The Orthonika TMR Implant
Uniquely restoring native meniscus function
with bio-inspired design and materials.
A Comprehensive Solution
Engineered to replicate the native meniscus, the Orthonika TMR implant combines advanced design and innovative materials.
Available in a full range of sizes, it delivers true anatomical replacement tailored to every patient.
1
Continuous circumferential fibre reinforcement
2
Conforming, low friction articulating body peripherally fixed to the joint capsule
3
Strong, validated and well-established fixation to bone
4
Anatomical root location preserving joint tissues
Precision Surgery Enhanced Recovery
Bespoke, minimally invasive surgical technique positions the Orthonika TMR implant exactly where it needs to be.
Step 1
Precise ‘keyhole’ removal of the injured meniscus.
Step 2
Patient specific implant sizing and corresponding drilling of fixation bone tunnels.
Step 3
Implantation of the Orthonika TMR implant with comprehensive range of motion and stability verification.
Key TMR Benefits
Arthroscopic Surgical Procedure
Minimally-invasive arthroscopic technique spares ligaments and cartilage with minimal infection risk, swelling, and external scars.
Physiological Accurate Design
Anatomically accurate implant geometry, implanted with a precise positioning technique to reliably simulate healthy meniscus function.
Extensively Tested and Validated
Interference screw fixation and biocompatible synthetic materials allow immediate post-operative weight bearing, enabling faster rehabilitation.
Globally Protected Design & Innovation
The highly disruptive, proprietary TMR implant and fixation design is backed by multiple patent families in the USA, Europe, and UK.
Total Meniscus Replacement vs Total Knee Arthroplasty The Orthonika TMR implant only replaces the injured meniscus tissue, avoiding premature Total Knee Arthroplasty (TKA)
