Zimmer Biomet introduces X-ray-based patient-specific instrument for TKR
Zimmer Biomet Holdings Inc. introduced the X-PSI Knee System, a surgical planning system that allows for patient-specific implant positioning solely utilizing X-ray technology.
Used with Zimmer Biomet’s flagship total knee brands, the X-PSI Knee System allows surgeons to use X-ray images to generate 3-D anatomic models, according to a company press release. Surgeons then utilize Zimmer Biomet’s Patient Specific Instruments Planner to view the patient’s anatomy and develop a 3-D customized surgical plan, which is used to manufacture patient-specific guides and bone models intended to improve implant fit and placement accuracy, the release noted. The X-PSI Knee System will be initially launched in five countries across the European Union.
“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,” Dan Williamson, joint reconstruction group president of Zimmer Biomet, said in the release. “Conversely, virtually every candidate for joint replacement surgery undergoing 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.”
