Under-meniscal portal: an alternative portal for an easy access to the medial and lateral menisci

摘要

Approach to the pathologies in the posterior horn of the medial meniscus in a tight knee may be a challenging technique to the arthroscopic surgeon in certain patients. The pie-crusting technique of the medial collateral ligament which can be done percutaneously to open up a tight posteromedial compartment would be a good option in such patients. Here, the authors introduce a useful alternative portal for approaching the posterior horn of the medial meniscus, the under-meniscal portal. The under-meniscal portal is located under the menisci and can be placed safely and easily without any complication. It is also helpful for approaching the unstable underside of the horizontal tear in the anterior horn of the lateral meniscus. The authors suggest the under-meniscal portal as a good alternative portal for managing challenging lesions in the posterior horn of the medial meniscus and the anterior horn of the lateral meniscus.
