Better visualization of patello femoral joint space by using different x-ray tube angulation

Aim of the study was to evaluate better visualization of patellofemoral joint space among various x-ray tube angulation of 15°,20°,25°cranially with flexion of 45° with use of the anterior border of the patella and tibial tuberosity. Objectives: 1. To determine the skyline or axial view has provided useful information about the morphology and anatomy of the patellofemoral joint. 2. To assess the clinical handiness of the new horizon, see imaging procedure as a standard strategy into clinical practice. Methodology: our database consisted of various x-ray tube angulations of 15°,20°,25°cranially with flexion of 45° of the patella of the same patients. We are taking images from three different angles. And the IR read to the reader and image displayed and the evaluation will be made by blinding the radiologist and the score for the different projection will be recorded. The Final score will be tabulated according to the evaluation given by the radiologist. obtained with use of inferior –superior view of skyline projection for the radiographic diagnosis of knee-joint diseases. Result: A total of 29 patients ranging in age from 20 to 70 years with mean age 39.21 years. Conclusion: This prospective clinical study confirmed that the best visualization of the patellofemoral joint space with the skyline-view imaging technique, which uses the 25° x-ray tube angulation with the 45° knee flexion in the supine position. That provides more accurate axial images of the patella.
