Failed meniscus repair.

This report describes problems arising after an arthroscopic meniscal refixation using the biodegradable Clearfix screw system (Innovasive Devices, Marlborough, MA). A serious problem arose in the form of migration of a meniscal screw that had been inserted in accordance with the manufacturer's instructions. Dislocation of the screw led to pain on the medial aspect of the knee joint and irritation of the infrapatellar branch of the saphenous nerve. The case reported here is a first analysis of the potential complications associated with the use of this meniscal refixation system.
