Device Description The Prolixus™ Cruciate Retaining (CR) Total Knee System consists of three primary components: Cruciate Retaining (CR) Femoral Component, Cruciate Retaining (CR) Tibial Insert, Patellar component and Tibial base plate. ### The Prolixus™ CR components are described below: PROLIXUSTMTotal Knee Cruciate Retaining (CR) Femoral Component Prolixus™ Total Knee Cruciate Retaining (CR) Femoral Component is fabricated from cast cobalt-chromium-molybdenum alloy, and is intended for cemented application to replace the articulating surface of the distal femur. This cruciate retaining femoral component is utilized when total knee replacement is indicated, and accommodates the posterior cruciate ligament if it is present. The Cruciate Retaining (CR) Femoral Component is available in right and left configurations, and six proportional sizes (sizes A to F) to accommodate differences in patient anatomy. The interior surface of the component is grit-blasted to increase surface roughness - this is intended to promote interdigitation of the polymethylmethacrylate (PMMA) bone cement with the surface texture and the apposing bone. This femoral component features cast-in pegs to help in femoral component placement, and to provide rotational stability. ### PROLIXUS™ Cruciate Retaining (CR) Tibial Insert The Cruciate Retaining (CR) Tibial Insert is neutral in configuration, and is available in six proportional sizes (sizes 1 to 6) and varying thicknesses (10mm, 12mm,14mm, 16mm, 18mm and 20 mm). The insert is fabricated from ultra high molecular weight polyethylene(medical grade PUR 1020 UHMPE) .The tibial insert is designed to accommodate the posterior cruciate ligament if it is present. There is a relief on the {5}------------------------------------------------ anterior aspect of the tibial insert to accommodate the patellar tendon and patellar fat pad. # PROLIXUS™ Tibial base plate Stem tibial baseplate components (tibial baseplate) are made from Ti-The angled 6Al-4V titanium alloy. Tibial baseplates are available in 6 sizes (1 to 6). # PROLIXUS™ | Patellar components patellar component is made from ultra high molecular weight The polyethylene(medical grade PUR 1020 UHMPE). The patella is available in five diameters, 26mm, 29mm, 32mm, 35mm and 38mm, which permit optimal bone coverage and surgical options. # 5.

Knee geometry and surfaces ### Femoral component- In accordance to ISO 7207-2 the articulating surface roughness has been described by the parameters Ra, Rz and Rt for five femoral components. Related to the demands of ISO 7207-1 the geometric dimensions were determined for the same five femoral components ### Surface finish: A total mean Ra value of 0.013 µm (Std. Dev. 0.001 µm) was measured. A total mean Rz value of 0.194 um (Std.Dev. 0.279 um) was measured. A total mean Rt value of 0.127 µm (Std.Dev. 0.003 µm) was measured. Referenced to the surface finish requirements according to ISO 7207-2 no femoral component exceeded a roughness value Ra grated than 0.1 µm. ### Tibia base component- The purpose of this analysis was to determine the geometric dimensions of five tibial trays according to ISO 7207-1 and to determine the surface roughness at the femoral surface of the tibial trays. ### Surface finish: A total mean Ra value of 0.62 um (Std. Dev. 0.078 um) was measured. A total mean Rz value of 3.37 um (Std.Dev. 0.410 um) was measured. A total mean Rt value of 5.05 µm (Std.Dev. 0.954 µm) was measured. ### Tibia insert component- The purpose of this analysis was to determine the minimum thickness of five unconstrained bi compartmental (fixed bearing) tibial inserts and to determine the surface roughness at the load bearing side of the tibial inserts. Surface finish: An overall mean Ra value of 0.212 um (Std. Dev. 0.079 um) was measured. An overall mean Rz value of 1.084 um (Std. Dev. 0.391 um) was measured. An overall mean Rt value of 1.776 um (Std. Dev. 0.598 um) was measured. Referenced to the surface finish requirements according to ISO 7207-2 , no insert exceeded a roughness value Ra greater than 2.0 µm. The surface roughness values determined for each insert at the different locations are shown {9}------------------------------------------------ ### Minimum thickness: A total mean lateral thickness of 6.77 mm (Std. Dev. 0.05 mm) and a total mean medial thickness of 6.77 (Std. Dev. 0.05 mm) have been determined. ISO 21536: 2007 (Non-active surgical implants - Joint replacement implants - Specific requirements for knee-joint replacement implants) requires a minimum thickness in the load bearing area of 6 mm for components having a tibial tray. None of the inserts analyzed showed a minimum thickness smaller than 6 mm . ### Patella component- In accordance to ISO 7207-2 the interested articulating surface roughness has been determined by the parameters Ra, Rz and Rt for six patella components. Related to the demands of ISO 7207-1 the minimum thicknesses of have been determined for the same six patella components listed above. ### Surface finish: An overall mean Ra value of 0.79 µm (Std. Dev. 0.20 µm), an overall mean Rz value of 3.20 µm (Std.Dev. 0.65 µm) and an overall mean Rt value of 4.18 µm (Std. Dev. 0.98 um) were determined.Referenced to the surface finish requirements according to ISO 7207-2 (see section 5.1) no patella component exceeded a roughness value Ra greater than 2.0 um. The surface roughness values determined for each patella component at the different locations are shown . ### Minimum thickness and width dimensions: An overall mean thickness of 8.01 mm (Std. Dev. 0.05 mm) and an overall mean width of 25.98 (Std.Dev. 0.02 mm) have been determined. ### 7. Range of motion CAD analysis A CAD analysis of the TKR Otis Size 1 system has been performed using IGES files .A total of four different rotations/translations have been investigated: Flexion/extension, rotation,medial-lateral and anterior posterior translation. In addition, the medial as well as the lateral contact point have been investigated for seven different flexion angles. All motions observed correspond to typical findings as expected for fixed type bearings. The sliding/rolling analysis supports the common theory of mixed sliding/rolling articulations for this type of bearing. Varus/valgus rotation and proximal/distal translation are not constrained by this type of implant and have not been simulated. Due to the low degree of constraint, different types of articulating motions are expected in-vivo depending on the soft tissue balance, the muscular status as well as the daily living activities of the patient. The analysis of the kinematics presented herein therefore should be regarded as average positioning within an array of possible motions. # 8. Pyrogen and Endotoxins Testing : Bacterial endotoxins test (BET), also known as the Limulus amebocyte lysate (LAL) test) : As a result of endotoxin test validation for thThe PROLIXUS™ Cruciate Retaini ng (CR) Total Knee System, it was confirmed that the endotoxin test reagent (PTS {10}------------------------------------------------ cartridge) and the laboratory environment were suitable for endotoxin test by the initial qualification test. Inhibition/enhancement Tests conclude that the product is suitable for endotoxin testing using both PTS readers and PTS cartridge, meeting both endotoxin standards and established criteria for testing. {11}------------------------------------------------ # 7.
