Tibial Insert

The Tibial Liner is a key friction interface component of the total knee arthroplasty system, fitting between the femoral component and tibial tray. It provides cushioning and friction reduction during joint movement, while maintaining knee stability and mobility. As a core component connecting the prosthesis to the body's anatomical structure, it directly impacts post-operative joint flexibility and long-term prosthesis durability. It is indicated for patients with severe knee dysfunction caused by osteoarthritis, rheumatoid arthritis, knee trauma, etc.

1. Multiple Thickness Specifications for Precise Joint Gap Adaptation

Thicknesses range from 9mm to 18mm at 1mm intervals. The rich size options enable surgeons to precisely balance the knee's flexion-extension gap during surgery, improving surgical adaptation accuracy and avoiding issues of overly tight or loose joints.

2. 5° Anatomical Posterior Tilt Angle, Matching Human Anatomy

Following the natural anatomical characteristics of the proximal tibia, the 5° posterior tilt design not only avoids errors in posterior tilt osteotomy during surgery but also enhances the fit between the prosthesis and the bone bed, reducing the risk of stress mismatch.

3. Beveled Posterior Edge for Expanded Mobility Range

Optimized via a beveled posterior edge, the liner supports a knee joint mobility range of up to 155°, significantly improving post-operative flexion-extension flexibility. This brings the joint's mobility closer to that of a normal knee, helping patients restore daily activity functions.

4. MB-Type Modular Compatibility, Covering Diverse Cases

The MB-type tibial liner can be freely paired with MB-type tibial trays of different specifications, while being compatible with both CR and PS femoral components. Flexible modular combinations adapt to patients' personalized knee anatomical parameters, covering complex clinical scenarios.

1. More Precise Intraoperative Adaptation

The 1mm-interval multi-thickness design allows surgeons to finely adjust the joint gap based on the patient's actual knee conditions, achieving optimal joint balance and improving post-operative joint stability and comfort.

2. Higher Anatomical Fit

The 5° posterior tilt angle matches the natural anatomical structure of the proximal tibia, reducing stress concentration between the prosthesis and bone bed, lowering the risk of post-operative prosthesis loosening and wear, and extending prosthesis service life.

3. More Flexible Post-Operative Mobility

The 155° wide mobility range design breaks the movement limitations of traditional prostheses, helping patients restore near-normal knee flexion-extension functions post-operatively (e.g., easily performing squats, climbing stairs) and improving quality of life.

4. Flexible Modularity for Broad Adaptation

The MB-type's free modular design is compatible with different femoral components and tibial trays, adapting to patients with varying anatomical parameters and joint gap needs, and covering more complex clinical cases.

Primary Total Knee Arthroplasty: For patients with primary knee lesions (e.g., osteoarthritis, rheumatoid arthritis);

Personalized Knee Replacement Needs: Through multi-thickness options, adapting to patients with different joint gaps and anatomical parameters;

Patients with High Mobility Demands: The 155° wide mobility range design meets the needs of patients (e.g., younger, more active individuals) who require high joint flexibility post-operatively.
