Case Study: The Chinese University of Hong Kong achieves faster, more accurate and lower-cost orthopaedic surgeries with Stratasys 3D printing

3D Models Improve Hospital's Orthopaedic Surgeries

The Chinese University of Hong Kong (CUHK), led by Professor Kwok-sui Leung at the Prince of Wales Hospital, needed a way to improve the accuracy, safety and planning of complex orthopaedic surgeries while cutting time and costs. Surgeons traditionally relied on CT scans and experience, validating plans in the operating room, which made precision procedures like bone cancer resections, pelvic fracture repairs and corrective osteotomies challenging and time-consuming.

Stratasys supplied a Fortus® 3D Production System using FDM Technology to print patient-specific bone models, sterilizable surgical guides (made in PC-ISO®) and single‑use tools for pre-surgical rehearsal and intraoperative use. The Stratasys solution shortened surgeries by about one hour on average, improved implant fit and success rates, reduced bleeding and infection risk, enhanced patient communication, and produced guides for roughly HKD100 each—delivering measurable time, cost and clinical benefits.
