Abstract

Introduction
Para-articular masses are not clear enough in terms of their etiology and nomenclature. Although surgical removal of the mass is the preferred treatment, long term follow-up after surgical treatment has not been reported yet. The current study presents a patient with the osteo-cartilaginous mass of infrapatellar region, diagnosed after a trauma. This case has the longest follow-up period in the literature.


Case Presentation
A 52-year-old female patient referred after falling down on her right knee. Lateral radiographs of the knee revealed a mass in the infrapatellar area. The case was treated surgically by total excision of the mass. The mass was extra-capsular with lobular and irregular shape. After mass removal the clinical course was uneventful and at the 10-year follow-up, no signs of recurrence were evident clinically or radiologically.


Conclusions
Tumor-like lesions within the infrapatellar fat pad should remind the para-articular osteochondroma. Although its etiology has not yet been elicited, operative removal of the mass is the preferred treatment of choice and also curative in long-term follow-up.
