The patented device enhances the precision of rotational alignment for femoral cutting guides during total knee arthroplasty. By integrating a stylus with an anteroposterior (AP) sizer and incorporating interchangeable anterior and posterior pin guides, the instrument adapts to diverse anatomical conditions. This technology improves surgical accuracy and optimizes patient-specific outcomes.

Building on an earlier South Korean patent, this U.S. patent strengthens Yonsei Sarang Hospital’s position in the global medical device market. “Precise osteotomy is critical to successful joint replacement surgery,” Dr. Koh stated. “This patent underscores our globally recognized technological expertise.”
Yonsei Sarang Hospital continues to advance research into novel surgical instruments and treatment methodologies, with plans to share findings at international conferences and pursue commercialization opportunities.
