摘要

In the Asia, obesity is defined as when the Body Mass Index (BMI) is equal or greater then 25 kg/m2. It is technically more difficult to obtain a good diagnostic radiographic examination of the patellofemoral joint for the obese patient suffering from the degenerative knee joint disorder as because of postural change caused by body status. By using modified Merchant method, that is patient’s vastus lateralies muscle paralleling the radiographic table, this will overcome the postural change created by the obese patients. We collected twenty obese patients who BMI greater than 30kg/m2. We examined the patellofemoral joint of these patients using the modified Merchant method. The result of this study revealed the diagnostic radiographic quality was excellent in all the patients(100%) when modified Merchant method was used, whereas the radiographic quality was poor but with still acceptable diagnostic value in 85% of the patients and very poor radiographic quality with no diagnostic value in 15% of the patients when using usual Merchant method. For nonobese patients but bulky thigh, We also suggest using modified Merchant method for radiographic examination of the patellofemoral joint.
