Biomechanical Engineering of the Primary Total Knee System

Femoral Component Design

Manufactured from premium medical-grade Cobalt-Chromium-Molybdenum (CoCrMo) alloy, our femoral components feature high-flexion geometry to promote deep knee bending up to 135°. The articular surface undergoes multi-stage polishing to achieve a mirror finish (surface roughness Ra < 0.05μm), reducing friction and maximizing the life expectancy of the polyethylene joint insert.

Tibial Tray & Insert Stability

We leverage Titanium Alloy (Ti6Al4V) for the tibial tray to ensure excellent biocompatibility and high strength while avoiding the stiffness that leads to stress shielding. The articulating insert is machined from Ultra-High-Molecular-Weight Polyethylene (UHMWPE) or highly cross-linked polyethylene (XLPE), ensuring low wear rates and long-term durability in high-activity patients.

PS vs CR Configurations

Understanding diverse surgical requirements, we provide both Posterior-Stabilized (PS) and Cruciate-Retaining (CR) systems. Our PS design features a optimized cam-post mechanism that prevents subluxation and restores natural kinematics, while our CR design preserves the patient's posterior cruciate ligament (PCL) for a more organic joint motion feel.

Vertical Integration: From Raw Material to Precision Implant

Our vertical integration ensures complete traceability. From sourcing certified bar stock to mechanical fatigue testing, we control every parameter of the orthopaedic device value chain.

China's Supply Chain Advantages for Orthopedic Systems

Industrial Clustering

Cost Efficiency & Integration

By leveraging China's dense medical manufacturing corridors, Medisplint integrates tooling, raw material refinement, surface polishing, and packaging under one supply ecosystem. This reduces waste and yields a 30-40% savings compared to Western fabricators, without compromising raw material specifications.

Material Access

Premium Medical Alloys

Our supply chain works directly with certified suppliers of ASTM F136 implant-grade Titanium and ASTM F75 Cobalt-Chromium-Molybdenum. This ensures consistent microstructure properties and avoids potential degradation issues, guaranteeing long-term clinical safety.

Agility & Customization

85+ Engineer Customization

We translate raw clinical requests into finished implants rapidly. With 85 design engineers, our team handles modifications for regional anatomical features (e.g., matching narrower femoral dimensions for Asian or Latin American cohorts) with extreme speed.

Localization Support, Regulatory Compliance, & Global Sourcing

Ensuring Legal Readiness and Smooth Custom Registrations

Distributing Class III medical devices demands strict compliance. Medisplint supports orthopedic importers by preparing comprehensive technical dossiers (CTD), biocompatibility reports (ISO 10993), and clinical evaluation documents. We offer complete assistance to streamline approvals with regional health bodies (such as EMA, ANVISA, COFEPRIS, and NMPA).

Our products feature fully traceable UDI (Unique Device Identification) barcode engraving to meet strict track-and-trace requirements from modern hospitals and national implant registries.

Comprehensive Logistics Options

  • Sterile Barrier System (SBS): Double sterile pouch packaging with EO (Ethylene Oxide) or Gamma sterilization options.
  • Non-Sterile Configuration: For local distributors or hospitals that prefer autoclaving on-site or using local cleanroom sterilizing partners.
  • Custom Surgical Kits: Integration of specialized toolsets (like trial components, femoral cutting blocks, and alignment guides) matching local surgical preferences.

Sourcing Roadmap for Global Distributors

Medisplint simplifies procurement with a structured process designed for procurement managers and medical device distributors:

  1. Technical Consult: Alignment on anatomical profiles (CR vs. PS knee, sizing, instrument compatibility).
  2. Quality Dossier Delivery: Submission of CE, ISO 13485, and material certificates.
  3. Sample Evaluation: Delivery of non-sterile trial implants for surgical review and mechanical validation.
  4. Bulk Manufacture & Packing: Class-10,000 cleanroom assembly, laser marking, and double-sterilized barrier sealing.
  5. Logistics & Customs Cleared: Air or sea shipping with complete customs declaration paperwork.

Clinical Applicability & Regional Adaptation

Human Joint Reconstruction Centers

Designed for public hospitals and private orthopaedic centers, our Primary Total Knee System offers reliable clinical performance. With streamlined instrumentation, surgeons can minimize operation times, lower infection risks, and speed up post-operative recovery.

Veterinary Joint Replacements & Specialty Implants

Orthopedic requirements extend to veterinary health. Medisplint leverages its precision machining platforms to produce veterinary surgical power tools, TPLO plates, and small joint implants. These help veterinary surgeons treat severe osteoarthritis and ligament ruptures in large canine breeds.

Frequently Asked Sourcing Questions

What materials are used in the Medisplint Primary Total Knee System? +
Our femoral components are cast and machined from medical-grade Cobalt-Chromium-Molybdenum (CoCrMo) alloy, compliant with ASTM F75. Tibial trays are made of high-tensile Titanium alloy (Ti6Al4V, ASTM F136), and our bearing inserts are manufactured from Ultra-High-Molecular-Weight Polyethylene (UHMWPE) or highly cross-linked polyethylene (XLPE) to minimize wear.
Are your manufacturing processes compliant with CE and ISO standards? +
Yes, Medisplint operates under a comprehensive ISO 13485 Quality Management System. Our key joint and trauma product lines are CE marked, complying with EU medical device directives. Every batch undergoes strict quality control (IPQC & FQC) with full traceability.
Can you support OEM/ODM requests and custom sizing? +
Absolutely. With over 85 engineers in our R&D team, we can customize implants to meet regional anatomical preferences, modify instrumentation layouts, or provide private labeling (OEM) and custom design solutions (ODM).
What is your typical production lead time for bulk orders? +
Standard implants in stock can ship within 7–15 days. For customized OEM components or large container orders, production typically takes 30–45 days, depending on geometry complexity and sterilization requirements.
How do you guarantee the fatigue and wear life of your joint implants? +
Every implant design undergoes rigorous in-house fatigue testing simulating millions of walking cycles (ISO 14879 standard). We verify material hardness with Rockwell/Vickers testers and measure dimensional accuracy down to the micron level using optical 2D instruments and coordinate measuring machines (CMM).
