The Clinical Opportunity

Over the past 40 years, hip and knee arthroplasty has continually been refined.  Patients now expect fast recovery, peak performance and minimal surgical trauma.  Clinical results are well documented in the literature. These procedures have become safe, predictable and for the most part routine.  This “refinement” process has played out through incremental advancements in design, instrumentation and / or surgical technique.  Nonetheless, unmet needs remain. 

One characteristic of typical hip and knee arthroplasty surgical procedures that has remained unchanged is in preparing the articular surfaces of the joint independent of one another, independent of soft tissue structures, and most importantly preparing each side relative to its own bony landmarks.  The rationale is to reconstruct the articular surface on each side of the joint independently, then balance the soft tissues to accommodate the reconstruction.  We believe this independent preparation is a contributing factor in current hip and knee replacement systems coming up short in providing the patient a natural feeling joint, natural motion and confidence.  ART addresses this unmet need by developing products based on our proprietary Tissue Guided Surgery technology, TGS^® Technology.

The Tissue Guided Solution

Tissue Guided Surgery levels the playing field.  We believe TGS^® enabled total joint replacement will provide accurate, patient specific, joint replacement in the hands of the majority of surgeons.  TGS^® is a platform technology developed by ART in which the motion of the knee or hip joint is used intraoperatively to guide bone preparation and implant placement to optimize motion and function (i.e.  kinematics) for a specific patient. 

The full potential of TGS^® is realized through the combination of this technology with novel implant systems developed to provide ease of placement and the adaptability to match the patient specific nature of soft tissue balancing.
