New Complication Associated With All-Inside Meniscal Repair Device Ultrasound-Aided Diagnosis and Operative Localization of Foreign Body Reaction

Background:The importance of meniscal preservation has become widely accepted, and meniscal repair techniques have evolved over recent years. With new techniques come new complications, which are critical to recognize.Purpose:To describe a new complication of foreign body reaction from a nonabsorbable suture anchor associated with improper placement of the all-inside meniscal device.Study Design:Case series; Level of evidence, 4.Methods:This study was a retrospective review of 3 patients who developed pain associated with a foreign body reaction from a misplaced all-inside meniscal device.Results:All patients had a delayed diagnosis (6 months to 8 years) and negative magnetic resonance imaging (MRI). Diagnostic ultrasound identified the misplaced suture with foreign body reaction and was used to guide a diagnostic injection of local anesthetic prior to surgical intervention. Intraoperative ultrasound guidance was utilized to precisely localize and excise the suture material and associated reactive tissue....
