Zimmer Biomet (NYSE:ZBH) said on Thursday it launched its X-PSI knee system, an X-ray-based, patient-specific surgical planning system designed for patient specific implant positioning using X-ray tech.
The X-PSI system is designed for use with all of the Warsaw, Ind.-based company’s total knee brands, and allows surgeons to use X-ray images to generate 3D anatomical models. The system is then used to view the patients’ anatomy and develop a customized 3D surgical plan, the company said.
“The use of innovative preoperative planning to enable patient-specific customization has the potential to become the gold standard in joint replacement care; however, its widespread clinical utility has been limited by its reliance on MRI and CT imaging, which are less accessible and not typically used for preoperative evaluation. Conversely, virtually every candidate for joint replacement surgery undergoes X-ray imaging, so we are thrilled to debut the first CE Marked, X-ray-based patient specific instrument system, and extend the benefits of customized surgical planning to joint replacement patients across the European Union. This new offering was conceptualized and developed in collaboration with Dr. Mohamed Mahfouz, Professor of Biomedical Engineering at the University of Tennessee, who pioneered the original concept,” joint reconstruction group prez Dan Williamson said in a prepared statement.
Zimmer Biomet touted the X-PSI system as the world’s 1st X-ray based patient specific system for total knee replacement surgery with CE Mark approval in the European Union. The company said it is its 4th patient specific guide in its personalized solutions franchise, and is slated to be launched in 5 countries in the EU.
“The growing use of MRI and CT-based planning software to customize implant placement has meaningfully improved patient outcomes in joint replacement surgery. Our study found that X-PSI Knee System, which uses X-ray imaging with Zimmer Biomet’s patient specific instruments planner, yields comparably high implant placement accuracy as MRI and CT-based systems, while significantly improving accessibility and clinical utility to a broader patient population,” X-PSI IDE trial lead investigator Dr. Raju Ghate of Evanston, Ill.’s NorthShore University HealthSystem said in a press release.
In May, Zimmer Biomet said it inked a deal with device incubator Bonutti Research for 2 families of patents related to knee technologies. The company licensed a patent which Bonutti says “adds to the strength” of the Persona personalized knee system and its NexGen Complete knee solution.
