Form factor: 9 mm tibial articular surface. Design: Curved in frontal and sagittal planes; snap-fit attachment to tibial plates. ## Regulatory Identification A knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a knee joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a tibial component or components and a retropatellar resurfacing component made of ultra-high molecular weight polyethylene. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027). ## Predicate Devices - MG II® Total Knee System - Insall/Burstein® II Modular Knee System ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Box 708 Warsaw, Indiana 46581-0708 - Prepared by: Ruth Ann Wood Regulatory Affairs Associate - Date: March 15, 1995 - Trade Name: NexGen™ Total Knee Solution 9 mm Tibial Articular Surface - Classification Name: Knee joint patellofemorotibial polyethylene/metal/polyethylene semiconstrained cemented prosthesis 21 CFR 888.3560. - Identification of the Predicate Device: MG II® Total Knee System and Insall/Burstein® II Modular Knee System - Summary Description: The NexGen™ Complete Knee Solution, 9 mm articular surfaces are made of molded ultra-high molecular-weight polyethylene (UHMWPE). As with the MG II Knee, each Page 1 1 219 A Bristol-Myers Squibb Company {1} articular surface is snapped into one of a series of the NexGen Knee tibial plates. The components are curved in both the frontal and sagittal planes. The posterior stabilized version having slightly more curvature in the anterior portion of the sagittal plane. - Summary of Intended Uses: The device is intended to reduce or relieve pain and restore function and motion to the knee joint. - Comparison to the Predicate Device: The 9 mm tibial articular surfaces have the same basic geometric shape, intended use and material as the predicate device. - Clinical and Nonclinical Data: Numerous studies reported in the literature for the predicate devices indicate that satisfactory results have been obtained through the use of 9 mm tibial articular surfaces.
