Abstract:   (9012 Views)


  Background: The purpose of this study was to evaluate the significance of the Q

  angle with respect to the patella position. We assess the correlation between the Q angles (calculated by clinical exam) in different positions and CT indices (with more

  impression on TTTG).

  Method: Atotal number of 68 knee joints of 50 cases entered the study. Clinical

  examination was used to measure Q angle (in 3 positions of sitting, standing and

  supine). CT scan performed in 2 axial view of proximal tibia, and distal femor for

  measurement of Tibial tuberosity-trochlear groove distance (TTTG) and other CT

  indices. Correlation between main variables calculated.and analysed with spss.

  Results: Supine Q angle were strongly correlated with standing Q angles and

  moderately with sitting Q angle. Sitting Q angle was moderately correlated with

  supine and standing Q angle and weakly with PTA. we found no other significant correlation between Q angle and CT indexes.

  Discussion: Our findings suggest that Q angle is not a valuable index for predicting

  the presence of patelofemoral malalignment.
