ReviewClassifying Cam Morphology by the Alpha Angle: A Systematic Review on Threshold Values.
The alpha angle is the most often used measure to classify cam morphology. There is currently no agreement on which alpha angle threshold value to use. ⋯ Based on the available evidence, mostly based on studies using ROC curve analysis, an alpha angle threshold of ≥60° is currently the most appropriate to classify cam morphology. Further research is required to fully validate this threshold.
