Femoral Stem System
Wide range of primary and revision femoral stems including cementless, cemented, and modular options for all clinical scenarios.
The AK Medical Femoral Stem System comprises 12 products across stem components. Regulatory clearances held across the range: NMPA (China, formerly CFDA); CE Mark (European Union). Clearance status is product-specific — see each product page.
Products
AK-ML-TP Femoral Stem
Tapered Wedge design provides firm mediolateral stability. Available in 127° and 132° neck shaft angles with 24 sizes.
SpecificationsAK-ML-II-TP Femoral Stem (Short Stem)
Short stem design preserves large trochanter bone mass. Particularly suited for Direct Anterior Approach (DAA). Prevents thigh pain.
SpecificationsAK-ML-TH Femoral Stem
Tapered Wedge design with dual Titanium Plasma Spray + HA Coating. Available in 127° and 132° neck shaft angles.
SpecificationsAK-MP-TP Femoral Stem
Classic tapered stem philosophy with polished bullet-shape distal tip. 3-degree biplanar taper. Medially rounded, laterally flared proximal geometry.
SpecificationsAK-CL Femoral Stem
Double Coated with 50μm pure titanium and 150μm HA coating. Low-profile lateral shoulder for anterior approach. Double taper trapezoidal design.
SpecificationsCPII Cemented Femoral Stem
High Nitrogen Stainless Steel polished tapered design. Collarless double taper. Optimizes compression forces in bone cement mantle.
SpecificationsACP / ACP Long Cemented Femoral Stem
Double taper wedge cemented stem. Polished tapered design transfers compression forces. Collarless design simplifies leg length adjustment.
SpecificationsAK-SR Femoral Stem
Modular revision stem with different triangle sizes. Step design converts shear forces into compressive loads. Flutes prevent thigh pain. Distal diameter from 6mm.
SpecificationsAK-SL-Cone Femoral Stem
For difficult bone conditions. Conical shape with 5° cone angle and 8 sharp longitudinal ribs. Free setting of antetorsion. CCD-angle 125° and 135°.
SpecificationsAK-SL Femoral Stem
For uncemented fixation in femoral revision surgery. 2° tapered stem with 8 longitudinal ribs. Guaranteed distal fixation using Wagner principle.
SpecificationsAK-MR Femoral Stem
Modular proximal and distal components for wide patient anatomy variance. Sharply splined and tapered distal stem for secure fixation. Favorable bone remodeling.
SpecificationsAK-ABM Femoral Stem
Modular revision system with proximal cone stem and distal taper/cylindrical stem options. Long-term osseointegration via plasma-sprayed titanium microporous coating.
