چکیده
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: A total 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.

متن کاملReliability of Persian Early Computed Tomography Score in Patients with Brain Infarction
Background: The one-third middle cerebral artery (1/3 MCA) method and Alberta Stroke Program Early Computed Tomography Score (ASPECTS) were used to detect significant early ischemic changes on brain computed tomography (CT) of patients with acute stroke. We designed the Persian Early CT Score (PECTS) and compared it with the above systems. Methods: The tomograms were chosen from the stroke data...
متن کاملThe Relationship between Range of the ankle motion, Q angle and back stroke kicking on male Swimmers
The purpose of this research is to survey the relationship between range of the ankle motion and Q angle and back stroke kicking on male swimmers. 34 on available boy students swimmers were selected with mean and SD of age 23.68±2.28 years, weight 71.88±9.35 kg and height 176.11±5.52 cm in this study. First, Right and Left Leg Q angles (to supine position), Range of Dorsal flexion and plan...
متن کاملPatellar instability in Indian population: relevance of tibial tuberosity and trochlear groove distance
INTRODUCTION The tibial tuberosity to trochlear groove (TTTG) distance in the western population is extensively studied through various modalities such as X-rays, computerised tomography and magnetic resonance imaging. However, to our knowledge there is very little or no literature support to indicate that TTTG distance has been studied in the Indian population. METHODS We therefore undertook...
متن کاملSystematic technique-dependent differences in CT versus MRI measurement of the tibial tubercle-trochlear groove distance.
BACKGROUND The tibial tubercle-trochlear groove (TTTG) distance is used to quantify the degree of lateralization of the patellar tendon insertion on the tibial tubercle relative to the deepest part of the trochlear groove. Disagreement exists as to whether the TTTG distance measured on computed tomography (CT) and magnetic resonance imaging (MRI) can be considered equivalent. PURPOSE To compa...
