What is a meniscus?

Introduction

The meniscus is a ‘C’ shaped structure that acts as a cushion to protect the smooth joint surfaces of the knee joint. Often known as the footballers cartilage it can be easily injured.

There are two of these structures – one on each side of the knee joint - and if removed at an operation following injury then there is less protection of the bearing surfaces such that the joint will wear out sooner.  

Usually only a small part is removed and the risk of later problems is low. Symptoms will include pain and swelling of the knee after activity and limitation in tolerance of impact type sports. Symptoms may gradually get worse over the years as the joint slowly wears
