Abstract

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. Conclusion: Foreign body reaction from a misplaced all-inside meniscal device is a previously unreported complication. Diagnosis is challenging as MRI and arthroscopy can be unrevealing. Diagnostic ultrasound was able to identify the foreign body reaction, confirm the diagnosis by facilitating diagnostic local anesthetic injection, and guide surgical excision. Sonographic evaluation should be considered in patients presenting with ongoing knee pain after all-inside meniscus repair.
