Effect of patient-specific model scaling on hip joint reaction force in one-legged stance study of 368 hips
Original language description
Estimation of hip joint loading is fundamental for understanding joint function, injury and disease. As the measurement of the forces acting in the hip joint is technically complex and invasive, large majority of studies estimate hip force by a mathematical models. Recent studies have shown that the generic scaling fails to predict accurate muscle-tendon lengths, muscle moment arms, and muscle forces in comparison to modeling of an individual hip based on geometrical parameters obtained from MR scans. It was suggested that scaling by geometrical parameters obtained from standard antero-posterior radiograms could improve the accuracy of determination of the hip joint reaction force. This study analyzes the effect of three different scaling methods on the calculated hip joint reaction force subject to patient-specific geometry. Geometrical parameters were obtained from standard anteroposterior radiograms of 308 hips while the force was calculated by a previously validated three dimension
