Knee injuries are especially common in jumping athletes, and, in particular, elite basketball players. We present an update two years into a multi-site study analyzing the results of a common phantom in assessing biases across and within MRI scanners, as well as to characterize the effectiveness of recruitment, assessment, and study design strategies. It was shown that more timepoints of quantitative values potentially corrects for quantitative biases longitudinally within one scanner. As attrition rates are high for athletes in general, consistent and effective methods of recruitment, early identification of key athletes, and standardized methods of assessment are all necessary.
