This prosthesis may be used for the following conditions, as appropriate: • Non-inflammatory degenerative joint disease, including osteoarthritis and avascular necrosis; • Rheumatoid arthritis; • Correction of functional deformity; • Revision procedures where other treatments or devices have failed; The porous coated femoral component may be used cemented or uncemented (biological fixation). All other femoral, tibial baseplate and patellar components are indicated for cemented use only. The Apex Knee™ Modular Tibia System Tibial Augment are intended to be bolted to the Tibia baseplate and cemented to the prepared tibia. ## Device Story Apex PS Knee System is a semi-constrained total knee replacement prosthesis; includes posterior stabilized (PS) femur component with box, PS tibial insert, and tibial baseplate. Designed for primary or revision total knee arthroplasty. Femur components available in cemented or uncemented versions; other components cemented only. PS insert features cam-and-post mechanism to control kinematics and provide stability. Used by orthopedic surgeons in clinical/hospital settings. Provides range of motion up to 140 degrees. Benefits include restoration of joint function, correction of deformity, and relief from degenerative joint disease symptoms. Output is physical joint replacement; surgeon uses intraoperative assessment to select appropriate UHMWPE insert thickness for soft tissue balance. ## Clinical Evidence No clinical studies were performed. Substantial equivalence is based on non-clinical bench testing, including range of motion, contact area, constraint (ASTM F1223-03), post strength, patello-femoral contact, wear testing (ISO 14243-2/3), and surface finish analysis. ## Technological Characteristics Semi-constrained knee prosthesis; materials include metal (CoCr) and polymer (UHMWPE). Features posterior stabilized cam-and-post design. Standards: ASTM F2083-08 (Total Knee Prosthesis), ASTM F1223-03 (Constraint), ISO 14243 (Wear), ISO 7207-2, ISO 21534, ISO 21536. Femoral components available with porous coating for biological fixation. Modular tibial augments. No software or electronic components. ## 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 - Apex Knee™ System ([K060192](/device/K060192.md)) - Apex Knee™ System Porous Coated Femoral Components ([K073602](/device/K073602.md)) - Darwin Knee System ([K950010](/device/K950010.md)) - The Natural-Knee® II knee system ([K936159](/device/K936159.md)) ## Reference Devices - DePuy P.F.C.

incorporating a proportionally sized box. The Femur Component has the same
bone cuts as the Apex Knee™ System (K060192) with the addition of a cut for the
Femur Component box. Femur Components will be available in both cemented
and uncemented versions. Size ranges, high flex, and all other design features of
the Apex Knee System are retained. The PS Insert has a medio-lateral constraint
and utilizes the Apex Knee System Tibial Baseplate. For each PS Insert, a range of
UHMWPE thicknesses are available to aid in obtaining the proper soft tissue
balance across the knee joint. | | | | Indications for Use | The Apex Knee™ System is intended for use as a primary or revision total knee
replacement. This prosthesis may be used for the following conditions, as
appropriate:
• Non-inflammatory degenerative joint disease, including osteoarthritis and
avascular necrosis;
• Rheumatoid arthritis;
• Correction of functional deformity;
• Revision procedures where other treatments or devices have failed;

The porous coated femoral component may be used cemented or uncemented
(biological fixation). All other femoral, tibial baseplate and patellar components
are indicated for cemented use only.
The Apex Knee™ Modular Tibia System Tibial Augment are intended to be bolted
to the Tibia baseplate and cemented to the prepared tibia. | | | {1}------------------------------------------------ K102578 #2/4 ## Predicate Device Comparison | | | Device Comparison | | | | |--------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------|--| | | APEX PS TKA
