safety issues related to magnetic field interactions under specific conditions identified in the labeling. ## E. Clinical Testing Clinical data was not provided for the subject devices. #### F. Conclusion All the information provided in this submission adequately supports the substantial equivalence of the labelling change.
