Measurement of Artificial Knee Joint Kinematics using Pattern Matching Method

Introduction An increase in demand of Total Knee Replacement (TKR) has necessarily required us to design a better TKR from durability and endurance aspects. Measurement of prosthetic kinematics will bring us significant information on the TKR design. The image-based technique may be highly feasible for in-vivo measurement as compared to other sophisticated techniques. In this study, the pattern matching theory was developed and computer model studies and in-vitro measurements were performed to assess the feasibility of using an X-ray fluoroscopy based technique for the measurement of 3-D kinematics of TKR.
