The subject stems are intended to be cemented and have a glass-beaded body, medial collar, proximal shoulder and neck region with a surface roughness identical to the legally marketed modular PROFEMUR® GLADIATOR® Cemented Stem (K111910, SE 10/14/2011) with PROFEMUR® Cobalt Chrome Modular Necks (K091423. SE 08/25/2009; K100866. SE 04/28/2010). The subject stems possess a proximal medial collar designed to assist rotational stability and offer protection against subsidence, identical to the cleared predicate PROFEMUR® GLADIATOR® Cemented Stem (K111910, SE 10/14/2011) with PROFEMUR® Cobalt Chrome Modular Necks (K091423, SE 08/25/2009; K100866, SE 04/28/2010). The trunnion is a MicroPort 12/14 SLT taper, with an as-machined geometry to form a taper lock with a mating femoral head implant. The trunnion is identical to the MicroPort femoral stem tapers of the predicate and reference devices. The subject stems possess an oval impaction feature on the proximal shoulder for proper femoral stem insertion into the femoral canal, identical to the cleared reference PROFEMUR® GLADIATOR® Thin HA Classic Stem w/ Collar (K200007, SE 04/25/2020). #### Materials The subject PROFEMUR® GLADIATOR® Cemented Classic Stems are manufactured from forged cobalt chromium alloy (ASTM F799). #### Geometry and Dimensions The PROFEMUR® GLADIATOR® Cemented Classic Stems were designed to accommodate a wide range of patient anatomy and to provide an optimized fit to adequately restore the biomechanics of the respective hip (including restoration of the natural leg length and head center offset). The subject PROFEMUR® GLADIATOR® Cemented Classic Stems are offered in sizes 4, 6, 8, 10, and 12 with the stem length ranging from 125mm to 170mm, identical to the cleared reference PROFEMUR® GLADIATOR® Cemented Stems (K111910, SE 10/14/2011). The subject classic stem possesses two different neck options: standard (with a CCD neck angle of 135°) and extended/Varus 8° (with a CCD angle of 127°). #### Intended Use: PROFEMUR® GLADIATOR® Cemented Classic Stems are intended for use in total hip arthroplasty for reduction or relief of pain and/or improved hip function in skeletally mature patients. #### Indications for Use: The subject device is indicated for the following conditions: {5}------------------------------------------------ Image /page/5/Picture/0 description: The image contains the logo for MicroPort Orthopedics.

The logo consists of a blue square with rounded corners, inside of which is a red star-like shape. To the right of the square is the text "MicroPort" in a larger, bold, blue font, and below that is "Orthopedics" in a smaller, blue font. Below "Orthopedics" is the text "Full Function, Faster" in a smaller, blue font. The mechanical testing and engineering analyses performed that are applicable to the subject PROFEMUR® GLADIATOR® Cemented Classic Stems include: - 1. Proximal Fatigue Strength Testing and Analysis - 2. Distal Fatigue Strength Testing and Analysis - 3. Range of Motion (ROM) Testing and Analysis - 4. Magnetic Resonance Imaging (MRI) Safety Analysis The data demonstrates that the subject PROFEMUR® GLADIATOR® Cemented Classic Stems are substantially equivalent to the legally marketed predicate, PROFEMUR® GLADIATOR® Cemented Stem (K111910, SE 10/14/2011) with PROFEMUR® Cobalt Chrome Modular Necks (K091423, SE 08/25/2009; K100866. SE 04/28/2010). Having met all acceptance criteria for mechanical testing performed on worstcase constructs, the subject PROFEMUR® GLADIATOR® Cemented Classic Stems do not introduce new or modified risks for safety and effectiveness compared to the predicate or other reference MicroPort Hip Systems and acetabular components which utilize comparable test methods and acceptance criteria. #### Conclusion: Based on the design features, the use of established well-known materials, feature comparisons, indications for use, principle of operations, and results of the mechanical testing and engineering analyses, the subject PROFEMUR® GLADIATOR® Cemented Classic Stems have shown to be substantially equivalent to the legally marketed predicate devices cited in this premarket notification.
