About

Constantinos Nikou is a leading innovator in computer-assisted orthopedic surgery, with foundational contributions spanning image-guided navigation and semi-active robotic systems for joint replacement. His seminal 1998 work on an image-guided navigation system to measure intraoperative acetabular implant alignment (414 citations) was among the first to address the critical, previously unmeasurable effects of patient positioning and pelvic motion during total hip arthroplasty—fundamentally advancing the precision of implant placement. Nikou further pioneered precision freehand sculpting (PFS), a handheld semi-active robotic technology for bone shaping that operates within a surgical navigation framework, offering dual control modes for enhanced accuracy in unicondylar knee replacement. His more recent work on an image-free handheld robot for bi-cruciate retaining total knee replacement demonstrates continued leadership in developing anatomically designed, patient-specific solutions aimed at improving knee stability and proprioception for active patients. Through these innovations, Nikou has helped bridge the gap between traditional surgical technique and real-time intraoperative measurement, directly impacting the safety and outcomes of joint replacement surgery.
