A joint project was undertaken to develop a system that provided surgeons with better information during orthopedic surgeries. The system tracked the alignment of a patient's hip by using a 3-D infrared camera and calculated the mechanical stress within the joint by using a computational model. The biomedical guidance system (BGS) was to improve decision making during joint surgeries by predicting the underlying mechanical loading of the joint. The system was developed to improve a type of hip realignment known as periacetabular osteotomy (PAO) and the application was to be extended to other areas of computer-assisted orthopedic surgery.
