Arthroscopic Versus Open Resection of Infrapatellar Fat Pad Tumour

Abstract

Background : While few comparative studies exist, it has been suggested that open resection of Hoffa’s fat pad tumour provides inferior results when compared with the all - arthroscopic technique. Purpose : The purpose of this study was to compare the intermediate - term results of patients undergoing arthroscopic versus open resection for the treatment of Hoffa’s fat pad tumours. Methods: We report prospective study of 15 patients with symptomatic Hoffa’s fat pad impingement. Patients were divided into two groups (9 arthroscopic, 6 open). The mean follow - up for group I (open) and group II (arthroscopic) was 2.3 years and 1.2 years, respectively . The diagnosis was made by clinical exam, MRI imaging and verified by a natomopathology. Lysholm score and American knee score were obtained pre and post operative and at final follow up. Each patient completed a questionnaire assessing their scar satisfaction, percentage of normal knee function and willingness to have the sur gery again. Risk factors for poor outcomes were analyzed. Results: There was a significant improvement in their symptoms and function after the surgery at
