Abstract

We report a case of posterior hoffitis in a middle-aged woman with no prior history of significant major trauma. Her symptoms of anterior knee pain and limited extension failed conservative measures. Preoperative magnetic resonance imaging demonstrated a significantly thickened infrapatellar plica tethering Hoffa`s fat pad in the anterior interval of the knee. Arthroscopic resection of the infrapatellar plica resulted in complete resolution of symptoms within six months following the surgery.
