SOLVEX® Total Knee Arthroplasty System

The SOLVEX® Total Knee Arthroplasty (TKA) system is a state-of-the-art prosthetic solution designed to restore normal joint mechanics and relieve pain in patients suffering from end-stage knee pathologies such as osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis. Engineered for long-term durability and optimal biomechanics, the system incorporates four primary components:

Component Overview

1. Femoral Component
Manufactured from Cobalt-Chromium-Molybdenum (CoCrMo) alloy, the femoral component features an anatomically contoured design to replicate the distal femur’s natural curvature. Its polished articulation surface minimizes friction, supports smooth motion, and preserves physiological kinematics during flexion and extension.

2. Tibial Component
This robust metallic baseplate anchors securely into the proximal tibia. Engineered for high mechanical stability, it evenly transmits axial loads and resists micromotion. Hydroxyapatite surface treatment is applied to promote osteointegration, enhancing biological fixation.

3. Articular Insert
Situated between the femoral and tibial components, the articular insert is fabricated from ultra-high-molecular-weight polyethylene (UHMWPE). It functions as the primary bearing surface, offering excellent wear resistance, low friction, and effective shock absorption during gait and weight-bearing activities.

4. Patellar Component
Made of UHMWPE, the patellar component replaces the native patella and maintains patellofemoral congruity. Its design enables smooth articulation with the femoral groove, reducing anterior knee pain and supporting efficient force transmission through the extensor mechanism.

Key Advantages

🦴 Anatomically-Informed Design
Components are shaped to reflect natural knee anatomy, ensuring proper alignment, kinematic balance, and soft tissue compatibility.

⚖️ Optimized Load Distribution
Strategic geometry and high-strength interfaces distribute mechanical loads uniformly, reducing stress concentrations and risk of implant loosening.

🛡️ Mechanical Stability
The multi-component construct enhances joint stability and decreases the likelihood of dislocation or mechanical failure under functional loads.

🔬 Advanced Biomaterials
The use of CoCrMo alloys and high-density polyethylene ensures high biocompatibility, corrosion resistance, and wear longevity.

🧬 Bioactive Surface Technology
Hydroxyapatite coatings on bone-contact surfaces promote direct bone apposition, favoring stable, long-term osteointegration without the need for cement in certain cases.
