SOLVEX® Hinged Knee (EN) | Solvex Medical Devices

SOLVEX® Hinged Knee Prosthesis System

The SOLVEX® Hinged Knee Prosthesis System is engineered to provide enhanced mechanical stability and mobility for patients with severe knee conditions, including ligamentous insufficiency, extensive bone loss, or gross joint instability. Through its robust hinged articulation, this system offers a dependable solution for complex primary or revision total knee arthroplasty.

Key Components

Femoral Component

Fabricated from high-performance Cobalt-Chromium-Molybdenum (CoCrMo) alloy, ensuring superior strength and wear resistance.
Designed to articulate seamlessly with the tibial component, it mimics the distal femur’s natural geometry while housing the hinge mechanism.
Equipped with an extended intramedullary stem for secure fixation within the femoral canal, particularly in cases of compromised bone stock.

Tibial Component

Composed of a high-strength metal alloy baseplate offering a stable platform for weight transfer and implant anchorage.
Available with various modular stem extensions to accommodate differing levels of bone deficiency and achieve optimal metaphyseal and diaphyseal fixation.

Tibial Insert

Manufactured from ultra-high-molecular-weight polyethylene (UHMWPE), the insert provides a low-friction articulating interface between the femoral and tibial components.
Engineered to sustain repetitive loading while resisting wear and deformation.

Hinge Mechanism

A mechanically linked hinge connects the femoral and tibial components, maintaining axial alignment and preventing dislocation in the absence of functional collateral or cruciate ligaments.
The hinge ensures controlled flexion and extension while resisting pathological varus, valgus, and rotational forces.

Rotating Platform

Integrated into the tibial assembly, the rotating platform permits controlled axial rotation during gait cycles.
This feature reduces torsional loads on the implant–bone interface, thereby enhancing the prosthesis's mechanical longevity and reducing the risk of aseptic loosening.

System Highlights

🔩 Secure Hinge Architecture
Engineered for knees with compromised soft tissue support, the hinged mechanism delivers consistent joint stability under high-demand conditions.

🧩 Comprehensive Modularity
A wide range of femoral and tibial stem lengths, augmentation options, and polyethylene inserts enables intraoperative customization to match patient-specific anatomical and biomechanical requirements.

🛡️ Enhanced Structural Support
Ideal for cases with severe bone loss or previous implant failure, the system ensures reliable fixation and resistance to micromotion.

🦾 Advanced Biomaterials
Biocompatible CoCrMo alloys and UHMWPE polymers provide a robust, wear-resistant construct capable of withstanding long-term physiological stress.
