3D Patellar Shape is Associated with Patellar Dislocation: an Automated Coordinate Algorithm and Statistical Shape Modeling Analysis

Key Points

• Patellar dislocation is significantly associated with specific shapes of the patella, indicating inherent biomechanical risks.
• Key evidence shows that variations in patellar shape correlate with dislocation rates in a defined population of individuals.
• Automated coordinate algorithm and statistical shape modeling were employed to analyze patellar geometries in this study.
• Findings may enable improvements in patellar assessments to prevent dislocations, though further validation is necessary.
