Correlation Between Merchant’s Standard Q Angle and TT-TG Distance
We observed a strong positive correlation between the SQA and the TT-TG distance in anesthetized patients with normal patellar height and a normal LTI. However, in awake patients and those with anatomic risk factors for recurrent patellar instability, correlations between the SQA and the TT-TG distance were weakly positive or nonsignificant. The SQA may provide useful information, but not in patients with anatomic findings that put them at increased risk for patellofemoral instability.
