Abstract

We have been developing a motion analysis system for patients after total hip arthroplasty (THA). This system aims to visualize skeletal movement and estimate any complications after THA. In this research, we added a new function to our system, which enables analysis of skeletal movement in real-time. For this purpose, we utilized a skeletal model constructed from computed tomography (CT) and optical motion capture data captured in real-time. By combining these two data sets, we were able to display skeletal movement in real-time. Usually, it is difficult for THA patients to assess the condition of their hip joint during movement because of the complexity of the hip structure. Using the proposed system, patients can easily recognize the condition of their hip joint during movement, and clinicians can estimate the parameters risking dislocation in real-time. In the near future, we intend to reduce the time required for construction of skeletal models, and then routinely apply this system in clinical situations.
