RESUMEN
OBJECTIVE:To evaluate clinical efficacy through comparing the change of CT image in infrapatellar fat pad before and after Xiaoding ointment in the treatment of acute patellar bursitis of knee joint. METHODS:73 patients with acute patellar bur-sitis were randomly divided into observation group(39 cases)and control group(34 cases). Observation group was given Xiaoding ointment for local application,qd,7 d as a courses,3 courses in total;control group was given triamcinolone acetonide 30 mg af-ter the extraction of articular cavity effusion,once a week,totally for 3 times. All patients of two groups underwent knee CT exami-nation for observation of the infrapatellar fat pad and articular cavity effusion volume change before and after treatment. Clinical ef-ficacies were compared between 2 groups. RESULTS:CT image alterations of treatment group showed that infrapatellar fat pad den-sity were decreased,anteroposterior diameter,vertical diameter,internal to external diameter were significantly reduced. The total effective rate of treatment group was 92.31%,which was better than that of control group(88.24%),with statistical significance (P<0.05). CONCLUSIONS:Xiaoding ointment demonstrate markedly curative effects in the treatment of acute patellar bursitis, and CT image is an effective method for diagnosis of infrapatellar fat pad.
