Accuracy of model-based tracking of knee kinematics and cartilage contact measured by dynamic volumetric MRI

Accuracy of model-based tracking of knee kinematics and cartilage contact measured by dynamic volumetric MRI

Highlights • Accuracy of knee kinematics measured from a novel dynamic MRI sequence is presented. • Three-dimensional kinematics are tracked with precisions less than 0.8° and 0.5 mm. • Cartilage contact locations can be estimated with a precision less than 0.5 mm. • The sequence has use in finding...

Zusammenfassung:Highlights • Accuracy of knee kinematics measured from a novel dynamic MRI sequence is presented. • Three-dimensional kinematics are tracked with precisions less than 0.8° and 0.5 mm. • Cartilage contact locations can be estimated with a precision less than 0.5 mm. • The sequence has use in finding links between joint mechanics and osteoarthritis.
