Onkos Surgical has completed the 1,000th case using its personalized, 510(k) cleared My3D patient-specific pelvic implant platform. The count covers pelvic reconstructions in which a 3D printed implant was designed specifically for the individual patient rather than selected from a catalogue of sizes.
The company presents the figure as evidence of adoption rather than a one-off technical achievement. The cases it describes share a common obstacle: anatomy that standard implants cannot address, whether because of bone loss, tumour involvement, or a revision history in which earlier reconstructions have already altered the pelvis. In those situations, Onkos argues, an individualized approach is not a premium option but the only workable one.
“Reaching the 1,000th personalized My3D pelvic implant case is a meaningful milestone for Onkos and for the surgeons who partner with us on solutions for their patients” said Onkos Founder and CEO, Patrick Treacy. “Our personalized approach is built around understanding each patient’s unique anatomy and helping surgeons translate that understanding into a thoughtful reconstruction plan.”
What the 1,000 cases have in common
My3D is a bundled service rather than a single product. Onkos combines collaborative case planning, advanced imaging, 3D anatomic modelling and patient-specific implant design, with the stated aim of supporting surgeons through both the planning and the execution of the procedure. Each of those elements feeds the next: imaging becomes a 3D anatomic model, the model becomes the basis of a planning discussion with the surgeon, and the planning output defines the geometry of the printed implant.
That sequence is what separates personalized pelvic reconstruction from conventional implant selection. A surgeon working with off-the-shelf components chooses the closest available fit and adapts the bone to it. A surgeon working from a patient-specific design does the reverse, with the implant shaped around the defect that the resection will leave behind. Onkos frames the pelvis as the region where that inversion matters most, given the complexity of the anatomy and the difficulty of restoring it once significant bone has been removed.
The company also makes a claim that goes beyond clinical capability. Alongside the case milestone it points to what it calls world-class delivery times and a commercially competitive personalized pelvis reconstruction platform, a statement aimed squarely at the two objections that have historically limited patient-specific implants, namely lead time and cost.
Onkos added it remains committed to funding advanced tools that unify surgical preparation, 3D anatomical models, custom implants, and streamlined procedures for intricate orthopedic conditions.
Personalization as a product line, not a favour
Printing a patient-specific pelvis has been possible for a decade; doing it fast enough and cheaply enough to be a routine option has not. By bundling planning, imaging, modelling and design into My3D and claiming competitive delivery times and pricing, Onkos is arguing personalization can carry catalogue-product discipline. The 1,000 cases are the proof point.
restor3d is attacking the same bottleneck in other joints, and its scale shows what productization looks like: more than 520 surgeons across 740 hospitals in 2024, with cleared implants for shoulder, hip, knee, foot and ankle. Its Ossera AFX launch runs the logic backwards, standardized Cylinder, Dome and Pill geometries derived from long-term analysis of patient case data. Personalization data mined to build off-the-shelf parts.
Materialise works the same seam upstream. Materialise added custom PEEK implants alongside titanium in its cranio-maxillofacial portfolio, both handled through one digital planning and case management system, with cases tracked in Mimics Flow.
A thousand cases is proof the pipeline holds at volume, turning a procedure that used to be improvised into one surgeons can order.
