Musculoskeletal Motion Analysis

Investigating patellar motion using weight-bearing dynamic CT: normative values and morphological considerations for healthy volunteers. DOI: 10.1186/s41747-024-00505-6

We explored 4D CT scanning to track mandibular motion using a novel phantom model on a six degrees-of-freedom platform. This method captured complex jaw movements with minimal displacement and rotation variation, at radiation levels similar to standard head CT. This approach could be valuable for evaluating the motion of jaw prostheses, potentially guiding improvements in design.

Our dynamic CT study on patellar motion in weight-bearing conditions established normative values in healthy subjects. We found that lateral displacement of the patella is significantly influenced by the lateralisation of the patellar tendon, particularly in males and those with patella alta, while trochlear groove morphology had minimal effect. These findings provide clinicians with valuable benchmarks for assessing knee stability and patellar tracking.
