The supplier of the implant, Exactech, Inc. said: “The study was based on a large collection of technical reports on all the total knee arthroplasty cases performed in the entire application history of ExactechGPS, Exactech’s surgeon-controlled computer-assisted surgery for improved reproducibility and efficiency in total joint arthroplasty. The results demonstrated high accuracy and precision in resection alignment with the use of the system by users with varying levels of experience.”
“Two additional posters, featuring the Truliant Knee System’s femoral and patellar designs, were recognized as poster finalists in the same category.
According to Co-Author H. Morton Bertram III, M.D., “Truliant’s new design has had a very positive impact. I find that I can improve coverage of the native bone with the more anatomic patella.”
“The recognition from ORS is an incredible achievement that shows our commitment to research and surgeon input to deliver a clinically engineered system that addresses surgeons’ needs for reproducibility in total knee arthroplasty,” said Vice President of Knee Marketing Joseph Pizzurro. “We are pleased to receive such a positive response to Truliant’s comprehensive platform, including its state-of-the-art ExactechGPS knee applications and anatomical implant design.”
Richard J Friedman, M.D., chief of Shoulder and Elbow Surgery and professor of Orthopaedics at the Medical University of South Carolina in Charleston, told OTW, “The most exciting thing about Exactech’s new knee system is its comprehensive approach to solving reproducibility and efficiency in total knee replacement procedures. The Truliant femoral implants offer excellent fit with an option to increase bone coverage using its new anatomically shaped patellar design. With both mechanical and computer-assisted surgical options, the system adapts to various surgical scenarios and offers accurate and precise guidance with its ExactechGPS knee applications.”

This is a fascinating development. In my practice we've seen similar outcomes with the revised protocol. The key differentiator seems to be patient selection criteria. Has anyone else noticed the correlation with BMI thresholds?
Great point. I'd push back slightly on the conclusion, the sample size in the cited study is too small to draw population-level inferences. That said, the directional signal is compelling and worth a larger RCT.
We implemented a similar approach last year. Early results are promising but we're still gathering 12-month follow-up data. Happy to share our protocol if anyone is interested.
