The goal of the Ruby Joint Stabilization System (Ruby)* is to provide surgeons with the most biocompatible, strongest, abrasion resistant implant that is stable at its interface to the bone, straightforward in its surgical application and kinematically compatible with canine stifle range of movement.
The Ruby system is comprised of a bone anchor screw with a ruby eyelet at the suture exit and a grooved conical pin to affix a closed loop of suture to the anchor. Two anchors, preassembled with suture in set lengths, are inserted into the tibia and femur, leaving a small gap between the suture loops. The assembly is completed by hooking the loops together with a polished titanium link. The loops are trapped within the link by a snap-in PEEK link lock.
Ruby joint stabilization circumvents the need to tie knots or crimp, bringing the ultimate strength of the construct closer to the theoretical limit of the materials. Static tensile strength exceeds 1,000 N.
To address the infection, bone erosion, breakage and loosening complications related to bone tunneling, the Ruby system attaches the suture to the bone using a titanium aluminium niobium (TAN) bone anchor screw and mono-crystalline ceramic ruby eyelet. TAN is optimal for osseointegration and the ruby eyelet provides an ideal surface for the sweeping movement of the unbraided and uncoated ultra-high molecular weight polyethylene (UHMWPE) suture loops.
This KYON project began in 2007, utilized an iterative implant design process, clinical refinement and several in vitro studies before the first clinical case in 2015. Ruby is in limited clinical release and meeting the expectations of the early adopters.
The Ruby system is currently in controlled clinical release. We require all users to attend a KYON course prior to purchase of the equipment.
