New Knee Research Finds Exactech Technologies Improve Patient Outcomes

ExactechGPS Guided Knee Surgery

Exactech, a developer and producer of innovative implants, instrumentation, and smart technologies for joint replacement surgery, announced new research that reports surgeons using ExactechGPS® guided personalized surgery and its Newton® ligament-driven balancing technique experience clinically significant improvements on postoperative Knee Society Knee and Function scores when compared to traditional navigated gap balancing methods, according to a recent study published in the Journal of Arthroplasty.

“Optimizing soft tissue balance is critical to the success of total knee arthroplasty,” said James Huddleston, MD, of Stanford University. “Exactech’s ligament-driven technology provides full-range intraoperative balance data, allowing surgeons to create patient-centric plans with consideration for the ever-important mid-flexion stability. The results of this study are powerful in demonstrating the beauty of personalized knee arthroplasty and the importance of addressing instability and improved satisfaction.”

The study evaluated the clinical outcomes of a total of 200 patients who underwent computer-assisted cemented, posterior-stabilized TKA with gap balancing at 0 and 90° compared to patients with full-range gap balancing leveraging GPS and the Newton knee balancing technique. The results demonstrated that Exactech’s ligament-driven knee technology did not significantly increase operative time, and the patients, on average, experienced an eight-hour shorter hospital stay and yielded clinically significant improvements on Knee Society Knee and Function scores.

“This new independent study exemplifies the importance of personalized surgical planning based on reliable soft-tissue acquisition throughout the arc of motion and shows that even for the best surgeons the adoption of our advanced technologies may translate into clinically significant improvement in results,” said Laurent Angibaud, Exactech Vice President of Development, Advanced Surgical Technologies. “In contrast, other technologies that do not consider soft tissue as part of their surgical planning have shown that odds of revision in TKA for instability and pain were significantly higher than patients who had conventional TKA.”

Powered by Active Intelligence®, Exactech’s ligament-driven balancing technology provides orthopaedic surgeons with dynamic soft tissue analytics, pre-resection operative insights and full-range personalized planning designed to help simplify, evaluate, and execute reproducible balanced total knee replacement surgery.
