Technical Advantages

The Knee Joint Femoral Component features a highly polished CoCrMo articulating surface with sub-micron roughness (Ra < 0.02 μm), which lowers frictional forces and suppresses generation of wear particles. The substrate material is low-carbon vacuum-cast cobalt-chromium conforming to ASTM F1537, engineered to minimize carbide precipitation and intergranular corrosion. Nitrogen ion implantation and advanced passivation further reduce ion leaching in inflammatory biological environments.

The Knee Joint Femoral Component is designed to support intraoperative constraint modulation across CR, PS, and CCK insert configurations without requiring changes in femoral box geometry. Constraint compatibility is achieved through a standardized intercondylar box and anterior flange architecture, ensuring smooth component interchangeability. This design enables surgeons to respond to varying ligament conditions without compromising component alignment or stability.

Industry Applications

Total Knee Arthroplasty (TKA)

Used as the load-bearing articulating surface in TKA systems to restore biomechanical alignment and femorotibial kinematics effectively.

Revision Knee Replacement Procedures

Essential for complex revisions requiring femoral reconstruction due to bone loss, implant loosening, or periprosthetic joint infection.

Trauma-Based Femoral Reconstruction

Deployed in post-traumatic reconstructions involving distal femoral comminution or deformity correction requiring precise articulating geometry.

Osteoarthritis-Induced Degeneration Cases

Functions as the articulating femoral surface in patients with severe cartilage loss and subchondral bone sclerosis due to osteoarthritis.

Post-Oncologic Resection Reconstructions

Supports structural load transmission following distal femoral tumor resection with modular stem compatibility and stable fixation design.

Rheumatoid Arthritis Joint Destruction

Used in end-stage inflammatory joint disease to replace destructed femoral condyles and re-establish sagittal and coronal joint mechanics.

Osseointegration-Driven Fixation Mechanisms

The cementless variant of the Knee Joint Femoral Component incorporates a dual-surface fixation strategy using sintered bead porosity layered with titanium plasma spray, promoting both macro-mechanical interlock and cellular-level osseointegration. Pore sizes and interconnectivity exceed 150 µm, optimized for osteoblast migration and bone ingrowth. Cemented configurations utilize laser-textured surfaces for enhanced interdigitation and fatigue resistance of the cement-implant interface.

The Knee Joint Femoral Component is engineered to maintain uniform tibiofemoral contact pressure through asymmetric condylar contours and optimized sagittal curvature. Finite element analysis demonstrates reduced peak contact stresses during stair ascent and descent cycles. Material stiffness is controlled to reduce proximal stress shielding, particularly in low-density femurs where cortical resorption is a risk.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure dimensional tolerance in Knee Joint Femoral Components during CNC machining?

Frigate uses precision multi-axis CNC machining with real-time process monitoring to maintain tight tolerances on femoral component geometry. Specialized jigs and fixtures minimize deflection during milling and drilling operations. Dimensional inspection is conducted with CMMs using CAD models as reference. This ensures the femoral component matches implant design specifications consistently.

What surface roughness level does Frigate achieve on Knee Joint Femoral Components before coating?

Frigate machines femoral components to a surface roughness value typically between Ra 0.2 µm and Ra 0.8 µm. This roughness level supports effective adhesion of titanium or hydroxyapatite coatings. Controlled polishing and micro-finishing are done using automated systems to ensure repeatability. Final roughness is verified using profilometers and documented per implant standards.

How does Frigate handle metallurgical integrity during Knee Joint Femoral Component heat treatment?

Frigate uses vacuum heat treatment to avoid oxidation and preserve the alloy’s structural integrity. Controlled cooling cycles prevent distortion and maintain hardness levels required for femoral load-bearing. Post-treatment hardness and grain structure are validated with Rockwell testing and metallography. This ensures the femoral component retains its fatigue resistance and wear strength.

How does Frigate validate coating thickness on Knee Joint Femoral Components?

Coating thickness is measured using X-ray fluorescence (XRF) or eddy current testing methods. Frigate calibrates these systems against certified reference standards to maintain traceability. Each femoral component is inspected for uniform coating coverage across all articulating and fixation zones. This guarantees optimal biocompatibility and implant fixation performance.

What traceability systems does Frigate implement for Knee Joint Femoral Component production batches?

Frigate assigns a unique identifier to every Knee Joint Femoral Component batch through laser marking and digital records. All machining, inspection, and material certificates are logged into a controlled traceability database. This system complies with ISO 13485 and FDA 21 CFR Part 820 documentation standards. Full production history can be retrieved for any femoral component delivered.
