Discoid Meniscus

  • Introduction

  • Conservative Treatment

  • Surgical Treatment

The meniscus is a pad like piece of cartilage which sits between the thigh and shin bone (the femur and tibia). It acts as a cushion protecting the bones during movement and acts as a shock absorber. The knee joint has two menisci – the medial meniscus on the inside of the knee and the lateral meniscus on the outside of the knee.

In a healthy knee the menisci are shaped like a crescent. However, some patients may have a variant discoid meniscus which is thicker than normal and will typically be oval or disc-shaped. A discoid meniscus can be more prone to injury due to its abnormal shape and have an increased likelihood of becoming struck in the knee. In general, meniscus tears do not heal because there is a lack of a strong blood supply to the area causing an absence of nutrients needed for healing.

Symptoms of discoid meniscus may include, pain, stiffness, swelling, a popping or locking of the knee and the inability to fully extend the knee.

A non-surgical approach to treating a discoid meniscus involves working with your doctor to increase your range of motion. Pain management efforts and strength training may also be recommended depending on the severity of the injury.

Typically, the surgical approach to treating this condition is to perform a knee arthroscopy. It is usually an outpatient procedure in which patients are able to return home within a few hours. The approach to surgical treatment is highly dependent on the type of discoid meniscus and can range from needing to cut and re-shape the meniscus in a crescent shape, repairing or stabilizing tears with stitches, or trimming away torn portions.
