01 — Design features
Secure, strong and biocompatible graft fixation
Seven design decisions behind the button — dimensions, material, loop and fit.
01
Precision-engineered dimensions
Stub diameter 7.5 mm for optimal seating in the bone tunnel; disc head diameter 16 mm ensures effective load distribution.
02
Safe and biocompatible
PEEK is an MRI-safe and chemically inert material that minimizes reactions.
03
Loop construction
UHMWPE fibre size 3, offering high strength and durability.
04
Optimized graft preservation
A single tendon suffices for a short and thick graft.
05
High pull-out strength
1300N+ strength for long-term stability.
06
Reliable fixation
The stub secures the button inside the tunnel; the head rests flush against the tibial cortex with minimal protrusion above the bone surface.
07
Universal fit and ease of use
One-size-fits-all design simplifies inventory management and suits surgical needs.
