Automatic Measurement of Distal Femoral Parameters Based on Statistical Models

Abstract— Osteoarthritis and rheumatoid arthritis are common orthopedic complications, and Total Knee Arthroplasty (TKA) replacement is now the standard treatment for osteoarthritis and rheumatoid arthritis of the distal femur. The measurement of distal femoral parameters can help orthopaedic surgeons to select suitable replacement prostheses, and can also help prosthesis manufacturing companies to produce prostheses that are more compatible with the national population. The method uses an alignment algorithm to derive a representative statistical model of the femur, and on the basis of this model, the automatic measurement of the distal parameters of individual femurs is performed. The experimental results on the data set provided by the PLA General Hospital showed that the difference between the results measured using this method and the results measured manually by the physician was about 3 mm, and the method was able to automatically measure the distal femur parameters quickly and efficiently.

Index Terms— distal femur, statistical model, alignment algorithm, automatic measurement of distal femur parameters.
